Questions, Answered

Everything you need to know about our tools, privacy, and accounts — plus what the optional Premium plan adds.

Every tool is free to use

No sign up, no trial, no strings attached — and that is the permanent model, not a promotion. The optional Premium plan ($25/year) adds extra features that vary by tool, like cloud backup and cross-device sync, plus premium member guides and guaranteed unlimited use.

General Questions

What is The Dollar Web? +

The Dollar Web is an ecosystem of functional web apps that help users accomplish productivity tasks without paying hefty monthly fees. It's built for entrepreneurs, students, small business owners, office workers, teachers, event planners, and everyone in between who just needs to get something done. Every tool on the site is free to use.

What does "client-side processing" mean? +

Client-side processing means all file processing happens directly in your web browser on your own device. When you upload a file to one of our tools, it never gets sent to our servers or stored anywhere online. Instead, your browser does all the work locally on your computer, tablet, or phone. This ensures your files remain private and secure, while also providing faster processing since there's no need to upload or download files to/from a server.

How much do the tools cost? +

Nothing. Every tool on The Dollar Web is free to use, and that is the permanent model, not a promotion: no sign-up, no trial, no credit card. The optional Premium plan ($25/year) adds extra features that vary by tool, such as cross-device cloud backup, plus premium member guides, priority support, and guaranteed unlimited use. As the site grows, free use of some tools may include fair-use limits; Premium never will.

How do I access my account settings? +

Once you're logged in, simply click the "Account" button in the navigation bar, then select "Account Settings" from the dropdown menu. This will take you to your account dashboard where you can manage all your account preferences.

Can I change my password? +

Yes, you can change your password anytime in your account settings. Note that users who authenticate with Google do not have a password with The Dollar Web, as authentication is handled through Google's secure system.

How do subscriptions work? +

A Premium subscription costs $25/year and adds extra features on top of the free tools: cloud backup and sync on supported tools, premium member guides, priority support, and guaranteed unlimited use. Every tool remains free to use without one. You can add or cancel a subscription at any time through your account settings, with no cancellation fees or complicated processes.

What happens if I delete my account? +

You can delete your account and all corresponding data through your account settings. Important note: if you delete your account while a Premium subscription is active, that subscription will be lost even if you recreate your account later. If this happens accidentally, you can email support@thedollarweb.com and we'll help restore your access.

Do you guarantee tool performance? +

We don't provide guarantees on tool performance. The Dollar Web is a bootstrapped company, which is how we're able to offer every tool free of charge and keep costs low overall. While we work hard to ensure our tools function properly, our lean approach to service delivery is part of what makes this possible.

Tool-Specific Questions

Open Graph Generator

https://thedollarweb.com/tools/open-graph-generator.html Free
+
What is an Open Graph image?
It's the image that appears in the preview card when your link is shared on social media or messaging apps. The standard size is 1200×630 pixels, and it's referenced by an og:image meta tag in your page's HTML. This tool designs that image and gives you the matching tags.
Can I see how it will look before publishing?
Yes. As you type, the tool shows realistic X / Twitter, Facebook, and LinkedIn preview cards using your image, headline, description, and domain — so there are no surprises after you post.
What do I get to download?
A 1200×630 share image as PNG or JPG, plus the ready-to-paste og: and twitter: meta tags. Upload the image to your site or CDN, set its address as the og:image, and paste the tags into your page's <head>.
Can I use my own background or logo?
Yes. Choose a gradient, a solid color, or upload your own background image (a dark overlay is added automatically for readability), and optionally add a logo. You can also set the text color, accent color, and font.
Is my image uploaded anywhere?
No. Everything is composited in your browser — your text and any uploaded image are never sent to a server. It's completely free with no sign-up.

Certificate Maker

https://thedollarweb.com/tools/certificate-maker.html Free
+
What does the Certificate Maker do?
It lets you design a certificate of achievement, completion, or appreciation from one of four templates, add a title, recipient name, body text, date, and up to two signature blocks, then download a print-ready PDF or a high-resolution PNG.
Can I make certificates for a whole group at once?
Yes. Switch to Batch mode and paste one recipient per line — you'll get every certificate at once, either as a single multi-page PDF or a ZIP of individual PNGs. You can also add a comma and a detail after each name and merge it into the text with the {name} and {detail} tokens.
Will it print nicely?
Yes. Certificates are rendered at high resolution on a landscape A4 layout and exported as a true A4 PDF, so they print edge-to-edge on standard paper and stay sharp at full size.
Can I match my brand?
Pick from Classic, Modern, Elegant, and Corporate templates, set your own accent color and font, and add your organization name. The recipient's name scales automatically so even long names stay centered.
Is my roster uploaded anywhere?
No. Everything is generated in your browser — the names you enter are never sent to a server. It's completely free with no sign-up.

Face Dance Animator

https://thedollarweb.com/tools/face-dance.html Free
+
What does the Face Dance Animator do?
It puts your face on a dancing cartoon body — human, dog, or cat. Upload a headshot (yours, a friend's, or your pet's), fit the face into the circle, pick one of four dances (Disco Fever, The Robot, Hula Sway, Party Bounce) and one of eight scenes including Christmas, Halloween, Valentine's, and fireworks, top it with a hat (Santa, antlers, witch, bunny ears, party cone), optionally add a message banner like "Happy Birthday!", and share it as a looping GIF, a WebM video, or a PNG frame.
Is my photo uploaded anywhere?
No. Your headshot never leaves your device — the face is cropped, composited, and animated entirely in your browser, and even the GIF is encoded locally. Close the tab and the photo is gone.
What kind of photo works best?
A front-facing headshot with the face reasonably large in the frame. After uploading, use the zoom and left/right/up/down sliders (or drag inside the preview circle) to center the face — whatever is inside the circle becomes the dancer's head.
Does the GIF loop smoothly?
Yes. One loop is exactly two beats of the dance, and every scene animation is synced to that loop, so the exported GIF repeats seamlessly forever. The tempo slider changes both the preview and the exported file.
Where can I share the result?
On phones, tap Copy / Send GIF and the share sheet drops it straight into iMessage, WhatsApp, Slack, or wherever — no download step. Where supported it copies right to the clipboard. The GIF also pastes into almost anything from a download; use the WebM export for platforms that prefer video, or the PNG frame for a still image.
Is there a watermark or a fee?
Completely free with no sign-up. GIFs carry a small "made with thedollarweb.com" credit in the bottom corner — no paywall stamp across the middle, and the face and the joke stay front and center.

Fancy Text Generator

https://thedollarweb.com/tools/fancy-text-generator.html Free
+
What does the Fancy Text Generator do?
Type any text and it instantly produces dozens of styled versions — bold, italic, cursive script, fraktur, bubble, fullwidth, strikethrough, upside down and more — that you can tap to copy and paste into a social bio, username, or caption.
How does fancy text work in apps that have no font picker?
These styles aren't fonts — they're real Unicode characters that happen to look bold, italic, or decorative. Because they're actual letters, they keep their look anywhere you paste plain text, including Instagram, TikTok, Twitter/X, and Discord.
Will every style show up everywhere?
Almost always, but not guaranteed. A few apps, fonts, or screen readers may not display or read certain styles — if one looks like empty boxes in a particular place, just pick a different style.
Is my text private?
Yes. Everything is generated in your browser — nothing you type is uploaded or stored anywhere.
Is the Fancy Text Generator free?
Yes, it's completely free with no sign-up required.

Favicon Generator

https://thedollarweb.com/tools/favicon-generator.html Free
+
What does the Favicon Generator create?
A complete favicon package in a single ZIP: a real multi-resolution favicon.ico (16, 32 and 48px), PNG icons (16/32/48), an apple-touch-icon (180px) for iOS, android-chrome icons (192/512) for Android and PWAs, a site.webmanifest, and a favicon-tags.html file with the exact <link> tags to paste into your page's <head>.
Can I make a favicon without a logo?
Yes. Besides uploading an image (PNG, JPG, SVG or WebP), you can type an emoji or use one to three letters as a monogram with your own font, text color, and background — handy when you don't have a logo yet.
Can I control how it looks?
Choose a square, rounded, or circular shape, set a background color or keep it transparent, and adjust padding so your mark isn't cramped. Live previews show your icon in a browser-tab mock, as a rounded home-screen app icon, and at 16–64px so you can check it stays legible when it's tiny.
How do I add the favicon to my site?
Unzip the package into your site's root folder, then copy the tags from favicon-tags.html (or use the "Copy HTML tags" button) into the <head> of your pages. That's it.
Is my image uploaded anywhere?
No. Everything is rendered and packaged in your browser — your image is never sent to a server. It's completely free with no sign-up.

UTM Link Builder

https://thedollarweb.com/tools/utm-builder.html Free
+
What is a UTM link?
A UTM link is a normal URL with extra tracking tags added to the end — utm_source, utm_medium, utm_campaign, and optionally utm_term, utm_content and utm_id. When someone clicks it, Google Analytics records exactly which campaign, channel, and content sent that visit, so you can see what's actually working.
Which fields are required?
The website URL is required, and for Google Analytics you should fill in utm_source, utm_medium, and utm_campaign — the builder highlights these and reminds you if they're missing. utm_term, utm_content, and utm_id are optional.
Does it handle encoding and existing parameters?
Yes. Spaces and special characters are URL-encoded automatically so links don't break, and if your URL already has query parameters they're preserved — only the UTM tags are added or updated. There's also an option to force values to lowercase, since UTM values are case-sensitive and inconsistent casing splits your reports.
Can I make a QR code or reuse past links?
Yes. Generate a QR code of any tracking link to print on flyers or packaging, and every link you copy or save is kept in a local history so you can reuse it and stay consistent across a campaign.
Is my data uploaded anywhere?
No. The links and your saved history are built and stored entirely in your browser — nothing is sent to a server. It's completely free with no sign-up.

Video Compressor

https://thedollarweb.com/tools/video-compressor.html Free
+
Is my video uploaded to a server?
No. The Video Compressor runs FFmpeg compiled to WebAssembly directly in your browser, so your footage is read from disk, compressed on your own device, and saved back — it is never uploaded. The only thing downloaded is the one-time, open-source compression engine (about 32 MB, then cached by your browser).
What formats can I compress, and what do I get back?
You can load MP4, MOV, MKV, WebM, AVI, M4V and more. The output is a widely compatible MP4 (H.264 video + AAC audio) with fast-start enabled, ready for the web, email, or messaging apps.
How do I make the file as small as possible?
Choose the "Max compression" quality, and downscale the resolution — dropping a 4K clip to 1080p or 720p shrinks the file dramatically while still looking good on most screens. Removing the audio track saves a little more.
Why does it take a while, and is there a file-size limit?
Because everything runs on your device, speed depends on your computer and the clip's length and resolution — short clips are quick, long 4K videos can take several minutes. We don't impose a size cap, but very large multi-gigabyte files can exceed the memory a browser tab is allowed to use; if a huge file fails, try a lower resolution or trim it first.
Is the Video Compressor free?
Yes, it's completely free with no sign-up and no watermark.

Barcode Generator

https://thedollarweb.com/tools/barcode-generator.html Free
+
What barcode types are supported?
CODE128, CODE39, EAN-13, EAN-8, UPC-A, ITF-14, ITF (Interleaved 2 of 5), MSI, Codabar, and Pharmacode. CODE128 is the best general-purpose choice; EAN-13, EAN-8 and UPC-A are the standard retail product barcodes.
Can I download the barcode as an image?
Yes. Download a PNG at 1×, 2×, or 4× resolution for high-DPI printing, or an SVG that stays sharp at any size. You can also copy the barcode straight to your clipboard as a PNG.
Do I need to calculate the check digit?
No. For EAN-13, EAN-8, UPC-A and ITF-14, enter the base digits and the final check digit is calculated and added automatically. If your value is invalid for the selected format, the preview tells you what the format expects instead of producing a broken barcode.
Can I generate many barcodes at once?
Yes. Paste a list of values (one per line) into the batch generator and download every barcode at once, packaged as a ZIP file, all using your current type and style.
Is my barcode data uploaded anywhere?
No. Barcodes are generated entirely in your browser — your SKUs, part numbers, and codes are never sent to a server. It's completely free with no sign-up required.

Email Signature Generator

https://thedollarweb.com/tools/email-signature-generator.html Free
+
What does the Email Signature Generator do?
It builds a professional HTML email signature. Pick one of five templates, fill in your name, title, contact details, social links, photo and logo, choose your accent color and font, and copy a ready-to-paste signature into Gmail, Outlook, or Apple Mail. A live preview updates as you type.
How do I add the signature to Gmail or Outlook?
Click "Copy signature", then paste into your email client's signature settings — in Gmail that's Settings → General → Signature, and in Outlook it's Settings → Mail → Compose and reply → Email signature. The tool also includes step-by-step instructions for Gmail, Outlook, and Apple Mail.
Will it look right in every email client?
The signature is generated as table-based HTML with inline styles and web-safe fonts only — the format email clients actually render reliably, rather than modern CSS that gets stripped out. For images, hosting your photo or logo at a public https:// URL is the most reliable, since some clients (notably Outlook) block uploaded/embedded images.
Is my information uploaded anywhere?
No. Everything — your details and any photo or logo you upload — is assembled entirely in your browser and never sent to a server. Uploaded images are embedded directly into the signature locally.
Is the Email Signature Generator free?
Yes, it's completely free to use with no sign-up required.

Markdown Editor

https://thedollarweb.com/tools/markdown-editor.html Free
+
What does the Markdown Editor do?
It renders Markdown live. Write Markdown in the editor, paste it in, or drop a .md file, and the formatted result appears beside it as you type. It supports GitHub-flavored Markdown — headings, bold/italic, lists, task lists, links, images, blockquotes, code blocks, and tables — plus Mermaid diagrams.
Can it render flowcharts and diagrams?
Yes. Add a fenced code block with the mermaid language (open with three backticks followed by mermaid) and it renders as a live diagram in the preview. Mermaid supports flowcharts, sequence diagrams, Gantt charts, class and state diagrams, pie charts and more — the same syntax GitHub and GitLab use. When you download your file as HTML, the rendered diagram is embedded so it travels with the document.
Is my document uploaded anywhere?
No. The Markdown is parsed and rendered entirely in your browser and is never uploaded, so unpublished docs and private notes stay on your device. Pasted content is sanitized so it can't run scripts.
Can I download what I write?
Yes. Download your Markdown as a .md file, or export a self-contained, styled HTML page that looks the same anywhere you open it — no internet required. You can also copy the rendered HTML source to paste into a CMS or email.
How do I just read without the editor?
Use the view switch at the top to flip between Split (editor + preview), Editor only, and a clean Preview-only reading mode.
Is the Markdown Editor free?
Yes, it's completely free to use with no sign-up required.

Meme Maker

https://thedollarweb.com/tools/meme-maker.html Free
+
What does the Meme Maker do?
It lets you build a meme in your browser. Pick a stock meme template or upload your own photo, add as many text captions as you want, drag the text into place on the image, and then download the finished meme as a PNG or JPG — or copy it straight to your clipboard.
How do I save the meme to my phone's photo library?
On phones, tap "Save to Photos" — the share sheet opens with the meme attached, and choosing "Save Image" puts it straight into your camera roll (or share it directly into the group chat from the same sheet). Computers get the classic PNG/JPG downloads and clipboard copy.
Where do the stock templates come from?
The templates are original photos owned by The Dollar Web. They're loaded into the tool from our /memes folder, which means you can use them freely without worrying about third-party copyrights.
Can I use my own photo?
Yes. Switch to the "Upload your own" tab to drag-and-drop a JPG, PNG, GIF, or WebP up to 20MB. You can also paste an image directly from your clipboard with Ctrl+V (Cmd+V on Mac).
How do I position text on the meme?
Click any text on the canvas to select it, then drag to move. You can also nudge a selected layer with the arrow keys (Shift + arrow for larger steps) and delete it with Backspace or Delete.
What can I customize per text layer?
Font, size, fill color, outline color and thickness, rotation, alignment, bold/italic, and uppercase vs. mixed-case. Each layer is independent, so the top caption can be classic Impact white-on-black and a sticker-style note can be Comic Sans red.
Can I add a colored border above or below the image?
Yes. Use the Padding slider to add a band of color around the image, then change the border color with the color picker. This is great for the "white-band-with-text" meme style.
Does my photo get uploaded anywhere?
No. The image stays in your browser the entire time — rendering, text layout, and export all happen on your device. Nothing is sent to a server.
Is this tool free to use?
Yes — full-featured meme creation with templates, multi-layer text editing, clipboard copy, and PNG/JPG export is completely free to use.

MP3 Audio Slicer

https://thedollarweb.com/tools/audio-slicer.html Free
+
What does the MP3 Audio Slicer do?
The tool allows users to upload MP3 files, select start and end times in seconds, and slice the audio into smaller segments directly in the browser.
Do I need to install software or upload files to a server?
No. All processing happens locally in the browser using the Web Audio API, so your files never leave your device.
How do I use the tool?
Simply drag and drop or upload an MP3 file, enter the desired start and end times, and click the slice button. A preview of the sliced audio will be available before downloading.
What format are the sliced files saved in?
Sliced segments are exported as WAV files, ensuring high quality and compatibility with most media players.
Is there a way to preview before downloading?
Yes. The app provides an integrated preview player so you can confirm the correct segment before saving.
Is this tool free to use?
Yes — the advanced in-browser audio slicing and conversion features are completely free to use.

Audio Converter

https://thedollarweb.com/tools/audio-converter.html Free
+
What does the Audio Converter do?
It converts audio files between formats — MP3, M4A, WAV, OGG, and FLAC out; practically anything in, including MP3, M4A, AAC, WAV, OGG, OPUS, FLAC, WMA, and AIFF. You can queue a whole batch, pick the quality, and download results one by one or as a single ZIP.
Can it turn a video into an MP3?
Yes — drop in an MP4, MOV, or WebM and it extracts the audio track to whatever format you choose. Because nothing uploads first, it's usually faster than "video to MP3" websites.
Is there a file-size limit?
No artificial one. The conversion runs on your own device using FFmpeg compiled to WebAssembly, so there's no server to meter you. The only practical limit is your browser's memory, which comfortably handles hours of audio.
What does the one-time engine download mean?
The first time you convert, your browser downloads the FFmpeg conversion engine (roughly 30 MB) and caches it for future visits. That download is the engine itself — your audio files are never uploaded anywhere.
Which format should I choose?
MP3 at 192 kbps plays everywhere and is the safe default. Use WAV for editing, FLAC for lossless archiving, M4A for Apple ecosystems, and OGG for web projects. The quality selector applies to lossy formats; WAV and FLAC are always full quality.
Are my recordings private?
Yes. Voice memos, meetings, and demos are read straight from your disk into the page, converted in your browser's memory, and saved back to your device. Nothing is sent to a server, and closing the tab clears everything.

Audio Merger

https://thedollarweb.com/tools/audio-merger.html Free
+
What does the Audio Merger do?
This tool merges multiple audio files into a single seamless track directly in your browser. You can trim segments, apply fade in/out effects, add crossfades between tracks, preview with an interactive waveform, and export to WAV format.
What file formats are supported?
Supported input formats include MP3, WAV, OGG, M4A, and other common audio formats. The merged output is exported as uncompressed WAV for maximum quality.
How do I trim and adjust tracks?
Each track includes editable fields for start time, end time, fade in duration, fade out duration, and gain. Set precise values in seconds to slice segments and control fading. Tracks can be reordered using up/down buttons or arrow keys.
What are crossfades and how do they work?
The global crossfade setting automatically overlaps consecutive tracks by your chosen duration in seconds. This creates smooth transitions by fading out the ending of one track while fading in the beginning of the next.
Can I preview before exporting?
Absolutely. The Preview button plays your merged audio in real-time with an interactive waveform display. Click anywhere on the waveform to jump to that position, and use the overlay controls to play or pause.
What audio settings can I customize?
Adjust project sample rate from 22050 to 96000 Hz (44100 recommended for compatibility), set a default crossfade duration in seconds, and configure headroom gain in decibels to reduce peak clipping when tracks overlap.
Does the waveform show playback position?
Yes. During preview, a yellow playhead moves across the waveform in real-time. Time displays show current position and total duration with millisecond precision.
Is this tool free to use?
Yes — advanced audio merging with precise trimming, fade controls, crossfade automation, interactive waveform preview, and browser-based WAV rendering is completely free to use.

Audio Transcriber

https://thedollarweb.com/tools/audio-transcriber.html Free
+
What does the Audio Transcriber do?
It takes any audio file — a voice memo, podcast, interview, lecture, or meeting recording — and turns the speech into editable text with timestamps. You can fix the wording, click any timestamp to jump to that moment in the audio, and export the result as a TXT, Markdown, DOCX, SRT, VTT, or JSON file.
Does my audio get uploaded to a server?
No. Decoding, transcription, editing, and export all run locally in your browser. The speech-to-text model is downloaded once from Hugging Face and cached by your browser; after that, nothing about your audio leaves your device.
What speech-to-text model does it use?
OpenAI's Whisper (MIT license), running in your browser via the @xenova/transformers library (Apache 2.0, Hugging Face) which wraps an ONNX build of the model. You can choose between tiny (~40 MB, fastest), base (~80 MB, default), and small (~250 MB, most accurate). The first run downloads the chosen model and caches it; subsequent runs are offline.
Which audio formats are supported?
Anything the Web Audio API can decode — typically MP3, WAV, M4A, AAC, OGG, FLAC, and WebM audio. The tool downsamples to 16 kHz mono in memory before transcription, which is what Whisper expects.
Can I transcribe in languages other than English?
Yes. Pick the multilingual base model from the model dropdown to transcribe French, Spanish, German, Italian, Portuguese, Dutch, Russian, Mandarin, Japanese, and dozens of other languages Whisper supports. The English-only models are smaller and a bit faster if you only need English.
How long can the audio be?
There's a 200 MB file size limit, which covers several hours of compressed audio. Transcription speed depends on the model and your hardware — expect roughly 0.3–1× real time on a modern laptop with the base model.
Can I edit the transcript before exporting?
Yes. Every cue appears in an editable list with its start/end timestamps. You can fix typos, correct mishears, delete cues, and click any timestamp to seek the audio player to that moment so you can re-listen to a tricky passage before editing.
What's the difference between the export formats?
TXT is plain concatenated text, ideal for notes. Markdown adds timestamp headers per cue. DOCX is a Microsoft Word document with a title and timestamped paragraphs. SRT and VTT are subtitle/caption formats that pair with video. JSON keeps the raw cue data with start/end times for downstream automation.
Is the Audio Transcriber free?
Yes, it's completely free to use with no sign-up required.

Baby Name Generator

https://thedollarweb.com/tools/baby-name-generator.html Free
+
What does the Baby Name Generator do?
It helps you find a baby name from a curated database of 1,000+ names, each tagged with its origin, meaning, style, and popularity. Filter by gender (boy, girl, or gender-neutral), origin, style (classic, modern, vintage, nature, biblical, mythological, royal, unique), popularity, first letter, syllable count, or even what the name means — then generate suggestions twelve at a time.
How does the last name preview work?
Type your last name into the optional field and every suggestion is shown as a full name. A flow check flags names whose ending sound runs into your surname's starting sound, notes the syllable rhythm, and the middle-name pairer screens the full initials so a shortlisted name never spells out something unfortunate as a monogram.
Can it suggest middle names too?
Yes. Every name card has a "Suggest middle names" button that proposes middles with a contrasting syllable pattern to the first and last name — the rhythm rule name consultants use — and you can shortlist a full first-middle pairing with one tap.
Where is my shortlist saved?
In your browser's local storage on this device. Nothing you type — your last name included — is ever uploaded. You can copy the shortlist as text for a group chat or print it as a clean list, and you can add a name of your own by hand (a family name, say) even if it isn't in the database. Premium members can optionally turn on cloud backup to sync their shortlist and vetoed names across devices; it's off by default and fully opt-in.
Can I stop a name from showing up again?
Yes — tap the ✕ on any name card and it's vetoed: it never appears in another shuffle, on any visit. The "Restore hidden" link shows your full veto list, where you can put a single name back in the pool or restore them all.
Where do the meanings and origins come from?
The database is hand-curated with each name's most widely accepted etymology across 30+ origins, from Irish and Hebrew to Japanese, Yoruba, and Hawaiian. Many names have several plausible histories; the tool carries the mainstream one.
Is the Baby Name Generator free?
Yes, it's completely free to use with no sign-up required.

Background Remover

https://thedollarweb.com/tools/background-remover.html Free
+
What does the Background Remover do?
Drop any photo and it produces a transparent-background PNG in seconds. It isolates the main subject — people, pets, products, objects — using an AI segmentation model, then lets you download the cutout or composite it onto a solid color.
Does my image get uploaded to a server?
No. Everything runs locally in your browser. The AI model and WebAssembly runtime are downloaded once from this site, cached by your browser, and then all inference happens on your device. Your image never leaves it.
What AI model does it use?
U²-Net (the lightweight "u2netp" variant), a well-known salient-object-segmentation model released under the Apache 2.0 license. Inference runs via ONNX Runtime Web (MIT-licensed, from Microsoft), compiled to WebAssembly. Both are fully open source and permit commercial use.
How long does it take?
Typically 0.5–2 seconds per image on a modern laptop after the first load. The very first image takes a few extra seconds while the ~4.5 MB model and ~11 MB runtime load and get cached; every subsequent image is near-instant.
What image sizes and formats work?
JPG, PNG, and WebP are all supported. The tool handles images up to around 4096×4096 comfortably. The model processes a 320×320 internal view of your image for speed, then scales the resulting mask back up with smoothing to your original resolution.
Can I replace the background with a solid color instead of transparency?
Yes. After the cutout is generated, pick any of the preset colors (white, black, teal, gold, deep blue, coral) or open the custom color picker to use a specific brand color. The preview updates instantly and the downloaded PNG matches what you see.
What kinds of images does it struggle with?
Hair flyaways, semi-transparent objects (glass, smoke), very busy backgrounds that blend into the subject, and tightly packed groups can produce rough edges. For those cases, upgrading your input lighting/contrast often helps more than the model can.
Is this tool free to use?
Yes — the Background Remover with no watermarks, no sign-up, and the full solid-color background option is completely free to use.

Base64 Encode / Decode

https://thedollarweb.com/tools/base64.html Free
+
What does the Base64 tool do?
It encodes text or files into Base64 and decodes Base64 back again. It's UTF-8 safe (emoji and accented or non-Latin characters work correctly), supports URL-safe Base64 and data-URI output, and can decode a Base64 string back into a downloadable file.
Is my data uploaded anywhere?
No. Everything is encoded and decoded in your browser, so you can safely handle tokens, keys, and other sensitive values without pasting them into a site that logs submissions.
What's URL-safe Base64 and a data URI?
URL-safe Base64 replaces the + and / characters with - and _ and drops padding, so it's safe in URLs, JWTs, and filenames. A data URI wraps the result as data:<type>;base64,… so you can paste it directly into HTML or CSS.
Can I encode an image or decode back to a file?
Yes. Use "Encode a file…" to turn any file into Base64 or a data URI. In Decode mode, paste a Base64 string or full data URI and click "Download decoded file" to get the original back — the file type is detected automatically when a data URI is provided.
Is the Base64 tool free?
Yes, it's completely free to use with no sign-up required.

Bayes' Theorem Visualizer

https://thedollarweb.com/tools/bayes-theorem-visualizer.html Free
+
What is the Bayes' Theorem Visualizer?
An interactive answer to the question that stumps almost everyone: "I tested positive — how likely is it real?" You set the base rate, the test's sensitivity, and its specificity, and a grid of 1,000 people shows you the answer: real cases in coral, false alarms in gold, with the formula printed underneath using your live numbers.
What is the false-positive paradox?
When a condition is rare, the healthy crowd is enormous, so even a tiny error rate produces more false alarms than there are real cases. The classic example: a disease affecting 1 in 100, tested at 90% sensitivity and 91% specificity, means a positive result is only about 9% likely to be real. Most people — including most doctors in published studies — guess close to 90%.
Why a grid of 1,000 people instead of the formula?
Because research shows people reason correctly with "natural frequencies" (9 real alarms out of 98 total) and badly with conditional probabilities. On the grid you can literally count the dots: the gold false alarms visibly outnumber the coral real catches. Once you've seen it as a crowd, the formula is just bookkeeping.
What are the scenario presets?
Four real-world settings with realistic numbers: rare disease screening (the classic 9% surprise), an airport watchlist that's 99% accurate yet produces ten false alarms per real hit, a workplace drug test, and a spam filter — where the 40% base rate flips the story and positives become trustworthy. Move any slider to switch to custom numbers.
What does "a second independent positive" mean?
Bayes' theorem chains: the answer after one positive becomes the starting point for the next test. The tool shows this — on the classic disease example, a second positive moves you from about 9% to about 50%. This is exactly why screening programs always confirm a positive with a second, different test before acting.
Does this relate to machine learning?
Directly. The headline number here is what ML practitioners call precision, and the paradox is why a fraud model or medical classifier with impressive accuracy can still bury its users in false alerts when the target is rare. Our ML Performance Metrics tool covers the same idea from the model-evaluation side.

Bill of Sale Generator

https://thedollarweb.com/tools/bill-of-sale.html Free
+
What does the Bill of Sale Generator do?
It builds a structured, legal-style bill of sale for private sales: cars, boats, motorcycles, trailers and RVs, firearms, horses and other animals, electronics, or anything else. You fill in the parties, the property with its identifying numbers, and the price; the generator writes the clauses — condition, seller certifications, odometer disclosure — and produces a clean PDF you can sign right in the browser.
Is the document legally valid?
A signed bill of sale is generally a valid record of a private sale, and this template includes the elements courts and DMVs look for, plus optional witness lines and a notary acknowledgment block. Requirements vary by state — a few require their own DMV form for vehicles, and firearm transfers are separately regulated — so check your state's rules. It's a template, not legal advice.
How do the signatures work?
Draw your signature with a mouse or finger, or type your name and it renders in a signature script; either way it's embedded into the PDF. If the buyer is with you, they sign in the second pad. If not, use "Send to buyer" — the message includes the PDF plus step-by-step instructions for counter-signing with the free PDF Signature tool on their own device.
What is the odometer disclosure?
Federal law requires the seller of a motor vehicle to disclose the mileage at transfer. For vehicles and motorcycles the generator adds the required statement with your reading and the correct certification: actual mileage, exceeds mechanical limits, or not actual (discrepancy).
Can I save more than one document?
Yes — the document picker at the top keeps multiple drafts, saved in your browser. Premium members can turn on cloud backup to sync saved documents (including signatures) across devices; it's off by default, opt-in, and reversible.
Is my sale information private?
Yes. Names, addresses, VINs, prices, and signatures stay in your browser, and the PDF is generated on your device. Nothing is uploaded.

Bingo Card Generator

https://thedollarweb.com/tools/bingo-card-generator.html Free
+
What does the Bingo Card Generator do?
It creates printable bingo cards — either classic 1–75 number bingo or custom word/picture bingo from a list you provide. Every card is shuffled independently, so no two players get the same board.
Can I make my own themed (word) bingo?
Yes. Switch to "Word / custom," paste your words or phrases one per line, and each card fills with a random selection. It's great for holidays, classrooms, baby showers, and meeting buzzword bingo.
How many words do I need for word bingo?
At least 24 with a free center space, or 25 without one. Adding more words increases the variety between cards.
How do I print the cards or save them as a PDF?
Click "Print / Save as PDF." The print view shows one clean card per page; choose your printer, or pick "Save as PDF" as the destination to keep a file.
Is it free and private?
Yes. It's completely free with no sign-up, and the cards (and any custom word list) are generated in your browser — nothing is uploaded.

BMI Calculator

https://thedollarweb.com/tools/bmi-calculator.html Free
+
What does the BMI Calculator do?
Enter your height and weight and it instantly calculates your Body Mass Index, shows which category it falls in (underweight, normal, overweight, or obese) on a color-coded scale, and tells you the healthy weight range for your height.
Does it support both metric and imperial units?
Yes. Switch between metric (kilograms and centimeters) and imperial (pounds, feet, and inches) with one tap — your entered values are converted automatically so the result stays consistent.
How is BMI calculated?
BMI is your weight divided by the square of your height: kilograms ÷ (meters × meters), or 703 × pounds ÷ (inches × inches) in imperial. The standard adult categories are: under 18.5 underweight, 18.5–24.9 normal, 25–29.9 overweight, and 30 or above obese.
Is my information uploaded anywhere?
No. The calculation happens entirely in your browser and nothing you enter is sent to a server or stored — your height and weight stay private.
Is BMI an accurate measure of health?
BMI is a quick screening tool, not a diagnosis. Because it uses only height and weight, it can over- or under-estimate body fat for very muscular people, older adults, and others, and it's intended for adults aged 20 and over. Always discuss your individual health with a qualified professional.
Is the BMI Calculator free?
Yes, it's completely free to use with no sign-up required.

Bracket Maker

https://thedollarweb.com/tools/bracket-maker.html Free
+
What does the Bracket Maker do?
It turns a list of 2–64 players or teams into a single-elimination tournament bracket. You can run the whole tournament on the page — click the winner of each matchup and they advance until a champion holds the trophy — then print the bracket or download it as a PNG.
What if my player count isn't 4, 8, 16, 32, or 64?
Any count from 2 to 64 works. The bracket rounds up to the next power of two and the top seeds get first-round byes automatically, exactly like real tournaments — with 13 players, the top 3 seeds skip round one.
How does seeding work?
"In list order" treats your first line as the #1 seed and uses classic tournament placement, so the top two seeds can only meet in the final. Choose "Shuffle" instead to draw the matchups completely at random — it re-draws every time you click Generate.
Can I change a winner after picking?
Yes — click the other name in that matchup. Any later-round picks that depended on the old winner are cleared automatically, and "Clear picks" resets the whole bracket without re-entering names.
How do I share or print the bracket?
The Print button prints just the bracket (no page clutter), and Download PNG saves a high-resolution image sized to your bracket — ready for the group chat, a slide, or the break-room wall.
Is my participant list private?
Yes. The bracket is generated entirely in your browser — names are never uploaded, stored, or seen by anyone else.

Budget Planner & Expense Tracker

https://thedollarweb.com/tools/budget-planner.html Free
+
What does the Budget Planner & Expense Tracker do?
It's a monthly budget with category limits and an expense log, minus the part every other budget app demands: a bank login. Set budgets per category, add expenses by hand or import your bank's CSV statement, and get progress bars, a safe-to-spend daily number, spending charts, subscription detection, and month-over-month insights — all computed in your browser.
How does the bank statement import work without connecting my bank?
Every bank and credit card lets you download transactions as a CSV file. Drop that file into the import box: the planner detects which columns hold the date, description, and amount, handles both sign conventions, separates purchases from income, and shows a preview before anything is saved. The file is read entirely by your browser and never uploaded.
Will re-importing the same statement create duplicates?
No. Rows matching a transaction you already have (same date, description, and amount) are flagged as duplicates and skipped automatically, so re-dropping last month's file is always safe.
How are transactions categorized?
A built-in merchant dictionary recognizes common charges (coffee shops to Dining, gas stations to Transport, streaming to Subscriptions). When you correct a category, the planner offers to remember that merchant, and your rule applies to everything you add or import afterward. Rules live in your browser.
What is the safe-to-spend number?
What's left of your total monthly budget divided by the days remaining — one honest daily number that updates with every expense. It's the single most behavior-changing stat in budgeting.
Can it find subscriptions I forgot about?
Yes. The recurring-charge radar flags merchants that charge a similar amount in consecutive months and totals your subscriptions per month — frequently an eye-opening figure.
Where is my financial data stored?
In your browser's local storage on this device — nothing is uploaded, and there is no account or bank connection. Premium members can optionally turn on cloud backup to sync their budget across devices; it's off by default, opt-in, and reversible.

Business Card Designer

https://thedollarweb.com/tools/business-card.html Free
+
What does the Business Card Designer do?
It lets you design a professional business card in your browser with a live preview, then export print-ready files — single PNGs at 300 DPI, a PDF with front and back pages, a 10-up sheet on US Letter for self-printing, or a vCard (.vcf) contact file.
What templates and themes are available?
12 distinct front layouts — Modern, Minimal, Classic, Bold, Creative, Corporate, Tech, Elegant, Gradient, Photo, Dark, and Split — each paired with a generic back design (logo, QR, tagline, or solid). You can choose from 26 color themes or pick a custom accent color, and select separate fonts for headlines and body text.
What contact details can I put on the card?
Full name, pronouns, title, company, tagline, phone, email, website, LinkedIn handle, and a two-line address. You can also upload a headshot (circle, square, or hidden), a company logo for the back, and a signature image.
Is the QR code required?
No — the QR code is an optional add-on. When enabled, you can choose whether it scans to save your contact (vCard format) or opens a website URL you specify. You can also make the QR background transparent so the card's background shows through instead of a white pad.
Are the exports actually print-ready?
Yes. The card is rendered at the standard US business card size (3.5" × 2", 1050 × 600 px at 300 DPI). The 10-up PDF lays out 10 cards on US Letter with the backs mirrored so a duplex print produces correctly aligned front/back cards. Choose sharp or rounded corners depending on your print vendor.
Does my data leave my browser?
No. All rendering, QR generation, and PDF/PNG export runs entirely in your browser. Your contact details, headshot, logo, and signature are never uploaded anywhere.
Can I design in portrait orientation?
Yes. Toggle the orientation control to switch between landscape (3.5" × 2") and portrait (2" × 3.5") — the templates adapt to both.
Is this tool free to use?
Yes — the Business Card Designer with all 12 templates, 26 themes, QR options, and print-ready exports is completely free to use.

Bulk File Renamer

https://thedollarweb.com/tools/bulk-renamer.html Free
+
What does the Bulk File Renamer do?
This tool allows users to upload multiple files and instantly rename them in bulk using custom prefixes, suffixes, or sequential numbering.
How do I upload files?
You can drag and drop files into the upload zone or click to browse. The tool supports multiple files of any type, including documents, images, and text files.
What renaming options are available?
Options include adding a prefix, adding a suffix, combining prefixes or suffixes with sequential numbering, or renaming files with only sequential numbering. Number formats can be customized (1, 01, 001).
Can I reorder my files?
Yes. Files can be rearranged by drag-and-drop, and the sequential numbering will follow the custom order you set.
How do I download renamed files?
You can download renamed files individually or export all renamed files together as a ZIP archive.
Is this tool free to use?
Yes — advanced batch renaming, drag-and-drop reordering, and bulk ZIP export are completely free to use.

Printable Calendar Maker

https://thedollarweb.com/tools/calendar-maker.html Free
+
What does the Printable Calendar Maker do?
It builds a clean, printable calendar — a single month or a whole year — with your own events, holidays, photos, and colors. You can export a print-ready PDF (US Letter or A4, portrait or landscape) or a PNG image, all from your browser.
How do I add my own events and holidays?
Type one event per line in the events box. Use a full date like 2026-07-22: Dentist for a one-off, or a month-day like 12-25: Christmas for something that repeats every year, such as birthdays and holidays. They appear on the matching days automatically.
Can I make a calendar for the whole year?
Yes. The "Full year" button generates a 12-page PDF — one month per page — in your chosen paper size, with your events placed on the right dates throughout the year.
Are my events or photos uploaded anywhere?
No. The calendar is drawn entirely on a canvas in your browser, and the PDF is assembled locally. Your events, appointments, and any photo you add never leave your device.
Will it print clearly?
Yes — the calendar renders at high resolution and is sized to fill the page, so dates and text stay sharp when printed. You can start the week on Sunday or Monday and optionally shade the weekends.
Is the Printable Calendar Maker free?
Yes, it's completely free to use with no sign-up required.

Calorie & TDEE Calculator

https://thedollarweb.com/tools/calorie-calculator.html Free
+
What does the Calorie & TDEE Calculator do?
It estimates your BMR (the calories your body burns at complete rest) and your TDEE — total daily energy expenditure, also called maintenance calories — from your sex, age, height, weight, and activity level. It then shows daily calorie targets for losing or gaining weight at mild, standard, and aggressive paces, and breaks any target into protein, carbs, and fat grams.
Which formula does it use?
Mifflin-St Jeor by default — the equation research has found most accurate for the general population and the one dietitians typically use. If you enter your body fat percentage, it automatically switches to Katch-McArdle, which calculates from lean body mass and is more accurate for lean, muscular people.
Is my health data uploaded anywhere?
No. Your age, weight, and body composition are health data, and the entire calculation runs on your device — no lead-capture form, no email gate, no ad trackers profiling your fitness goals. Your inputs save only to your own browser so they're prefilled next visit.
How many calories should I eat to lose weight?
A common, sustainable approach is 500 calories under your TDEE, which works out to roughly 1 lb (0.45 kg) per week, since a pound of body fat stores about 3,500 calories. The goals table shows mild (−250), standard (−500), and aggressive (−1,000) options with their expected pace — and flags any target that falls below the generally recommended minimums (about 1,500 kcal for men, 1,200 for women).
How accurate is a TDEE calculator?
It's a well-tested population estimate, typically within about 10% — but individuals vary, and the biggest error source is overestimating your activity level (a desk job plus a few gym sessions is "Light" to "Moderate," not "Very active"). Best practice: pick honestly, eat at the number for two or three weeks, and adjust based on what the scale actually does.
What are the macro presets?
Click any goal row and choose a split: Balanced (30% protein / 40% carbs / 30% fat), High protein (40/30/30 — popular when cutting because protein preserves muscle and satiety), or Lower carb (30/20/50). Protein and carbs count 4 calories per gram, fat 9. Total calories drive weight change; macros shape how you feel.
Is this medical advice?
No — these are estimates from population formulas, meant as a starting point. Talk to a doctor or registered dietitian before major dietary changes, especially if you have a medical condition, are pregnant, or are under 18.

Case Converter

https://thedollarweb.com/tools/case-converter.html Free
+
What does the Case Converter do?
Paste any text and it shows that text in every common case at once — UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, dot.case, a URL slug, plus alternating and inverse case. Each result has its own copy button.
Is my text uploaded anywhere?
No. The conversions happen entirely in your browser as you type — nothing is uploaded or stored.
What's the difference between Title Case and Sentence case?
Title Case capitalizes the first letter of every word (good for headings), while Sentence case capitalizes only the first letter of each sentence and lowercases the rest (like normal prose).
Can it create a URL slug from a sentence?
Yes — the "Slug" output lowercases your text, joins words with hyphens, and strips punctuation, giving you a clean, link-friendly string for URLs and file names.
Is the Case Converter free?
Yes, it's completely free to use with no sign-up required.

Color Blindness Simulator

https://thedollarweb.com/tools/color-blindness-simulator.html Free
+
What does the Color Blindness Simulator do?
It shows any image the way people with color vision deficiency see it. Drop in a design, chart, map, or photo (Ctrl+V paste works), pick from eight vision types, and drag the split slider to compare original vs. simulated. A grid view shows all eight types at once, and you can export the simulated view or a labeled side-by-side PNG.
Which types of color blindness does it simulate?
Deuteranopia and deuteranomaly (green-blind/weak — deuteranomaly alone affects about 5% of men), protanopia and protanomaly (red-blind/weak), tritanopia and tritanomaly (blue-blind/weak, rare), and achromatopsia/achromatomaly (complete or partial absence of color). Each type in the picker shows a small palette strip previewing how red, green, blue, and yellow shift.
How accurate is the simulation?
It uses the Machado, Oliveira & Fernandes (2009) matrices — a peer-reviewed physiological model that's the standard for this task — and applies them in linear RGB after undoing the image's gamma encoding, a correctness step many quick simulators skip. The severity slider blends toward normal vision to approximate milder cases. It shows the perceptual result faithfully; it can't convey the lived experience.
Why should designers care?
About 1 in 12 men and 1 in 200 women have some color vision deficiency — statistically, several of your users. If your chart's meaning lives entirely in red-vs-green, or your form marks errors only with color, part of your audience can't see it. Two minutes here catches those problems before your users do.
How do I fix problems the simulator reveals?
Add a second channel besides hue: labels, icons, patterns, dashed vs. solid lines, or clear lightness differences. The achromatopsia view doubles as a pure contrast test — if elements are distinguishable there, they're distinguishable to everyone. Export the side-by-side PNG to make the case in a design review.
Is my image uploaded anywhere?
No — the entire simulation is canvas math on your own device, which matters when the image is an unreleased product design or confidential dashboard. There's also a built-in sample scene (traffic lights, status dots, chart lines, a rainbow) so you can explore without loading anything.
Is this tool free?
Yes — free, no sign-up, unlimited images and exports.

Color Converter

https://thedollarweb.com/tools/color-converter.html Free
+
What does the Color Converter do?
It converts a color between HEX, RGB, HSL, HSV/HSB, and CMYK all at once. Change the color any way you like — type a HEX code, edit the R/G/B or H/S/L channels, drag the sliders, or use the picker — and every format updates instantly, ready to copy.
Can I convert HEX to RGB and RGB to HEX?
Yes, in both directions, along with HSL, HSV, and CMYK. Each output has a one-click Copy button so you can grab the exact CSS value you need.
Does it support transparency (alpha)?
Yes. Set the alpha slider to get rgba(), hsla(), and 8-digit HEX, with the color previewed over a checkerboard so you can see the transparency.
What is the contrast check?
It tells you whether black or white text reads best on the current color and shows the WCAG contrast ratio and grade (AA/AAA), which is handy for accessible design.
Is it free?
Yes, completely free with no sign-up, and it runs entirely in your browser — nothing is uploaded.

Color Palette Generator

https://thedollarweb.com/tools/color-palette.html Free
+
What does the Color Palette Generator do?
This tool lets you generate stunning color palettes by selecting a base color and applying different harmony rules like analogous, complementary, triadic, tetradic, monochromatic, or split-complement.
How do I get started?
Choose a preset theme (e.g., Ocean Blue, Sunset Coral, Golden Hour) or click a color swatch to set your base color. You can also manually pick a custom base color using the built-in color picker.
What kind of palettes can I make?
You can instantly generate palettes with multiple harmonious colors. Each swatch includes its HEX code and an easy-to-read color name. Clicking a swatch copies its color code to your clipboard for quick use.
Can I export my palettes?
Yes. You can copy palettes as CSS variables or download them as a JSON file for reuse in design projects or coding workflows.
Is this tool free?
Yes, the Color Palette Generator is completely free to use with no restrictions.

Compound Interest Calculator

https://thedollarweb.com/tools/compound-interest-calculator.html Free
+
What does the Compound Interest Calculator do?
It projects how money grows: enter a starting amount, a regular contribution (monthly or yearly), an interest rate, a compounding frequency, and a number of years. You get the future balance, a breakdown of what you contributed versus what interest earned, a stacked year-by-year chart, and a full yearly table.
How is the growth calculated?
Your rate and compounding choice are converted to an effective annual rate — EAR = (1 + r/n)ⁿ − 1 — and the balance is simulated period by period, with contributions added at the end of each period (the standard convention). You can check any year in the table against another calculator or your own statements.
What's the "annual increase in contribution" option?
It models raising your savings each year — for example 3% with each pay raise. Even a small annual step-up compounds dramatically over decades, and this option lets you see exactly how much.
What rate should I use?
That's your planning assumption, not ours: people commonly model long-run averages like 6–8% for diversified stock funds or 4–5% for conservative mixes. Real returns vary year to year — a fixed rate is a simplification, and the calculator says so right under the results. It's for education and planning, not financial advice.
Does it account for inflation or taxes?
No — results are in nominal dollars, before taxes and fees. For a rough "today's dollars" view, use a real rate: your expected return minus expected inflation.
Are my numbers private?
Completely. How much you have and save is nobody's business — the math runs in your browser, nothing is uploaded, and your inputs are remembered only locally on your own device.

Consulting Estimate Generator

https://thedollarweb.com/tools/consulting-estimate-generator.html Free
+
What does the Consulting Estimate Generator do?
This tool helps consultants and freelancers quickly build professional project estimates. Users can enter project details, client and company information, hourly rates, and project hours to generate an organized estimate.
How do I add project line items?
You can create multiple line items with descriptions, hours, and detailed explanations for each task. The app automatically numbers and calculates the total hours and costs.
Does it check for errors?
Yes. The tool provides a warning if the total project hours entered do not match the sum of the line item hours, ensuring accuracy.
Can I download the estimate?
Yes. After generating your estimate, you can download it as a professionally formatted PDF that includes project details, itemized costs, a summary, and customizable footnotes.
Is the tool free to use?
Yes, the Consulting Estimate Generator is fully free and does not require a subscription.

Cover Letter Generator

https://thedollarweb.com/tools/cover-letter-generator.html Free
+
What does the Cover Letter Generator do?
It removes the blank page. Fill in who you are, what the job is, and a couple of your strengths, pick one of five proven letter structures, and click "Write my letter" — you get a complete, professional draft in a live letter preview. Then edit any word of it, and download a clean PDF, print it, or copy plain text for application portals.
Is it an AI writer?
Deliberately not. Recruiters can spot AI-inflated letters instantly. These are carefully written human templates — short, direct, and specific — that your own details get slotted into. The editable body is where you add the one thing templates can't: something concrete about you and the company.
What are the five templates?
Standard (experienced professional), Enthusiastic (leads with why this company), Career changer (frames experience as transferable), Entry level / new grad (honest early-career letter that shows initiative), and Referral (opens with the person who recommended you — the strongest opener there is).
Is my information uploaded anywhere?
No — and this matters more here than almost anywhere: a job search is one of the most sensitive things you do online, especially while employed. Everything, including the PDF generation, happens in your browser. Your entries save only to your own browser so you can come back and adapt the letter for the next application.
How do I paste the letter into an application form?
Use "Copy as text" — it produces the full letter as clean plain text with proper paragraph breaks, ready for any portal text box. The Word & Character Counter tool can check it fits the portal's length limit.
Any tips for a stronger letter?
Find a real hiring manager name ("Dear Ms. Rivera" beats "Dear Hiring Manager"), fill in the one-line achievement field with a number if possible, keep it to one page, and always edit the draft — a specific detail about the company or the problem you'd start on is what gets interviews.
Can I make a matching resume?
Yes — the Resume Builder on this site works the same way (free, private, live preview, PDF export), and the PDF Combiner can merge your resume and cover letter into a single file when a posting asks for one document.

Crossword Puzzle Maker

https://thedollarweb.com/tools/crossword-maker.html Free
+
What does the Crossword Puzzle Maker do?
It turns your own words and clues into a real interlocking crossword. Type entries as "word : clue", click build, and the layout engine weaves the grid automatically with standard numbered Across and Down clues. You can print it or download a Letter-size PDF with a separate answer-key page.
How does the automatic layout work?
The engine tries thousands of arrangements, connecting words through shared letters while following real crossword rules (no accidental side-by-side words), and keeps the layout that places the most words with the most intersections in the tightest grid. "Try another layout" re-rolls for a different shape with the same words.
What if a word can't be connected?
The tool tells you which words couldn't be woven in rather than silently dropping them. Themed word sets connect much better than random ones — and swapping a stubborn word for a synonym with common letters (E, S, T, A, R) usually fixes it.
How many words can I use?
Two to thirty entries, with answers from 2 to 16 letters. Multi-word answers work too — spaces and punctuation are removed automatically, so "New York" becomes NEWYORK in the grid.
Is there an answer key?
Yes, two ways: a "Show answers on screen" toggle for checking your puzzle while you build, and an optional answer-key page in the PDF — it's a separate page, so you can hand out page one and keep page two. The on-screen answers are never included when you print the puzzle itself.
Do I have to write my own words?
No — there are ready-made themed packs (Ocean Life, Space, In the Kitchen, World Capitals) you can load with one click and then edit however you like.
Are my words and clues private?
Yes. The puzzle is generated entirely in your browser — classroom material, family names, and inside jokes are never uploaded or stored on a server. Your work also autosaves locally so you can come back and finish later.

CSS Box Shadow Generator

https://thedollarweb.com/tools/box-shadow-generator.html Free
+
What does the CSS Box Shadow Generator do?
It lets you design a CSS box-shadow visually — drag sliders for offset, blur, spread, color, and opacity with a live preview — then copy the exact box-shadow CSS to paste into your stylesheet.
Can I create inset (inner) shadows?
Yes. Tick the "Inset" option to turn any shadow into an inner shadow that looks pressed-in rather than raised.
Can I layer multiple shadows?
Yes — add several shadow layers and they stack into one declaration separated by commas. Layering two or three soft, low-opacity shadows is the trick behind realistic depth.
How is the color and opacity handled?
Pick a color (or type a hex) and set opacity with its own slider; the CSS is emitted as rgba() so the transparency is independent of the color. You can also change the preview box's color and corner radius.
Is it free?
Yes, completely free with no sign-up, and it runs entirely in your browser — your last design is even remembered locally for next time.

CSS Gradient Generator

https://thedollarweb.com/tools/css-gradient-generator.html Free
+
What does the CSS Gradient Generator do?
It lets you design a gradient visually — pick the type, colors, angle, and position — with a live preview, then copy the ready-to-use CSS for your background.
What gradient types are supported?
Linear (with an adjustable angle and one-tap directions), radial (circle or ellipse, positioned anywhere), and conic (a swept gradient that sweeps around a center point).
Can I use more than two colors?
Yes — add as many color stops as you like, set each stop's position with a slider, type an exact hex value, and remove any you don't need. Two stops at the same position create a hard edge for stripes.
How do I get the code?
Click "Copy CSS" to copy the full background declaration, then paste it into your stylesheet. Your last gradient is also remembered in your browser for next time.
Is it free?
Yes, it's completely free with no sign-up, and it runs entirely in your browser — nothing is uploaded.

Date Calculator

https://thedollarweb.com/tools/date-calculator.html Free
+
What does the Date Calculator do?
Two things: it counts the time between two dates — as years, months, and days plus totals like total days, weeks, and business days — and it adds or subtracts days, weeks, months, and years from a date to find a new date.
How do I find how many days until a date?
On the "Days between dates" tab, set the start date to today (there's a "Today" shortcut) and the end date to your target date — the day count appears instantly, along with a full breakdown.
Can it count business days?
Yes. The difference view shows how many weekdays (Mon–Fri) and weekend days fall between the two dates, and the add/subtract view has an option to count the days you add as business days only.
What's the "include the end day" option?
By default the difference counts whole days between the dates. Tick "Include the end day" to count both endpoints — handy for things like a length of stay where the first and last day both count.
Is it accurate with leap years and time zones?
Yes. It uses calendar dates only and handles leap years and varying month lengths, so time zones and daylight saving don't affect the result. It's free and runs entirely in your browser.

Debt Payoff Calculator

https://thedollarweb.com/tools/debt-payoff-calculator.html Free
+
What does the Debt Payoff Calculator do?
List each debt with its balance, APR, and minimum payment, add whatever extra you can pay per month, and it simulates your payoff month by month under three approaches — minimums only, snowball, and avalanche — showing your debt-free date, total interest, interest and months saved, each strategy's payoff order, and a chart of your balance falling over time.
What's the difference between snowball and avalanche?
Snowball pays extra toward the smallest balance first — quick early wins that keep people motivated. Avalanche pays extra toward the highest interest rate first — mathematically optimal, always the cheapest or tied. The tool shows both with a 🏆 on the cheaper one; when the difference is small (it often is), it says so honestly and tells you to pick whichever you'll stick to.
What is the rollover (the actual "snowball effect")?
When a debt is paid off, its minimum payment doesn't return to your pocket — the simulation rolls it onto the next target debt, on top of your extra payment. That's why payoff accelerates: the last debt gets attacked by every freed-up minimum plus the extra.
Why does it say my balance will grow forever?
If a minimum payment is smaller than a debt's monthly interest, the balance rises even while you pay — a real and common trap. The tool flags that debt in red instead of pretending. Fixes: a larger payment, or a lower rate via a balance transfer or consolidation loan (model it by editing the APR).
How accurate is the simulation?
It assumes fixed APRs, fixed minimum payments, and monthly compounding. Real credit cards recalculate minimums as balances fall, which usually makes real payoff slightly faster than shown if you keep your payment constant. Treat it as a solid planning estimate, not financial advice.
Is my financial information uploaded?
No. Debt balances are among the most sensitive numbers a person has, and most debt calculators online are lead-generation for consolidation companies. This one runs entirely in your browser — no upload, no email gate, and your entries save only to your own device.
Is this tool free?
Yes — completely free, no sign-up, unlimited debts and scenarios.

Decision Dice

https://thedollarweb.com/tools/decision-dice.html Free
+
What is Decision Dice?
A decision maker where the odds are yours to set. Add options, give each a weight — pizza 3, tacos 2, salad 1 — see the exact percentage chance for every choice, and roll an animated die to make the call. Roll one at a time with sound and confetti, or ×10 / ×100 for bulk decisions.
How do weights work?
Weight is how many "sides of the die" an option gets. Weights of 3 and 1 make a four-sided die where the first option covers three sides — a 75% chance. The live percentage next to each option always shows the current odds, and setting a weight to 0 benches an option without deleting it.
Is the roll actually fair?
Yes, and you can check for yourself: every roll draws from your browser's crypto.getRandomValues — the cryptographically secure generator used for encryption keys — and the stats panel plots each option's observed share against a tick at its expected odds. Roll a few hundred times and watch the bars converge on the ticks.
How is this different from the Name Selector wheel?
The Name Selector gives every entry an equal chance — perfect for raffles and picking students. Decision Dice is for when the odds shouldn't be equal: weighted choices, custom dice, and probability you control.
Does it save my options?
Yes — your options, weights, and roll history are remembered locally in your browser, and only there. Nothing is uploaded, and the reset button clears the stats whenever you want a fresh start.
Is it free?
Completely free, no sign-up, and it works offline once loaded.

Decision Tree Visualizer

https://thedollarweb.com/tools/decision-tree-visualizer.html Free
+
What is the Decision Tree Visualizer?
An interactive lesson in the most explainable model in machine learning. A real decision tree trains live on 2D data, and you see the same model two ways at once: the flowchart of yes/no questions it learned, and the map of rectangular regions those questions carve out of the plane. Every slider change retrains it instantly.
Is this a real algorithm or a canned animation?
A real one. It runs CART, the classic tree-growing algorithm: at every node it tries every possible split on both features, keeps the one that leaves the purest groups by Gini impurity, and recurses until it hits your depth limit. The questions in the flowchart are genuinely discovered from the data each time.
How does it show overfitting?
Set label noise to 20% and slide depth to 8. Training accuracy climbs toward 100% while test accuracy drops, and the map fills with tiny rectangles carved around single mislabeled points — memorization you can literally see. Bring the depth back down and the test score recovers. It's the same lesson as our ML Overfitting Simulator, drawn with boxes instead of curves.
What are the three data patterns for?
Each teaches one idea. Two groups shows a case where a single question is nearly perfect. The checkerboard is unsolvable at depth 1 but easy at depth 2, showing why depth matters. The diagonal reveals the tree family's signature limitation: trees can only ask about one feature at a time, so they approximate a slanted boundary with a staircase of little rectangles.
What do train and test accuracy mean?
The tree learns from 150 training points (the solid dots) and is then graded on 100 test points it never saw (the rings). Training accuracy tells you how well it memorized; test accuracy tells you how well it actually generalizes. The gap between them is the whole overfitting story.
Why should I care about decision trees in 2026?
Because they're the building block of the models that dominate real-world tabular data: random forests average hundreds of trees, and gradient boosting (XGBoost, LightGBM) stacks them. Understand one tree and those famous methods stop being magic. Single trees are also still used directly wherever a model must be explainable to a regulator or a customer.
Is it free and private?
Completely free, no sign-up. Everything — data generation, training, drawing — happens in your browser. Nothing is uploaded anywhere.

Diff Checker

https://thedollarweb.com/tools/diff-checker.html Free
+
What does the Diff Checker do?
Paste an original and a changed version of any text and it highlights exactly what differs — added, removed, and changed lines, with the specific words that changed highlighted inside each modified line. View it side-by-side or as a single inline stream with + and − markers.
Is my text uploaded anywhere?
No. The comparison runs entirely in your browser using a longest-common-subsequence algorithm. Nothing is uploaded or logged, so even sensitive redlines and config changes stay private.
Can it ignore formatting differences?
Yes. Toggle "Ignore case" to treat capitalization as equal, "Ignore whitespace" to focus on real content changes rather than indentation or spacing, and "Ignore blank lines" to skip empty-line noise.
What can I compare?
Any text: two drafts of an article or contract, two config or log files, code snippets, or a copy-paste you want to verify against the original. It works line by line, so it handles everything from a sentence to thousands of lines.
Is the Diff Checker free?
Yes, it's completely free to use with no sign-up required.

Distribution Generator & Visualizer

https://thedollarweb.com/tools/distribution-generator.html Free
+
What does the Distribution Generator do?
Pick a probability distribution, set its parameters, and it draws thousands of random numbers from it and plots them as a histogram with the exact theoretical curve overlaid — the density (PDF) for continuous distributions or the probability mass (PMF) for discrete ones.
Which distributions are supported?
Over 25, including normal, uniform, exponential, log-normal, gamma, beta, chi-squared, Student's t, Cauchy, Laplace, logistic, Weibull, Pareto, Rayleigh, Gumbel, triangular, F, Maxwell–Boltzmann and half-normal, plus discrete ones: Bernoulli, binomial, Poisson, geometric, negative binomial, discrete uniform, and hypergeometric.
Can I change the parameters and sample size?
Yes — each distribution has the appropriate parameters with sliders and exact value boxes, and the chart updates live. Set how many samples to draw and click Resample to see fresh random data.
Can I export the data or chart?
Yes. Download the generated numbers as a CSV, or save the chart as a PNG. A summary of mean, standard deviation, min, median, and max updates with every sample.
Is it free and private?
Yes. It's completely free with no sign-up, and all the sampling and plotting happen in your browser — nothing is uploaded.

Event Ticket & Badge Maker

https://thedollarweb.com/tools/ticket-badge-maker.html Free
+
What does the Event Ticket & Badge Maker do?
It designs event tickets and wearable name badges, each with a scannable QR code for check-in, and can generate an entire guest list at once. You get a print-ready PDF (laid out several per page with cut guides), a ZIP of individual PNGs, or a single PNG.
How do I make one for every guest?
Paste your guest list into the box, one per line as Name, detail — where the detail is a seat/table for tickets or a role/company for badges. The tool builds one ticket or badge per line, automatically numbered with your chosen prefix.
What goes in the QR code?
Whatever you choose. By default it encodes the guest's name and ticket number, but you can use a template with {name}, {num}, {detail}, and {event} — for example a check-in URL like https://myevent.com/checkin?t={num}. Any standard QR scanner or phone camera can read it.
Is my guest list uploaded anywhere?
No. Everything — names, details, QR codes, and the finished PDF — is generated on your own device. Nothing is sent to a server, which matters when your file is a list of attendees.
Will the tickets print correctly?
Yes. Tickets print three to a page and badges print at a wearable size several to a page, both with light cut lines, on US Letter or A4. Everything renders at high resolution so the QR codes scan reliably.
Is the Event Ticket & Badge Maker free?
Yes, it's completely free with no sign-up and no per-ticket fee.

EXIF Metadata Scrubber

https://thedollarweb.com/tools/exif-scrubber.html Free
+
What is EXIF metadata and why remove it?
EXIF is hidden data your camera or phone bakes into a photo — often the exact GPS coordinates where it was taken, plus the date, device model, and editing software. When you upload or send the picture, that data can travel with it. Removing it protects your location and identity before you share.
Does it upload my photos?
No. Both reading the metadata and stripping it happen entirely in your browser. Your photos never leave your device — which is the whole point of a privacy tool.
Will stripping metadata reduce image quality?
No. For JPG, PNG, and WebP the metadata segments are removed without touching the compressed image data, so there's zero quality loss and the file usually gets slightly smaller. Your ICC color profile is preserved so colors look identical. Other formats fall back to a clean re-encode.
Can I see what's in my photo before removing it?
Yes. Each photo shows chips for GPS location, camera, date, software, and XMP/IPTC, and you can expand it to see the details — including a map link for the exact coordinates. Then download a cleaned copy or grab the whole batch as a ZIP.
Is the EXIF Metadata Scrubber free?
Yes, it's completely free to use with no sign-up required.

Expense Report Generator

https://thedollarweb.com/tools/expense-report.html Free
+
What does the Expense Report Generator do?
This tool allows users to create professional expense reports by entering personal details, categorizing expenses, and attaching receipts. It organizes information into a clear structure and calculates totals automatically.
How do I add expenses?
You can add multiple expense items, each with its own amount, description, and optional sub-items for breaking costs down further. Notes can also be added for context.
Does it support receipt uploads?
Yes. You can upload image or PDF receipts for each expense item. Uploaded images are previewed in the tool, while PDFs are listed by filename.
What if totals don't match sub-items?
The tool displays a warning message when the total amount of an expense item doesn't align with the sum of its sub-items, helping ensure accuracy.
Can I export my report?
Yes. With one click, you can generate a well-formatted PDF report that includes all expense details, sub-items, receipts, and a cover page.
Is this tool free?
Yes, the Expense Report Generator is completely free to use with no subscription required.

File to PDF Converter

https://thedollarweb.com/tools/file-to-pdf.html Free
+
What does the File to PDF Converter do?
This tool converts common file formats—including PNG, JPG, JPEG, TXT, and DOCX—into high-quality PDF documents.
How do I use the tool?
Simply drag and drop or upload a file, review the preview, and click "Convert to PDF." You can also set a custom PDF filename.
Can I add extra content to my PDF?
Yes. You can insert custom text blocks, including headers, footers, and watermarks. Each block supports choosing text color and placement (top, middle, bottom, left, center, right).
Does it work with DOCX files?
Yes. The tool uses a built-in DOCX parser to display and convert Word documents accurately into PDFs.
Can I preview before converting?
Absolutely. Uploaded files are displayed in a live preview, and any added text blocks are shown in position, so you know exactly how the final PDF will look.
Is this tool free?
Yes, the File to PDF Converter is completely free to use with no subscription required.

File Zipper

https://thedollarweb.com/tools/file-zipper.html Free
+
What does the File Zipper do?
The tool lets you compress multiple files into a single ZIP archive directly in your browser. It provides live stats for original size, compressed size, and compression ratio.
How do I add files?
You can drag and drop files into the upload zone or browse your device. Multiple files of any type are supported, and duplicates are automatically renamed.
Does it work offline or upload files to a server?
All compression happens locally in your browser using JSZip. Your files never leave your device.
Can I remove or reorder files before zipping?
Yes. Files can be removed individually from the list before creating the ZIP archive.
Does it check email attachment limits?
Yes. The tool displays compatibility with Gmail (25MB), Outlook (20MB), and Yahoo Mail (25MB) so you know whether your ZIP file can be emailed.
What is the output?
A ready-to-download ZIP file named either after the single file inside or, for multiple files, stamped with the current date.
Is this tool free?
Yes, the File Zipper is completely free to use with no subscription required.

Freelance Rate Calculator

https://thedollarweb.com/tools/freelance-rate-calculator.html Free
+
What does the Freelance Rate Calculator do?
It answers "what should I charge?" with honest math. Enter your target income, business expenses, weeks off, hours worked, and — critically — the percentage of your hours that are actually billable, and it produces an hourly rate (rounded up to the next $5), a day rate, and a week rate, with a full breakdown of where the number comes from.
Why can't I just divide my old salary by 2,080 hours?
Because that's how freelancers accidentally take a 40% pay cut. A salary bundles benefits, employer-side taxes, and paid vacation that an hourly rate must buy separately — and a freelancer's week has far fewer billable hours than an employee's has paid ones. Proposals, marketing, admin, and email don't bill; most established freelancers bill only 50–60% of the hours they work.
What is the "benefits & self-employment uplift"?
A rule-of-thumb 25–35% added on top of your target income to cover what an employer normally funds: health insurance, retirement contributions, employer-side payroll taxes, and paid leave. It's a planning stand-in, not tax advice — actual treatment varies by country and setup.
What's the sensitivity table for?
Every rate formula lives or dies on the billable-hours guess, so instead of hiding it, the table shows your required rate at 15, 20, 25, and 30 billable hours per week — with your own assumption highlighted. If your plan only works at 30 billable hours (a level most solo freelancers never sustain), you'll see it before your bank account does.
What does the current-rate comparison show?
Enter what you charge today and it computes the salary-equivalent that rate actually pays you — your billings minus expenses, deflated by the benefits uplift. For many freelancers this number is the wake-up call that starts the rate-raise conversation.
Is the result what I should quote clients?
It's your floor — the rate that hits your income target at your real capacity. Expertise, speed, and niche demand belong on top of it, and value-based or project pricing can beat hourly entirely. Use the copy-summary button to keep the math handy for negotiations.
Are my income numbers private?
Completely. Everything computes in your browser, and your inputs save only to your own device — no email gate, no lead capture, no marketing database learning your income goals.

GPA & Final Grade Calculator

https://thedollarweb.com/tools/gpa-calculator.html Free
+
What does the GPA & Final Grade Calculator do?
Two student essentials on one page. The GPA tab calculates your grade point average on the standard 4.0 scale from your courses, credits, and letter grades — with optional weighted (Honors/AP/IB) scoring and cumulative GPA. The second tab answers "what do I need on the final?" — enter your current grade, your target, and the final's weight, and it shows the exact score required, plus a table of what you'd need for every letter-grade cutoff.
How is GPA calculated?
Each course's grade points (A = 4.0, A− = 3.7, B+ = 3.3, and so on down to F = 0.0) are multiplied by its credit hours, summed, and divided by total credits. That's why a 4-credit A moves your GPA more than a 1-credit A. The math updates live as you type.
What's the difference between weighted and unweighted GPA?
Weighted GPA gives a bump for harder courses — commonly +0.5 for Honors and +1.0 for AP/IB, so an A in AP Calculus counts as 5.0. Flip the Weighted switch and a level selector appears for each course. Note that schools vary in their exact policy, and colleges usually recalculate applicants on the unweighted 4.0 scale — the tool shows unweighted by default for that reason.
Can it calculate my cumulative GPA?
Yes. Enter your prior GPA and the credits it covers, and the tool combines them with this semester's numbers using the same formula your registrar uses: (prior GPA × prior credits + new grade points) ÷ total credits.
How does "what do I need on my final" work?
If your current grade is C, the final is worth w% of the course, and you want to finish at T, the required score is (T − C × (1 − w)) ÷ w. The tool gives you a straight verdict: green if you've already secured the grade even with a zero, and an honest "not mathematically possible" if even a perfect 100 falls short. Get the final's weight from your syllabus.
Are my grades saved or uploaded anywhere?
Never uploaded — the entire calculator runs in your browser, and your grades are nobody's business but yours. Your entries auto-save to this browser's local storage so they're still here when you come back, and the Reset button clears them.
Is this tool free?
Yes — completely free, with no sign-up needed.

Gradient Descent Visualizer

https://thedollarweb.com/tools/gradient-descent-visualizer.html Free
+
What is the Gradient Descent Visualizer?
An interactive demo of how nearly all machine learning models learn. The model is a ball, the error is a landscape, and training is the ball rolling downhill one step at a time. You control the landscape, the starting point (click anywhere on the curve), the learning rate, and momentum, then press Play or step through move by move while the training loss curve draws itself underneath.
What is a learning rate, in plain words?
The size of each downhill step. It is the single most important dial in training: too small and the ball crawls, needing hundreds of steps; too large and each step overshoots the bottom, so the ball zigzags higher until it flies off the chart. That blow-up is called divergence, and cranking the slider lets you watch it happen safely.
What is a local minimum?
A dip that is lower than everything around it but not the lowest point overall. On the two-valleys landscape, start the ball on the right with no momentum: it settles in the nearest valley and stops, because every direction out is uphill. The status honestly tells you a deeper valley exists. This is why training the same model twice can give different results.
What does momentum do?
It lets the ball keep part of its speed from previous steps, like a heavy ball rolling instead of a light one being nudged. With momentum around 0.9, the ball can coast through the shallow dip and reach the deeper valley next door. Some version of momentum is inside nearly every modern optimizer.
What's the chart at the bottom?
Loss over steps: the training curve, the exact chart ML engineers watch all day. A healthy run falls fast and flattens. A diverging run bends upward and leaves the chart. A stalled run goes flat while the loss is still high, which the plateau landscape produces on demand.
Is this how real neural networks train?
Yes, in spirit and in algorithm. A real network has millions of dials instead of one, so its landscape is a surface nobody can draw, but the procedure walking it is this one, and the failure modes you see here (oscillation, plateaus, local dips) show up at every scale. When someone says "the loss blew up," you have now watched exactly what they mean.
Is this tool free?
Yes, free with no sign-up, and it works offline once loaded. It pairs with the ML Overfitting Simulator and ML Performance Metrics on this site as a three-part introduction to how models learn, fail, and get measured.

Hash Generator

https://thedollarweb.com/tools/hash-generator.html Free
+
What does the Hash Generator do?
The tool creates MD5 and SHA-256 hashes for both text input and file contents. It can process single strings, multiple lines, or entire text/CSV files.
How do I use it?
Type text directly into the input box or upload a .txt or .csv file. Each line is treated as a separate input string, and empty lines can be skipped automatically.
What algorithms are supported?
You can choose between SHA-256 (recommended for integrity and security) and MD5 (fast but insecure, suitable only for simple checksums).
Can I clean up my input?
Yes. Options include trimming whitespace, skipping empty lines, and deduplicating inputs before generating hashes.
How do I export results?
You can copy hashes to your clipboard, export them as CSV, or download a CSV file directly. The output includes the original input alongside the generated hash.
Is this tool free?
Yes, the Hash Generator is completely free to use with no subscription required.

Health Unit Converter

https://thedollarweb.com/tools/health-unit-converter.html Free
+
What does the Health Unit Converter do?
It converts common health and medical units between US and international systems: blood sugar (mg/dL ↔ mmol/L), HbA1c (% ↔ mmol/mol, with estimated average glucose), cholesterol, body weight, height, and body temperature. Type a value in any box and the others update instantly.
Why does cholesterol have a "lipid type" option?
Total, HDL, and LDL cholesterol convert between mg/dL and mmol/L with one factor (÷38.67), while triglycerides use a different one (÷88.57). Picking the correct type makes the mmol/L result accurate.
How does the HbA1c conversion work?
It converts between the DCCT percentage and the IFCC mmol/mol value, and also shows the estimated average glucose (eAG) those map to in both mg/dL and mmol/L. For example, 6.5% ≈ 48 mmol/mol ≈ an average glucose around 140 mg/dL.
Is my health information private?
Completely. Every conversion runs in your browser using built-in formulas — nothing you type is uploaded, logged, or stored anywhere.
Can I rely on this for medical decisions?
Use it to translate units, not to diagnose. Reference ranges vary by lab and individual, so always confirm important values with your lab report or a healthcare professional. It's free to use with no sign-up.

HEIC to JPG Converter

https://thedollarweb.com/tools/heic-converter.html Free
+
What does the HEIC to JPG Converter do?
It converts Apple's HEIC/HEIF photos (the default format on iPhones and iPads) into standard JPG, PNG, or WebP files that open anywhere — Windows, websites, email, and Android. It converts between JPG, PNG, and WebP too, and can batch-convert a whole camera roll at once.
Are my photos uploaded to a server?
No. Everything runs locally in your browser. The HEIC decoder and code download once from this site, get cached, and then all conversion happens on your device. Your photos never leave it — which matters because they're personal.
Can I convert many photos at once?
Yes. Drop or select as many files as you like, and download them individually or all together as a single ZIP. Change the output format, quality, or size and every image re-converts instantly, because the originals are decoded once and kept ready.
Does it remove location and camera data?
Yes. Converting re-encodes the image, which strips EXIF metadata — including GPS location — from every output file automatically.
Which output format should I choose?
JPG for the widest compatibility and sharing; WebP or AVIF for the smallest files at the same quality (AVIF appears only when your browser can encode it); PNG when you need lossless output or transparency. You can also set a maximum width or height to resize on the way out.
Is the HEIC to JPG Converter free?
Yes, it's completely free to use with no sign-up required.

Icon Library

https://thedollarweb.com/tools/icons.html Free
+
What does the Icon Library do?
The Icon Library provides access to a collection of downloadable icons. Each icon comes with a preview, short description, and a direct download link.
How do I find icons?
Use the built-in search bar to filter icons by filename or description. Results update dynamically as you type.
Is there pagination?
Yes. Icons are displayed in pages of 24 at a time, with navigation buttons to move forward or backward. Pagination adjusts automatically based on your search results.
What information is shown for each icon?
Each icon card displays a thumbnail image, a short description, and a download button. Hover effects highlight icons for better interactivity.
In what format are icons available?
Icons are stored as files in the /icons/ directory and can be downloaded directly in their native format (commonly PNG or SVG).
Is this tool free?
Yes, the Icon Library is completely free to use with no subscription required.

Image Compressor

https://thedollarweb.com/tools/image-compressor.html Free
+
What does the Image Compressor do?
The Image Compressor shrinks JPG, PNG, and WebP files so they load faster on the web or take less storage. You can drag in a single photo or a large batch, tune the quality, and download the results individually or as a single ZIP.
Which file formats are supported?
JPG, PNG, and WebP inputs are fully supported, and you can convert between any of those formats on output. You can also leave the output set to "Auto" to keep each file in its original format.
How does the quality slider work?
For JPG and WebP outputs, the quality slider controls how aggressively the encoder discards detail — higher values look better but create larger files. A value between 75 and 85 usually produces a file that looks identical to the original while cutting the size significantly. PNG output is lossless, so the slider doesn't apply.
Can I resize images at the same time?
Yes. Enter a maximum width, height, or both, and every image that exceeds those dimensions will be scaled down while preserving its aspect ratio. Smaller images pass through unchanged. Leave the fields blank to keep original dimensions.
Does it strip EXIF and other metadata?
Yes. Re-encoding through the browser canvas automatically removes EXIF data — including GPS coordinates, camera serial numbers, and editing history — which is helpful before publishing photos online. The "Strip EXIF / metadata" option is on by default.
Can I compare the before and after?
After compressing, each file has a compare button that opens a draggable before/after slider so you can inspect quality side by side. Each row also shows the old size, the new size, and the exact percentage saved.
What if the compressed file would be larger than the original?
With "Only save if smaller than original" checked, the tool keeps the original bytes when compression would actually grow the file — common for photos that are already heavily optimized. Uncheck the option if you want to force re-encoding anyway (for example, to change format or strip metadata).
Are my images uploaded anywhere?
No. The entire tool runs inside your browser using the HTML5 canvas and JSZip — your files never leave your device, which is ideal for private photos, client work, and confidential product images.
Is the Image Compressor free?
Yes, the Image Compressor is completely free to use with no subscription required.

Image Cropper

https://thedollarweb.com/tools/image-cropper.html Free
+
What does the Image Cropper do?
It crops any image in your browser with full control: pick a shape (rectangle, rounded, circle, oval, or pill), snap to a common aspect ratio, rotate or flip, add styled text, blur faces or other regions, apply filters, and export as PNG or JPG.
Can I crop a circle profile picture with a transparent background?
Yes — choose the circle shape, position it over the subject, and export a PNG. Everything outside the circle is true transparency, so it drops cleanly onto any background.
How do I save the crop to my phone's photo library?
On phones, tap "Save to Photos" — the share sheet opens with the cropped image attached, and choosing "Save Image" puts it straight into your camera roll. Computers get the classic download and clipboard copy.
Can I blur faces or license plates?
Yes. Add blur regions anywhere on the image (there's a face-detection assist), and they're baked into the export — useful before posting screenshots or street photos.
Is my photo uploaded anywhere?
No. Cropping and rendering happen entirely in your browser on your own device — the image never touches a server.
Is the Image Cropper free?
Yes, it's completely free to use with no sign-up required.

Image Resizer

https://thedollarweb.com/tools/image-resizer.html Free
+
What does the Image Resizer do?
It changes the dimensions of one image or a whole batch. Resize by percentage, set a maximum width/height to fit within, or pick an exact size (including ready-made social-media presets). Aspect ratio is preserved by default, so images aren't stretched unless you choose to.
Are my images uploaded anywhere?
No. Resizing happens entirely in your browser with the canvas API. Your images are never uploaded or stored — they stay on your device.
How do I resize to an exact size that's a different shape?
Choose "Exact size" and pick how to handle the mismatch: Crop (cover) fills the frame and trims the overflow, Pad (contain) fits the whole image and fills the gaps with a color or transparency, and Stretch forces the exact dimensions (which can distort). Social presets default to Crop so the image fills edge to edge.
Can I resize many images at once?
Yes. Drop or select as many as you like, apply your settings to all of them, and download them individually or together as a ZIP. You can also convert the format (JPG, PNG, WebP) while resizing.
Is the Image Resizer free?
Yes, it's completely free to use with no sign-up required.

Image Splitter for Instagram

https://thedollarweb.com/tools/image-splitter.html Free
+
What does the Image Splitter do?
It cuts one photo into 2-10 perfectly equal slides so that, posted as a single Instagram carousel, the picture continues seamlessly as people swipe — the "one wide image across many slides" effect. It also has a profile-grid mode that cuts a photo into a 3-wide mural of square tiles.
How do I keep the split from cutting through a face?
The preview draws dashed guides exactly where each seam will land. Drag the photo inside the frame (and zoom if needed) until faces and focal points sit safely inside a slide, then split.
What size are the exported tiles?
Exactly 1080×1350 pixels (4:5 portrait, Instagram's largest feed format) or 1080×1080 squares — your choice. Grid tiles are always square. If your photo doesn't have enough resolution for the slide count you picked, the tool warns you before export.
In what order do I post the tiles?
Carousel slides are numbered left to right — select them in order when creating the post. Grid tiles are trickier because Instagram shows your newest post first, so the files come numbered in the correct reversed upload order: just post upload-01, then 02, and the mural assembles correctly.
How do I get the slides into my phone's photo library?
Tap "Save all to Photos" — your phone's share sheet opens with every tile attached, and choosing "Save Images" puts them straight into your camera roll, ready to post. No downloading a file and moving it by hand. Each tile also has its own save button, and computers get a ZIP.
Is my photo uploaded anywhere?
No. The slicing happens on your device with the HTML5 canvas, and the tiles and ZIP are generated in your browser. There's no watermark on your slides.
Is the Image Splitter free?
Yes, it's completely free to use with no sign-up required.

Image to Black & White

https://thedollarweb.com/tools/image-to-black-and-white.html Free
+
What does the Image to Black & White tool do?
It converts a color photo into a black-and-white (or grayscale) version. You pick the conversion method, optionally adjust brightness and contrast, and download the result as PNG, JPG, or WebP.
How do I save the result to my phone's photo library?
On phones, tap "Save to Photos" after converting — the share sheet opens with the image attached, and choosing "Save Image" puts it straight into your camera roll. Computers get the classic download.
Why are there several conversion methods?
Different methods weight the red, green, and blue channels differently and give very different-looking results. There's no single "correct" black-and-white — a red apple and a green leaf can map to the same shade of gray under one formula and very different shades under another.
Which method should I pick?
For most photos, Luminosity (the default) is the right choice — it weights green heavily because the human eye is most sensitive to green light, producing the most natural-looking gray tones. Use Average or Lightness for a different aesthetic, single-channel modes for film-style effects, and Threshold to get pure black-and-white for line art or stencils.
What is the Threshold mode?
Threshold turns every pixel into either pure black or pure white based on a brightness cutoff. The result is high-contrast with no shades of gray — ideal for stencils, screen printing, logo cleanup, and a newspaper-style look.
Can I adjust brightness and contrast?
Yes. Both sliders run from -100 to +100 and are applied on top of whichever conversion method you choose. There's also an Invert toggle that swaps black and white (a film-negative effect).
What output formats are supported?
PNG (lossless, best for line art and logos), JPG (smaller file, best for photos), and WebP (modern format with great compression). JPG and WebP expose a quality slider so you can balance file size against visible artifacts.
Are my images uploaded anywhere?
No. The entire tool runs in your browser using the HTML5 canvas — your image never leaves your device.
Is this tool free?
Yes, the Image to Black & White tool is completely free to use with no subscription required.

Image to SVG

https://thedollarweb.com/tools/image-to-svg.html Free
+
What does the Image to SVG tool do?
It converts raster images — PNG, JPG, WebP, GIF, or BMP — into SVG (scalable vector graphics) files that can be resized to any dimension without losing quality. Everything happens in your browser, so your images are never uploaded anywhere.
What is the difference between "Vector Trace" and "Exact Copy"?
Vector Trace redraws your image using SVG paths and flat color regions — the result is a true vector you can scale, edit, and recolor, but it has a stylized look (fewer colors, smoother edges). Exact Copy embeds the original pixels inside an SVG wrapper so it looks identical to the source at any size, but the file is larger and isn't really "vector" in the editable sense.
Which mode should I pick for a logo or icon?
Use Vector Trace with the "Illustration" or "Line Art" preset. Logos and icons usually have a small number of flat colors, so tracing produces a small, clean SVG that scales perfectly. Line Art is best for black-and-white marks.
Which mode should I pick for a photograph?
If you need the SVG to look exactly like the photo, use Exact Copy — tracing a photo will never match pixel-for-pixel and can produce very large files. If you want a stylized, illustrator-style vector of the photo, use Vector Trace with the "Photo" preset and push the color count up in Advanced options.
What do the advanced sliders do?
"Colors" controls how many flat color regions are allowed — more colors = closer to the original, but many more paths. "Detail level" controls how aggressively small paths are omitted and how finely curves are fit. "Smoothing" blurs the input before tracing, which is useful for noisy photos. "Max dimension" rescales the image before tracing: lowering it makes the tool much faster and produces smaller SVGs.
Why is my traced SVG larger than the original image?
Photos and screenshots contain thousands of subtly different colors, so the tracer has to generate a lot of paths to approximate them. Reducing the color count, lowering the detail level, or switching to the "Illustration" preset will usually shrink the file significantly. For photos that need to stay visually identical, Exact Copy is often smaller than a high-detail trace.
How large a file can I convert?
The tool accepts images up to 20 MB. For best performance, tracing large images (above ~3 megapixels) can take 10-30 seconds — consider using the "Max dimension" slider in Advanced options to downscale first. Exact Copy is fast regardless of size.
Are my images uploaded?
No. The tracer runs entirely in your browser using ImageTracer.js, and Exact Copy simply re-packages your image data inside an SVG locally. Your file never leaves your device.
Is Image to SVG free?
Yes, it's completely free to use with no sign-up required.

Image to Text (OCR)

https://thedollarweb.com/tools/image-to-text.html Free
+
What does the Image to Text converter do?
It runs OCR (optical character recognition) on photos, scans, and screenshots and gives you back the text as editable, copyable content. Drop in one or more images — or paste a screenshot straight from your clipboard with Ctrl+V — click Extract text, then copy the result or download everything as a .txt file.
Are my images uploaded to a server?
No. The OCR engine (Tesseract, compiled to WebAssembly) runs entirely inside your browser. That matters here more than almost anywhere: receipts, IDs, medical letters, whiteboards, and chat screenshots are exactly the images people least want on a stranger's server. The first run downloads the engine and language model (a few MB, cached); your images themselves never leave your device.
How do I extract text from a screenshot fastest?
Take the screenshot, open the tool, and press Ctrl+V (Cmd+V on a Mac) — the image is added instantly from your clipboard. Click Extract text, then Copy. No file saving required at any point.
Which languages does it recognize?
17 languages: English, Spanish, French, German, Italian, Portuguese, Dutch, Russian, Polish, Turkish, Swedish, Arabic, Hindi, Chinese (Simplified and Traditional), Japanese, and Korean. Pick the language before extracting — it tells the engine which alphabet to expect.
Does it read handwriting?
Printed text works far better. Neat, well-spaced handwriting sometimes reads acceptably; cursive rarely does — that's an honest limitation of OCR technology in general, not just this tool. Every result comes with a confidence score so you know how much to trust it, and the text box is editable so you can fix misreads before copying.
How accurate is it, and how can I improve results?
On clean, printed text it's typically excellent. For photos: shoot square-on, in good light, without shadows, and prefer a sharp photo of the whole page over a blurry close-up. The tool automatically upscales small images before recognition, which noticeably helps screenshots. Low-confidence results are flagged so you can double-check them.
Can it handle multiple images or a scanned PDF?
Multiple images, yes — drop in a whole batch and each gets its own text box, plus a combined .txt download labeled by filename. For scanned PDFs, use the dedicated PDF OCR tool instead, which processes every page and can rebuild a searchable PDF.

Audio Overlay on Video

https://thedollarweb.com/tools/audio-overlay.html Free
+
What does the Audio Overlay tool do?
It lets you drop a music track, voiceover, or sound effect onto any video and line it up precisely. You see the video's thumbnail strip and the audio's waveform side by side on one timeline, drag the audio clip to the moment you want, preview, and export a new video file.
What video and audio formats are supported?
Any video your browser can play (MP4, WebM, MOV in Chromium) and any audio the Web Audio API can decode (MP3, WAV, M4A, OGG, FLAC in most browsers). The output is a WebM video with mixed audio.
How do I line up the audio precisely?
Drag the audio clip left or right along the timeline, or type an exact start time in seconds. A "skip into audio" field lets you trim dead space from the start of the audio track. The waveform and video thumbnails share the same time axis so visual sync cues are obvious.
Can I keep the video's original audio?
Yes. By default both tracks are mixed — adjust each track's volume independently with the sliders. Tick "Mute original video audio" if you want to replace it completely (for dubs, voiceovers, or music-video edits).
What if my audio is shorter than the video?
Enable "Loop audio" to keep it repeating until the video ends, or leave it off to let it play once and stop. What you hear in preview is exactly what the export will contain.
Why is the output a WebM file?
WebM (VP9 or VP8 with Opus audio) is the only video format browsers can encode directly, and it plays natively on YouTube, Chrome, Firefox, Edge, and modern social platforms. For MP4, convert the WebM afterwards with a tool like Handbrake or FFmpeg.
Are my video and audio files uploaded anywhere?
No. Decoding, mixing, preview, and export all happen locally in your browser using the Web Audio API and MediaRecorder. Nothing ever leaves your device.
Is the Audio Overlay tool free?
Yes, it's completely free to use with no sign-up required.

Age Calculator

https://thedollarweb.com/tools/age-calculator.html Free
+
What does the Age Calculator do?
Enter a date of birth and it shows the exact age in years, months, and days, plus running totals in months, weeks, days, hours, minutes, and live-ticking seconds. You also get a countdown to the next birthday, the day of the week you were born, your star sign and Chinese zodiac, your half-birthday, and the date of your next 1,000-day milestone.
Can I calculate age on a date other than today?
Yes — change the "Age as of" date to answer questions like "how old was I on my wedding day?" or "how old will my child be at the school enrollment cutoff?" It works for both past and future dates.
How is exact age calculated?
Using the standard civil convention: full years to the most recent birthday, then full months, then leftover days — with real calendar month lengths and leap years, not 30-day approximations. Leap-day birthdays are counted on February 29 when it exists and roll to March 1 in common years.
Why would I enter a time of birth?
It's optional, but it makes the hour, minute, and second totals precise — useful for down-to-the-minute milestones or settling which twin is older and by exactly how much.
Is my birth date private?
Yes. A birth date is a key piece of personal identity, so the calculation happens entirely in your browser — nothing is uploaded or stored on a server. The page can remember your inputs locally on your own device so results are instant next visit, and that's the only place they live.
Is it free?
Completely free, with no sign-up.

AI Document Chat

https://thedollarweb.com/tools/ai-document-chat.html Free
+
What does AI Document Chat do?
It's a private, ChatGPT-style assistant for your own files. Load PDFs, Word documents, or text files and ask questions in plain English — "What's the termination clause?", "Summarize the findings", "List the key dates". The AI finds the relevant passages, answers your question, and cites the exact excerpts it used so you can verify everything.
Are my documents or questions uploaded anywhere?
No — and unlike most "chat with PDF" services, not even to an AI provider. The language model itself downloads once into your browser's cache and runs right on your own device — on the graphics chip via WebGPU, or on the CPU if your browser doesn't support it. Your documents are read locally, indexed locally, kept only in memory, and forgotten when you close the tab. There is no server-side AI, no account, and nothing to breach.
Does it really work offline?
Yes. The first visit downloads the AI model (0.4–2.1 GB depending on which you pick) and the small search model; both are cached permanently by your browser. After that you can load the page, add documents, and chat with no internet connection at all — turn off your Wi-Fi and try it.
What do I need to run it?
Almost any current browser. With WebGPU (current Chrome, Edge, Firefox, or Safari) models run on your graphics chip — start with the Balanced model; switch to Fast on older machines or Best on a gaming-class GPU. Without WebGPU the tool automatically switches to a compact model that runs on your CPU: slower, but everything still works and stays private.
Which file types are supported?
PDF, Word (.docx), plain text, Markdown, CSV, JSON, and HTML — up to 50 MB each, several documents at once. Scanned PDFs contain pictures rather than text, so run those through our PDF OCR tool first and load the result here.
How accurate are the answers?
Small on-device models are very good at finding, extracting, and summarizing what's in your documents, though a large cloud AI is still stronger at deep general-knowledge reasoning — privacy is the trade. Every answer cites its source passages with page numbers; for anything important, click the citation and check the original wording.
Is AI Document Chat free?
Yes, it's completely free to use with no sign-up required.

AI Image Upscaler

https://thedollarweb.com/tools/image-upscaler.html Free
+
What does the AI Image Upscaler do?
It enlarges an image and reconstructs detail a plain resize would leave blurry. Drop a JPG, PNG, or WebP, choose 2×, 3×, or 4×, and a super-resolution neural network produces a larger, sharper version you can download as PNG or JPG. It works best on small thumbnails, low-resolution photos, screenshots, logos, and product shots.
How do I save the upscaled image to my phone's photo library?
On phones, tap "Save to Photos" — the share sheet opens with the upscaled image attached, and choosing "Save Image" puts it straight into your camera roll. Computers get the classic PNG/JPG downloads.
Does my image get uploaded to a server?
No. Everything runs locally in your browser. The AI model and WebAssembly runtime download once from this site, get cached, and then all processing happens on your device. Your image never leaves it.
What AI model does it use?
A sub-pixel convolutional super-resolution network (Shi et al., 2016) from the ONNX Model Zoo, run via ONNX Runtime Web (MIT-licensed, from Microsoft) compiled to WebAssembly. The network upscales image detail in overlapping tiles that are blended together seamlessly.
Will it add detail that wasn't in the photo?
Super-resolution reconstructs plausible edges and texture, but it cannot invent information that was never captured — it won't sharpen unreadable text into readable text or recover a face that wasn't there. Clean, mildly soft images upscale best; heavily compressed or noisy images carry their artifacts along.
How long does it take?
A small image is near-instant. Larger images are processed tile by tile on the CPU with a live progress count, so a few-megapixel photo can take several seconds. Very large inputs are processed at up to about 1100 pixels on the long edge internally, then fit to your chosen output size.
What formats can I download, and is transparency kept?
Download a lossless PNG or a smaller JPG. PNG transparency is preserved through the upscale; JPG flattens any transparent areas onto white.
Is the AI Image Upscaler free?
Yes, it's completely free to use with no sign-up required.

Image Watermarker

https://thedollarweb.com/tools/image-watermark.html Free
+
What does the Image Watermarker do?
This tool lets you add professional watermarks to your photos. Options include text watermarks, image-based watermarks (like a logo), and even website URLs turned into scannable QR codes.
How do I upload images?
Drag and drop photos directly into the app or click to browse. Once loaded, images are displayed on a canvas where watermarks can be applied.
What customization options are available?
Text: Adjust font, size, color, opacity, and rotation. Optionally repeat text across the whole image. Image: Upload a logo, adjust its size and transparency. URL/QR Code: Enter a website link to generate a QR code watermark with customizable size and opacity.
Can I control positioning?
Yes. Watermarks can be placed in nine preset positions (e.g., top left, center, bottom right) or added manually with clicks.
Are undo and clear options supported?
Absolutely. You can undo your last action, remove individual watermarks, or clear all watermarks from the image.
How do I save my work?
When ready, download the watermarked image with a custom filename as a PNG file.
Is this tool free?
Yes, the Image Watermarker is completely free to use with no subscription required.

Bulk Image Watermarker

https://thedollarweb.com/tools/image-watermark-bulk.html Free
+
What does the Bulk Image Watermarker do?
This tool applies watermarks to multiple images at once. Users can add both text-based watermarks and QR code watermarks to batches of images.
What file types are supported?
You can upload JPG, PNG, or WebP images. All processing happens locally in your browser, so no files are uploaded to external servers.
How do text watermarks work?
Add custom text with options to set font color, opacity, size (relative to image width), rotation, position (top-left, center, bottom-right, etc.), tiling across the image, spacing, and horizontal offset.
How do QR code watermarks work?
Enter a URL or text to generate a QR code. Customize size, opacity, position, edge margin, tiling, colors (foreground/background), and transparency.
Can I preview watermarks before applying them to all images?
Yes. The workspace lets you preview any selected image with the applied watermark settings before downloading.
How are images exported?
You can download watermarked images individually as PNG files or process all at once into a single ZIP archive.
Is this tool free to use?
Yes — batch watermarking with advanced customization and ZIP export is completely free to use.

Invoice Generator

https://thedollarweb.com/tools/invoice.html Free
+
What does the Invoice Generator do?
This tool creates professional invoices with customizable company details, customer details, service line items, and totals. It also supports company logos, invoice numbers, and custom footers.
How do I enter company and client details?
The interface includes separate tabs for company, customer, and invoice details. Users can add a company name, email, address, customer name, address, and email.
Can I add line items to the invoice?
Yes. You can add multiple service lines with descriptions and amounts. Totals are automatically calculated and displayed.
Does it support logos?
Yes. Users can upload a company logo, which is saved locally for reuse. Logos can be cleared or replaced at any time.
How are invoice numbers handled?
Invoice numbers are auto-generated based on the company name, date, and sequence number, ensuring unique and sequential identifiers.
Can I download the invoice?
Yes. Invoices can be exported as either PNG or PDF. The PDF includes a clickable link to The Dollar Web's homepage for easy access.
Is this tool free to use?
Yes — advanced invoice creation with professional formatting, logo support, and multi-format export is completely free to use.

Math Worksheet Generator

https://thedollarweb.com/tools/math-worksheet-generator.html Free
+
What does the Math Worksheet Generator do?
It creates unlimited printable math drill sheets with automatic answer keys. Pick addition, subtraction, multiplication, division, or any mix; set the number range and regrouping; then print or download a PDF. Every sheet has a name/date line and a score box, and the "New problems" button generates a fresh variation of the same skill in one click.
What does the regrouping setting control?
Whether problems require carrying (addition) or borrowing (subtraction). "Never" guarantees no problem needs it — verified digit by digit, so a no-regrouping sheet truly matches an early-year lesson. "Always" makes every problem require it, and "Mixed" allows both. Subtraction answers never go negative.
Can division problems have remainders?
Your choice. By default every division problem comes out even, because dividends are built from the divisor and quotient rather than picked at random. Tick "Allow remainders" and answers appear in the standard 7 R 2 format on the answer key.
What are the grade presets?
One-click setups for common levels: Grade 1 (add and subtract within 20, no regrouping), Grade 2 (within 100 with regrouping), Grade 3 (times tables to 12), and Grade 4 (multi-digit multiplication and division with remainders). They're starting points — adjust anything and the preset switches to Custom.
How do I keep the answer key off the student copies?
Uncheck "Include answer key page when printing" and only the worksheet prints. Leave it checked and the key prints as its own page after the worksheet — print once, keep the last page at your desk.
Are the worksheets really unique every time?
Yes. Problems are generated randomly within your settings and de-duplicated within each sheet, so two clicks of "New problems" give two genuinely different worksheets of the same difficulty. Handy for A/B test versions, re-dos, and siblings who compare homework.
Is it free and private?
Completely free — no watermarks, no accounts, no page limits. Worksheets are generated and turned into PDFs entirely in your browser; nothing you type is uploaded anywhere.

Mic & Webcam Test

https://thedollarweb.com/tools/mic-webcam-test.html Free
+
What does the Mic & Webcam Test do?
It's a complete pre-call gear check: a live microphone level meter and waveform with a clear "voice detected" verdict, a record-and-replay so you can hear how you actually sound, a camera preview showing your resolution and real frame rate, a snapshot download, and a left/right speaker test — all on one page.
Is my microphone or camera feed recorded or uploaded?
No. The audio and video go from your hardware to your screen and nowhere else — the meters and preview are computed locally by your browser. The optional 5-second replay clip is held only in your browser's memory and is discarded when you leave the page. Nothing ever touches a server.
Why does my browser ask for permission?
Browsers require your explicit consent before any page can access a microphone or camera — that's a good thing. The tool only requests access when you click a start button, and your browser shows an indicator the entire time the hardware is live. Clicking Stop (or closing the tab) releases it immediately.
The test works here, but people still can't hear me on my call. Why?
Then your hardware is fine and the problem is the meeting app's settings. Open its audio settings and select the same microphone that worked here — apps frequently default to the wrong device, especially after plugging in a headset.
What do "permission denied" or "device is busy" mean?
"Permission denied" means access is blocked — click the padlock/camera icon in the address bar, allow the permission, and reload (on macOS/Windows also check the system privacy settings). "Device is busy" means another program like Zoom, Teams, or OBS is holding the hardware — close it and try again. The tool shows these fixes automatically when it hits an error.
Can I test multiple microphones or cameras?
Yes — once a test is running, a device picker appears if you have more than one mic or camera, so you can switch between them and compare without touching your operating system settings.
Is it free?
Completely free, no sign-up, no install — it works in any modern browser on desktop and mobile.

ML Overfitting Simulator

https://thedollarweb.com/tools/ml-overfitting-simulator.html Free
+
What is the ML Overfitting Simulator?
An interactive playground for the most important failure mode in machine learning. A hidden "true pattern" generates noisy data, split into training and test sets; you control the model's complexity, how much training data it gets, the noise level, and regularization — and real models retrain instantly on every slider move, showing the fit, the training vs test error, and a verdict: underfitting, healthy, or overfitting.
What is overfitting, in plain words?
A model that memorized its homework instead of learning the subject. It threads perfectly through every training point — including the random noise — so its training score looks brilliant, but it falls apart on data it hasn't seen. The gap between training error and test error is overfitting made measurable.
How do I make overfitting happen?
Set training points to about 15 and drag complexity to 15. Watch the red curve wiggle through every dot while training error collapses toward zero and test error explodes. Then cure it two ways: drag data up to 200 (the wiggles get pulled back to the pattern), or raise regularization (training error gets worse and test error gets better — one of the deepest trades in the field).
What's the chart at the bottom?
The most reproduced figure in ML textbooks — training and test error across every complexity level — computed live from your data. Training error only ever falls as complexity grows; test error is U-shaped: it falls while the model genuinely learns, then climbs when it starts memorizing. The bottom of the U is the sweet spot, and the dot shows where your current model sits.
Is this how real machine learning works?
The models here are polynomial (ridge) regressions solved exactly — but the dynamics are universal. The same complexity-vs-data-vs-regularization triangle governs deep neural networks with billions of parameters, and it's why every serious model is evaluated on held-out test data. "It works on my training data" is the most dangerous sentence in ML.
What does the 🎲 resample button teach?
Variance, made visible. The true pattern stays fixed while the noise redraws — a degree-15 fit lurches dramatically with every resample (it's chasing noise) while a degree-4 fit barely moves. That instability is exactly what "high variance" means.
Does it need a server or GPU?
No — every model trains in milliseconds on your device, which is why the sliders feel instant. It works offline once loaded, and it's completely free. Great for teaching, courses, or finally building the intuition behind the buzzword.

ML Performance Metrics

https://thedollarweb.com/tools/ml-performance-metrics.html Free
+
What is the ML Performance Metrics explorer?
An interactive teacher for the numbers that ML results arrive in. Pick the kind of problem (classification, regression, or clustering), pick a metric, and a live simulation shows you what it measures while a plain-English card explains what it means, how to read it, and where it fools people. It's written for people who sit in meetings where these numbers decide things, not for people who build the models.
Which metrics does it cover?
Classification: the confusion matrix, accuracy, precision, recall, F1 score, and the ROC curve with AUC, all driven by a spam-filter simulation with a draggable decision threshold. Regression: MAE, RMSE, R², and MAPE on a simulated house-price model. Clustering: silhouette score and inertia with the elbow method on simulated customer groups.
What is the "accuracy trap" it demonstrates?
Set spam to 5% of email and push the threshold high: the filter catches almost nothing, yet accuracy stays above 90%, because calling everything "fine" is nearly always right when the bad outcome is rare. It's the single most common way people are misled by an ML number, and seeing it happen live teaches it better than any paragraph.
What's the difference between precision and recall, quickly?
Precision: when the model flags something, how often is it right? Recall: of all the real cases out there, how many did it catch? They pull against each other — drag the threshold slider and watch. Every production classifier sits somewhere on that trade, and a human chose where.
Why does it show both MAE and RMSE?
Because they answer different questions. MAE is the typical miss in real units; RMSE squares errors first, so rare huge misses count extra. The tool has an "add one huge miss" switch: flip it and watch RMSE jump while MAE barely moves. Now you know which number to ask for when rare disasters are what you fear.
Are the numbers real or just illustrations?
Real — every value is computed live from the simulated data on your device: actual confusion counts, a real threshold-swept ROC curve, real k-means runs with silhouette computed point by point. Move any slider and everything recomputes instantly.
Is this tool free?
Yes — free, no sign-up, works offline once loaded. Pair it with the ML Overfitting Simulator on this site for the other half of the ML-literacy picture.

Morse Code Translator

https://thedollarweb.com/tools/morse-code-translator.html Free
+
What does the Morse Code Translator do?
It converts plain text into Morse code and Morse code back into text as you type, and can play the code aloud as audio beeps with a flashing light.
How do I decode Morse back to text?
Paste or type the Morse into the lower box, using a single space between letters and a slash (/) between words — for example ... --- ... decodes to SOS. The text appears in the top box automatically.
Can I hear the Morse code?
Yes. Press Play to listen to the dots and dashes as tones, with a light that blinks in time. You can adjust the speed in words per minute, which is handy for learning or practicing.
Which characters are supported?
A–Z, the digits 0–9, and common punctuation. Characters without a standard Morse equivalent are skipped when encoding.
Is it free and private?
Yes. It's completely free with no sign-up, and everything — including the audio — is generated in your browser, so nothing you type is uploaded.

Mortgage Calculator

https://thedollarweb.com/tools/mortgage-calculator.html Free
+
What does the Mortgage Calculator do?
This tool helps users estimate their monthly mortgage payments by factoring in principal, interest, property taxes, home insurance, and PMI (Private Mortgage Insurance).
What inputs are required?
Users enter the home price, down payment, interest rate, loan term (in years), annual property tax, annual home insurance, and optional monthly PMI.
Does the tool account for PMI?
Yes. PMI is automatically set to $0 if the down payment is 20% or more of the home price, unless manually overridden. A warning message appears if PMI applies.
How is the monthly payment displayed?
The results section shows a breakdown of principal & interest, property tax, home insurance, PMI, and the total monthly payment.
Is the calculator interactive?
Yes. Payments update in real time as values are entered or adjusted, and the "Calculate Payment" button triggers a full recalculation.
Is this tool free?
Yes, the Mortgage Calculator is completely free to use with no subscription required.

Movie & TV Watchlist

https://thedollarweb.com/tools/watchlist.html Free
+
What does the Movie & TV Watchlist do?
It's a private watch list that lives in your browser. Add movies and TV shows you want to watch, click ✓ Watched when you've seen one (the date is stamped automatically), rate it out of five stars, and keep notes like where it's streaming or who recommended it. Search, filter by movies vs. TV, and sort by date, title, or rating.
Do I need an account?
No. Unlike movie-tracking apps and websites, there's no sign-up, no profile, and no recommendation engine studying your viewing habits. Your list is stored in your own browser and never uploaded anywhere.
Where is my list saved, and will it still be here tomorrow?
The list is saved automatically to your browser's local storage on this device — it persists across visits, so it'll be here next week. Because it's device-local, your phone and laptop keep separate lists; use the Backup (JSON) and Import backup buttons to carry your list across devices. Clearing your browser data clears the list, so export a backup now and then.
Can I move something back from Watched to my watchlist?
Yes — every watched title has a "Watch again" button that moves it back to the watchlist (great for rewatches or shows with a new season). Deletes are protected too: an Undo button appears for a few seconds after you remove anything.
Can I export my list?
Yes, two ways: a CSV file with title, type, genre, status, dates, rating, and notes (opens straight in Excel or Google Sheets), or a JSON backup you can re-import on another browser. Importing merges — titles you already have are skipped, never duplicated or overwritten.
Why doesn't it look up posters and details from a movie database?
By design. Fetching details from a movie database would send what you're watching to a third-party server. This tool keeps entry manual and instant — type the title and hit Add — so your viewing list stays completely private.
Is this tool free?
Yes — completely free, with no limits on how many titles you can track.

What does the Name Selector do?
The tool allows you to input a list of names and spin a colorful digital wheel to randomly select a winner.
How can I add names?
You can add names one by one, paste a bulk list (comma-separated or one per line), or load a built-in example list. Names are displayed as removable chips for easy management.
What additional list features are available?
Options include shuffling the list, removing duplicates, exporting the list as a text file, and clearing all names at once. The list also autosaves in your browser for reuse later.
How does the wheel work?
Once names are added, you can spin the wheel in either normal or quick mode. The pointer at the top indicates the winner, and a banner with confetti celebrates the result.
Is the tool interactive and visual?
Yes. The wheel uses dynamic colors, labels, and animations to make the selection process engaging and visually fun.
Is this tool free?
Yes, the Name Selector is completely free to use with no subscription required.

Online Notepad

https://thedollarweb.com/tools/online-notepad.html Free
+
What does the Online Notepad do?
It's a blank page that opens instantly and saves everything you type automatically. You can keep multiple named notes, switch between them, see live word and character counts, and come back later to find your notes exactly where you left them.
Where are my notes stored?
Only in your own browser, on your own device, using local storage. Nothing is sent to a server, so your notes stay completely private. Because they live in this browser, clearing your browser data will remove them — download anything important.
Do I need to click save?
No. Every keystroke autosaves, and a "Saved" indicator confirms it. You can also press Ctrl/Cmd + S any time to force an immediate save.
Is there a dark mode?
Yes — toggle a dark editor, turn word wrap on or off, or switch to a monospace font for code and lists. You can also copy, download as a .txt file, or print any note.
Is it free?
Yes, completely free with no sign-up, and it works offline once the page has loaded.

Online Timer & Stopwatch

https://thedollarweb.com/tools/timer-stopwatch.html Free
+
What does the Online Timer & Stopwatch do?
It's two tools in one: a countdown timer that rings an alarm when it reaches zero, and a stopwatch with lap times. Use the timer for cooking, workouts, study sessions, or games, and the stopwatch to time anything precisely.
How do I set the timer?
Tap a preset (1, 3, 5, 10, 15, 20, 30, 45, or 60 minutes) or type any custom hours, minutes, and seconds, then press Start. You can add a label so you remember what the timer is for, and pause or reset it any time.
Does it make a sound when the timer ends?
Yes. When the countdown reaches zero, an alarm tone plays and the display flashes "Time's up!" with a button to stop it. The tone is generated in your browser, so there's no audio file to download.
Will it stay accurate if I switch tabs?
Yes. Timing is based on the real clock rather than a tick counter, so it stays accurate even when the tab is in the background — and the browser tab's title shows the remaining time so you can keep an eye on it from elsewhere. Keep the tab open while the timer runs.
Does the stopwatch record laps?
Yes. While the stopwatch runs, press Lap to record a split — the tool lists each lap time alongside the total elapsed time, with hundredths-of-a-second precision.
Is the Online Timer & Stopwatch free?
Yes, it's completely free with no sign-up, no ads, and nothing tracked. It even works offline once the page has loaded.

Party Invite Creator

https://thedollarweb.com/tools/party-invite-creator.html Free
+
What does the Party Invite Creator do?
It's a full-featured canvas-based invitation designer. You pick a canvas size, choose from 12 professionally designed templates (or build your own background), then add, style, and position text, stickers, and photos on a layered canvas. When you're done, export as a high-resolution PNG, JPG, or print-ready PDF, copy to clipboard, or share via the native share sheet on mobile.
What canvas sizes are available?
Eight presets cover the most common invitation use cases: 5×7 portrait (classic card), 7×5 landscape, 1:1 square (Instagram post), 9:16 story (Instagram/TikTok), 4×6 portrait/landscape, US Letter, and A4. Print sizes export at 300 DPI so they're ready for a professional printer.
What templates are included?
12 curated templates with coordinated gradients and patterns: Confetti, Balloons, Elegant, Birthday, Summer, Minimal, Neon, Pastel, Retro, Winter, Garden, and Midnight. Every template has a real, rendered pattern (confetti, balloons, dots, waves, stars, snowflakes, zigzags, grid, chevron, triangles, and more) that scales cleanly at any size.
Can I use my own photo as the background?
Yes. Upload any photo to use as a background and fine-tune it with a tintable color overlay (adjustable opacity) and an optional blur to push it behind your text. You can also switch between the template background, a solid color, a two-color gradient with adjustable angle, or the photo at any time.
How do text and sticker layers work?
Everything on the canvas is a layer. Add as many text, sticker, or image layers as you want, then drag to reposition, use the properties panel for precise values, rotate any layer, or reorder the stack with the layers panel. Click any layer to select it; the toolbar exposes fonts, size, bold/italic, alignment, color, shadow, and outline — plus quick emoji stickers.
Can I undo mistakes?
Yes. The editor keeps a 60-step undo history. Use the Undo/Redo buttons or keyboard shortcuts Ctrl/Cmd+Z and Ctrl/Cmd+Y (or Ctrl/Cmd+Shift+Z). Duplicate selected layers with Ctrl/Cmd+D, delete with Delete/Backspace, and nudge with arrow keys (hold Shift for 10× the step).
Will my work be saved if I refresh?
Yes. The editor autosaves your design to your browser's localStorage, so closing the tab or refreshing the page won't lose your progress. Your design never leaves your device.
How do I export or share the invite?
Five options: download as PNG (transparent-capable, high-res), JPG (smaller file for text messages and email), PDF (print-ready with exact physical dimensions), copy to clipboard (paste into docs, chats, or social media), or use the native Share sheet on iOS/Android to send directly to Messages, WhatsApp, email, and more.
Is my data private?
Completely. Every operation — rendering, export, autosave — happens locally in your browser. Your photos, text, and designs are never uploaded to a server.
Does it work on mobile?
Yes. The editor is fully responsive: the canvas scales to your viewport, touch drag works for repositioning layers, and mobile Safari/Chrome expose the native Share sheet so you can send the invite directly to Messages, Mail, WhatsApp, or any other app.

Photo Collage Maker

https://thedollarweb.com/tools/photo-collage.html Free
+
What does the Photo Collage Maker do?
It lets you drop a handful of photos into a chosen layout, fine-tune how each photo is framed, and export a single high-resolution image. You can adjust spacing, borders, corner rounding, and the background color, apply a filter to any photo, and pick a canvas size that matches Instagram, prints, or any custom dimensions you need.
How many layouts are there?
Seventeen — including a single photo, 2- and 3-photo strips (horizontal and vertical), 2x2 / 3x2 / 3x3 / 4x4 grids, and asymmetric mixes like "1 big + 2 small", "2 small + 1 big", "1 + 3 below", "3 above + 1", and "1 + 4 below". You can switch between layouts at any time and your photo assignments will be preserved as far as possible.
How do I add photos?
Click the "Add photos" zone and pick files, drag images directly onto it from your computer, or paste an image straight from your clipboard. Newly added photos automatically fill the next empty cells in the layout. After that, drag any thumbnail from the library onto a cell to swap it, or click a cell and then click a thumbnail to assign it.
Can I crop or reposition individual photos?
Yes. Click a cell to select it, then drag inside the cell to pan the photo, or scroll your mouse wheel to zoom from 1x up to 3x. The right-side panel also has rotate (0/90/180/270 degrees), horizontal/vertical flip, and a "Reset photo" button to return to the default crop.
What filters are available?
Each photo can use one of eight looks: None, Black & White, Sepia, Vivid, Fade, Cool, Warm, and High Contrast. Filters are applied per-photo so you can mix styles across the same collage.
What canvas sizes can I export?
Built-in presets cover Instagram Square (1080x1080), Instagram Portrait (1080x1350), Instagram Story (1080x1920), 16:9 Landscape (1920x1080), 3:2 and 4:3 photo prints, and Letter portrait/landscape at 300 dpi (2550x3300 / 3300x2550). There's also a Custom option where you can dial in any width and height between 200 and 6000 pixels.
Does my photo get uploaded to a server?
No. Loading, layout, editing, and export all happen entirely inside your browser using the HTML5 Canvas API. Your photos never leave your device.
What format does it export?
PNG (lossless, supports the background color you chose) or JPG (smaller file, ideal for sharing). Both export at the full resolution of the canvas size you picked, regardless of how the preview is displayed.
Is the Photo Collage Maker free?
Yes, it's completely free to use with no sign-up required.

JSON Formatter & Validator

https://thedollarweb.com/tools/json-formatter.html Free
+
What does the JSON Formatter & Validator do?
Paste any JSON and it instantly pretty-prints it with your choice of indentation, validates it against the JSON spec, and — if something's wrong — tells you the exact line and column with the offending line highlighted. You can also minify it, sort keys, and explore the data in an interactive collapsible tree.
Is my JSON uploaded anywhere?
No. Everything is parsed and formatted locally with your browser's built-in JSON engine. Your data is never uploaded or logged — which matters when a payload contains API keys, tokens, or customer data.
How does it help me find errors?
When JSON is invalid, you get a clear message plus the precise line and column of the problem, with that line shown and a caret pointing at it. The usual culprits — trailing commas, single quotes, and comments — are flagged because strict JSON doesn't allow them.
Can it handle large or deeply nested JSON?
Yes. The tree view lets you collapse sections and shows key counts and array lengths at each level, so you can navigate huge documents without endless scrolling. Size is limited only by your device's memory.
Is the JSON Formatter free?
Yes, it's completely free to use with no sign-up required.

Kanban Board Maker

https://thedollarweb.com/tools/kanban-board.html Free
+
What does the Kanban Board Maker do?
It's a visual task board: columns for each stage (like To Do, In Progress, Done) and cards you drag from one to the next as work moves along. You can keep multiple boards, add custom columns, and give cards a priority, due date, description, and color label.
How do I move a task between stages?
Just drag the card and drop it in another column — you can also reorder cards within a column, and rearrange whole columns by dragging their headers. Everything updates and saves instantly.
Are my boards saved? Where?
Yes — every change is saved automatically to your browser's local storage on your own device, so your boards are right where you left them next time you visit. Nothing is uploaded to a server. Because they live in this browser, clearing your browser data will remove them, so use Export to back up a board as a file.
Can I undo a change?
Yes. Use the Undo button or press Ctrl+Z (Cmd+Z on Mac) to step back through recent changes made in the current session.
Can I move a board to another computer?
Yes. Click Export to download the board as a JSON file, then open the tool on the other device and click Import. This is also the best way to keep a backup.
Is the Kanban Board Maker free?
Yes, it's completely free to use with no sign-up required, and there's no limit on the number of boards, columns, or cards.

Label Maker

https://thedollarweb.com/tools/label-maker.html Free
+
What does the Label Maker do?
It lets you design address, shipping, file folder, name tag, and product labels and download a print-ready PDF that lines up with standard Avery-compatible label sheets. Choose a sheet template, pick a design style, type your content (or upload a CSV for mail merge), then export.
Which label sheets are supported?
Fifteen common templates across US Letter and A4 paper, including Avery 5160 (1"x2 5/8" address, 30/sheet), 5161, 5162, 5163 (shipping), 5164 (large shipping), 5167 (return address), 5168, 5195 (file folder), 5294 (round, 2 1/2"), 5366 (file folder), and 5395 (name badge); plus L7160, L7163, L7165, and L7651 for A4. The PDF is sized exactly to the official Avery specs so it prints in registration with your sheet.
What design styles are available?
Twelve styles: Plain, Bordered, Rounded, Double Border, Dashed, Top Bar, Bottom Bar, Sidebar, Header, Frame, Corner Accents, and Gradient. Each style works on every sheet template, and you can customize the primary, background, and text colors plus typography (Helvetica, Times, or Courier; size 5–32pt; left/center/right alignment; bold title toggle).
Can I print different content on each label (mail merge)?
Yes. Choose "List" mode and paste one entry per line using Title|Line 1|Line 2|Line 3|Line 4, or choose "CSV" and upload a CSV file (first row treated as a header). Columns map to Title, Line 1, Line 2, Line 3, and Line 4 by position. The labels render in order and fill across rows.
Can I add a QR code to each label?
Yes. Toggle on "Include QR code", paste any URL or text, and pick a placement: left side, right side, top-right corner, or bottom-right corner. The QR size is configurable (30–90% of the label's height). For mail-merge runs, the same QR data is used on every label.
What if I already used some labels on a partial sheet?
Use the "Start at label" offset to skip the first N positions on the first page so the remaining labels print onto the empty cells of your partial sheet. Subsequent pages start at position 1 as usual.
How do I make sure my labels line up when printed?
Print the PDF at 100% scale (do not select "Fit to page" or "Shrink to fit") on the matching Avery sheet for that template. The cut marks option draws faint corner crops on each label so you can verify alignment with a test print on plain paper before committing a full label sheet.
Does my data get uploaded to a server?
No. Everything — design, mail merge, QR rendering, and PDF export — happens entirely in your browser using the local jsPDF and qrcode.js libraries. Nothing is sent anywhere.
Is the Label Maker free?
Yes, it's completely free to use with no sign-up required.

LLM Next-Word Playground

https://thedollarweb.com/tools/llm-next-word-playground.html Free
+
What is the LLM Next-Word Playground?
An interactive explainer for how ChatGPT-style models work. It trains a small word-prediction model on any text you give it (built-in samples included: Alice in Wonderland, the Gettysburg Address, nursery rhymes) and then shows you the model's honest odds for every next word as live probability bars. Click a bar to choose the word yourself, or press Auto-write and watch it generate.
Is this how ChatGPT actually works?
The core loop is identical: context in, a probability for every possible next word out, sample one, repeat. This toy counts word patterns directly while a real LLM learns deeper structure with billions of parameters, so the difference is scale and depth, not kind. The generation loop, the temperature dial, and the must-always-answer property are the real thing.
What does the temperature setting mean?
It reshapes the odds before the dice roll. Low temperature exaggerates the leading word, so output turns safe and repetitive (watch it fall into loops at 0.1). High temperature flattens the bars, so unlikely words get real chances and output turns creative, then incoherent. Drag the slider and watch the bars change shape live. Chat products typically run around 0.7 to 1.0.
What is a context window?
How many previous words the model considers when predicting the next one. Here it's 1 to 3 words; real models handle thousands, which is how they stay on topic across pages. Try 1 word (word soup) versus 3 (phrases hold together) and notice the catch: longer context needs more training text, because the model must have seen those exact word runs.
Does this explain why AI makes things up?
Yes, and seeing it is the point. The probability bars never contain "I don't know"; the model must always produce a next word, and its odds come from patterns rather than facts. When a pattern is strong but reality disagrees, it writes the wrong thing with perfect fluency. Watch this little model confidently invent nursery-rhyme lines that never existed, and you understand hallucination mechanically.
Can I train it on my own writing?
Yes — paste anything: emails, an essay, meeting notes. It builds the model instantly on your device (your text is never uploaded) and generates sentences that sound eerily like you. That familiarity is pattern matching rather than understanding, and feeling the difference firsthand is worth more than any explanation.
Is this tool free?
Yes — free, no sign-up, works offline once loaded. It's part of the ML literacy series on this site alongside the Gradient Descent Visualizer, the ML Overfitting Simulator, and ML Performance Metrics.

Loan & Amortization Calculator

https://thedollarweb.com/tools/loan-calculator.html Free
+
What does the Loan & Amortization Calculator do?
Enter a loan amount, interest rate, and term and it shows your regular payment, total interest, total paid, and payoff date, plus a full amortization schedule and a chart of the balance shrinking over time. It works for auto, personal, and student loans, and more.
What is an amortization schedule?
It's the payment-by-payment breakdown of a loan, showing how much of each payment goes to interest versus principal and the remaining balance after each one. You can view it by year or by individual payment, and download it as a CSV.
Can I see how much an extra payment saves?
Yes. Add an extra amount to each payment and the calculator shows how much interest you save and how much sooner the loan is paid off. You can also switch to bi-weekly or weekly payments, which often reduces total interest.
Does it include taxes, fees, or insurance?
No — it calculates principal and interest only. Real loans may add fees, insurance, taxes, or escrow that aren't included, so treat the results as planning estimates. For home loans with taxes and PMI, try the Mortgage Calculator.
Is it free and private?
Yes. It's completely free with no sign-up, and all the math runs in your browser — your loan details are never uploaded.

Lorem Ipsum Generator

https://thedollarweb.com/tools/lorem-ipsum-generator.html Free
+
What does the Lorem Ipsum Generator do?
It creates Lorem Ipsum placeholder text — the meaningless filler designers and developers use to mock up a layout before the real copy is ready. You choose how much you need and copy or download it instantly.
How much text can I generate, and in what units?
Generate by paragraphs, sentences, words, or list items, and set exactly how many of each. Click Generate again any time for a fresh block of the same size.
Can I get it with HTML tags?
Yes. Turn on "Wrap in HTML tags" to output <p> paragraphs or a <ul>/<li> list you can paste straight into your markup. You can also download it as a .txt or .html file.
Can I start with the classic "Lorem ipsum dolor sit amet" line?
Yes — that option is on by default so the output begins with the traditional opening. Turn it off if you'd prefer fully random filler text.
Is the Lorem Ipsum Generator free?
Yes, it's completely free with no sign-up. Everything is generated in your browser, so nothing is uploaded.

Flowchart Maker

https://thedollarweb.com/tools/flowchart.html Free
+
What does the Flowchart Maker do?
It's a browser-based diagram editor for flowcharts, process maps, and lightweight architecture diagrams. Drag shapes from the palette, connect them with arrows, edit labels, style fills and strokes, and export to PNG, JPG, SVG, PDF, or a re-openable JSON file.
What shapes are included?
Basic flowchart symbols (process, rounded box, decision, terminator, subprocess, note, connector dot, text), data shapes (document, multi-doc, data, database, manual input), architecture symbols (cloud, server, user, storage, queue), and advanced symbols (preparation, delay, OR, sum, off-page, card). Each shape can be resized by dragging its handles, and labels can be positioned at the top, center, or bottom.
How do I draw arrows between shapes?
Hover over a shape to reveal four anchor dots on its edges, then drag from any anchor onto another shape. You can also drag a connector style (right-angle, straight, or curved) from the palette to drop a detached arrow you can attach later. Connected arrows reroute automatically when you move or resize shapes.
Can I detach an arrow from a shape?
Yes. Select an arrow, grab one of the endpoint dots, and drag it into empty canvas — the endpoint becomes free-floating. Once both endpoints are detached, you can drag the arrow body freely, copy and paste it, or reattach by dropping an endpoint back on a shape.
Does it support copy and paste?
Ctrl+C and Ctrl+V copy and paste shapes and arrows on the canvas with a stepped offset so duplicates are clearly visible. Ctrl+Shift+C copies the entire diagram as a transparent PNG to your clipboard, ready to paste into PowerPoint, Google Slides, Word, or email.
What export formats are available?
PNG (transparent or with background), JPG, SVG, and PDF. The full diagram is auto-cropped to the content bounds before export. You can also save and reload the editable source as a .flow.json file.
Are there templates to start from?
Yes — preset templates for common patterns like a web API architecture (user → web app → API → auth service → database) so you can drop a starter diagram and edit instead of building from scratch.
Does my diagram get uploaded to a server?
No. Everything — drawing, layout, exports, and clipboard copy — runs entirely in your browser using local Fabric.js and jsPDF. Nothing is sent anywhere.
Is the Flowchart Maker free?
Yes, it's completely free to use with no sign-up required.

Peer to Peer File Sharing

https://thedollarweb.com/tools/file-share.html Free
+
What does the Peer to Peer File Sharing tool do?
It lets you send any file directly from your browser to someone else's browser. The sender picks a file, copies a one-time share link (or scans a QR code), and the receiver opens the link, accepts the offer, and downloads the file. The file streams between the two browsers in 16 KB chunks over a WebRTC data channel.
Does my file get uploaded to a server?
No. The file's contents stream peer-to-peer over WebRTC and never touch any server — not ours, not anyone else's. The only thing that goes through a server is a small handshake that helps the two browsers find each other.
Is this tool fully client-side like the rest of The Dollar Web?
Not quite — it's the one tool on the site that depends on an outside service. To open a direct browser-to-browser connection, both peers need to exchange a tiny bit of connection metadata. We use the public PeerJS signaling broker for that handshake. The broker only sees a short random session ID and connection details — it never sees the file you're sending.
Are there any limits on how big a file I can send?
There is no built-in size limit. We've tested transfers above 2 GB. The practical ceiling is your network speed, how long both browser tabs can stay open, and the receiver's available disk space.
Are there usage limits I should know about?
The signaling broker is a free, shared, public service with no uptime guarantee — it can rate-limit during heavy use or be temporarily unavailable. Some networks (strict corporate firewalls or symmetric NATs) may also block direct peer connections. If a transfer won't connect, try again on a different network or device.
How long does the share link last?
The link is valid only while the sender's tab is open. As soon as the sender closes the page, the random session ID is released and the link expires. There is no way to reuse an old link after the tab closes.
Can I send a file to multiple people?
The current flow is one-to-one — each transfer connects one sender and one receiver. If you need to send the same file to several people, after one transfer finishes you can click "Send another file" and share a fresh link with the next person.
Is this tool free to use?
Yes — Peer to Peer File Sharing with unlimited transfers, no file-size cap, and QR-code link sharing is completely free to use.

Passport & ID Photo Maker

https://thedollarweb.com/tools/passport-photo.html Free
+
What does the Passport & ID Photo Maker do?
It turns a normal head-and-shoulders photo into a print-ready passport, visa, or ID picture. An AI model replaces the background with passport-standard white or light blue, you pick your country and document size, line your face up with on-screen guides, and download a correctly sized photo plus a print sheet — all in your browser.
Is my photo uploaded anywhere?
No. Everything runs locally in your browser. The background model and runtime download once from this site, get cached, and then all processing happens on your device. Your photo never leaves it — which matters, because it's a picture of your face.
Which countries and sizes are supported?
Presets include US passport & visa and green-card/DV lottery (2×2 in), UK, Schengen/EU, Canada, India, Australia, China visa, Japan, a generic 35×45 mm ID, and a custom size in millimetres or inches. Everything is rendered at 300 DPI for printing.
Can I print several copies on one sheet?
Yes. The print-sheet option tiles as many compliant copies as fit on a 4×6 in, US Letter, or A4 page, with cut guides — ready for a drugstore print kiosk or your own printer at a fraction of a photo-booth price.
Will the photo be accepted by the government?
The on-screen guides help you size and position your head correctly, but they are aids, not an official compliance check. Requirements for head size, expression, attire, and background vary by country and document, so always confirm against the official specification before submitting.
Is the Passport & ID Photo Maker free?
Yes, it's completely free to use with no sign-up required.

Password Generator

https://thedollarweb.com/tools/password.html Free
+
What does the Password Generator do?
This tool creates strong, customizable passwords instantly in your browser. It offers options for uppercase letters, lowercase letters, numbers, and symbols, with adjustable length from 6 to 32 characters.
Can I customize password rules?
Yes. Advanced options let you exclude similar characters (like i, l, 1, o, 0), exclude ambiguous symbols, and enforce at least one character from each group.
Does it show password strength?
Absolutely. A real-time strength meter with categories (Weak, Fair, Good, Strong) updates as you adjust settings. The strength is based on character variety and length.
How do I use it?
Drag the slider to set length, check the boxes for character types you want, and click Generate Password. A password appears instantly, and you can copy it with one click.
Are my passwords safe?
Yes. All generation happens locally in your browser, and the tool explicitly notes that passwords never leave your device.
Is this tool free?
Yes, the Password Generator is completely free to use with no subscription required.

Percentage Calculator

https://thedollarweb.com/tools/percentage-calculator.html Free
+
What does the Percentage Calculator do?
It answers every common percentage question in one place: what is X% of Y, X is what percent of Y, the percent change between two numbers, and increasing or decreasing a value by a percent — plus quick tip and discount calculators. Every result updates live as you type.
Is anything I type sent anywhere?
No. All the math runs in your browser, so figures from a paystub, invoice, or private budget never leave your device.
Can it split a bill with tip?
Yes. The tip calculator takes the bill, tip percentage, and number of people, and shows the total with tip plus the amount each person owes.
How do I work out a sale price?
Use the discount calculator: enter the original price and the percentage off, and it shows both the final price and how much you save.
Is the Percentage Calculator free?
Yes, it's completely free to use with no sign-up required.

Pomodoro Timer

https://thedollarweb.com/tools/pomodoro-timer.html Free
+
What is the Pomodoro Technique?
Work with full attention for 25 minutes, take a real 5-minute break, and after four rounds take a longer 15-minute one. The timer enforces the rhythm so you don't have to. It's the simplest productivity system that survives contact with an actual workday — and starting a mere 25 minutes of work is easy enough to beat procrastination.
What does this Pomodoro timer include?
Focus/short-break/long-break phases with distinct chimes, cycle dots showing how far you are from the long break, auto-start options for breaks and focus sessions, a "what are you working on" label, daily stats (pomodoros completed and total focus minutes), and Space-bar start/pause. Session and break lengths are fully customizable — 50/10 deep-work blocks work just as well.
Does it keep time correctly if I switch tabs?
Yes — timing is based on the real clock rather than counting ticks, so background tabs, minimized windows, and busy CPUs never desync it. The countdown also shows in the browser tab title so you can see it while working in another tab.
Does it need an account or an app?
No. It runs entirely in your browser, works offline once the page has loaded, and the chimes are generated in the browser (no audio files). Your settings and today's stats are saved only in your own browser.
Why are breaks so important?
Because they're what makes the next session sharp — the technique is attention management, not endurance. Short breaks auto-start by default for exactly that reason: the system works when you actually take them. Stand up, look away from the screen, and come back when the chime calls you.
Can I change the 25/5/15 durations?
Yes — open Settings and set any focus length (1–120 min), break lengths, and how many sessions until the long break. Your preferences are remembered for next time. The exact numbers matter less than the rhythm: full attention, real rest, repeat.
Is this tool free?
Yes — completely free, no sign-up, and no ads interrupting your focus.

Pregnancy Due Date Calculator

https://thedollarweb.com/tools/due-date-calculator.html Free
+
How does the due date calculator work?
Enter the first day of your last menstrual period and your average cycle length. It uses Naegele's rule — about 280 days (40 weeks) from your last period — and adjusts for your cycle length to estimate your due date, then shows how far along you are, your trimester, your estimated conception date, and a timeline of milestones.
Why does it ask for my cycle length?
The standard 280-day calculation assumes a 28-day cycle with ovulation around day 14. If your cycle is longer or shorter, you likely ovulate later or earlier, so the tool shifts the estimate accordingly for a more personalized date.
Can I enter my due date directly?
Yes. Switch to the "I know my due date" option and type in the date from your provider or ultrasound. The calculator works backwards from it to show how many weeks pregnant you are, your trimester, and the milestone timeline.
How big is my baby this week?
Once you enter your dates, the calculator shows the classic comparison for your current week: baby is about the size of a familiar fruit or vegetable, from a poppy seed at week 4 to a watermelon at week 40, with the average length and weight alongside.
How accurate is the estimated due date?
It's an estimate, not a guarantee — only about 1 in 20 babies are born on their exact due date, and most arrive within two weeks either side. If your cycles are irregular or you're unsure of your last period, an early ultrasound gives a more precise date, and your provider's date always takes precedence.
Is my information private?

PDF Compressor

https://thedollarweb.com/tools/pdf-compressor.html Free
+
What does the PDF Compressor do?
This tool reduces the size of PDF files directly in your browser while keeping your files private. It offers presets for smallest, balanced, high quality, or maximum quality compression.
How do I upload a PDF?
Drag and drop your PDF into the upload area or click to browse. The file is processed locally—no server uploads are required.
What compression settings are available?
Smallest: 100 DPI, JPEG 0.55. Balanced (default): 150 DPI, JPEG 0.70. High Quality: 200 DPI, JPEG 0.80. Max Quality: 300 DPI, JPEG 0.90. Custom: Manually set DPI (72–600) and JPEG quality (0.40–0.95).
Does it show results?
Yes. After compression, the tool displays original size, new size, and total reduction (in MB and percentage). A progress bar and live status updates guide you through the process.
Can I cancel compression mid-process?
Yes. The tool includes a cancel button to stop compression while processing.
How do I download the compressed file?
Once finished, click the "Download Compressed PDF" button. The file will be saved with "-compressed" added to the original filename.
Is this tool free to use?
Yes — advanced in-browser compression with multiple quality settings is completely free to use.

PDF Form Filler

https://thedollarweb.com/tools/pdf-form-filler.html Free
+
What does the PDF Form Filler do?
If your PDF is an interactive form, it detects the fields — text boxes, checkboxes, radio buttons, and dropdowns — and lets you type straight into them on the page. If the PDF isn't fillable, you can switch on "Add text" and click anywhere to place your own text. Then flatten and download a finished PDF.
Is my document uploaded anywhere?
No. Pages are rendered and the PDF is built entirely in your browser. Your file is never uploaded, stored, or logged — important for the contracts, applications, and tax forms people fill out most.
My PDF has no fillable fields. Can I still use it?
Yes. Click "Add text," then click the spot on the page where you want to type. Adjust the size and color, and drag the handle to position it. This works on any PDF, including flat scans and exported documents.
What does "Flatten" do?
Flattening bakes your entries permanently into the page so the result looks identical in every viewer and can't be edited or accidentally cleared. Turn it off if you'd like the form fields to remain editable later.
Will it work on every PDF form?
Standard AcroForm PDFs work well. Some complex government forms use an older XFA technology that may not expose every field; in those cases the "Add text" tool is a reliable fallback. Editing a digitally signed PDF will invalidate its signature, which is expected for any change to a signed document.
Is the PDF Form Filler free?
Yes, it's completely free to use with no sign-up required.

PDF Hyperlink Editor

https://thedollarweb.com/tools/pdf-hyperlink-editor.html Free
+
What does the PDF Hyperlink Editor do?
This tool allows you to add clickable hyperlinks to existing PDF documents. You can create invisible link overlays, highlighted clickable areas, or text-based hyperlinks directly in your browser without uploading files to a server.
How do I add hyperlinks to a PDF?
Upload or drag and drop your PDF file into the editor. Once loaded, simply click and drag to draw a rectangle on any area of the page where you want to add a link. A dialog will appear where you can enter the URL and customize the link appearance.
What types of hyperlinks can I create?
You can create three types of hyperlinks: invisible overlays (no visible marking), highlighted areas (with customizable color and opacity), or text overlays (with custom text, color, size, and font). All types are fully clickable in the final PDF.
Can I make hyperlinks invisible?
Yes. Set the highlight color to transparent or adjust the opacity to 0, and leave the overlay text field empty. The link will be clickable but have no visible indicator in the final PDF. In the editor, invisible links are shown with a dashed border and eye icon for easy identification.
How do I customize hyperlink appearance?
When adding or editing a link, you can choose from preset colors or use a custom color picker for the highlight. Adjust opacity with a slider from 0 (invisible) to 100 (solid). For text overlays, customize the text content, color, font size, and font family (Helvetica, Times Roman, or Courier).
Can I add multiple hyperlinks to one PDF?
Absolutely. You can add unlimited hyperlinks across any number of pages in your PDF. The sidebar displays a list of all links with their URLs and page numbers. You can edit or delete any link by clicking on it in the editor or using the sidebar.
Does the tool work offline?
Yes. All PDF processing happens locally in your browser using PDF.js and pdf-lib libraries. After the initial page load, you can use the tool without an internet connection. Your files never leave your device.
Are my files uploaded to a server?
No. The tool operates entirely client-side in your browser. Your PDF files are processed locally on your device and are never uploaded to any server, ensuring complete privacy and security.
What happens when I save the PDF?
When you click "Save PDF," the tool creates a new PDF file with all your hyperlinks embedded as standard PDF link annotations. Any highlight colors or text overlays are drawn directly onto the PDF pages. The new file downloads with "-linked" appended to the original filename.
Can I edit or delete hyperlinks after adding them?
Yes. Click on any hyperlink overlay in the editor to open the edit dialog where you can modify the URL, colors, text, or other properties. To delete a link, click the × button that appears when hovering over it, or use the delete option in the edit dialog.
What browsers are supported?
The tool works in all modern browsers including Chrome, Firefox, Safari, and Edge. For best performance, use the latest version of your preferred browser with JavaScript enabled.
Is this tool free to use?
Yes — advanced PDF hyperlink editing with customizable overlays, text rendering, invisible links, and multi-page support is completely free to use.

PDF Multi-Search

https://thedollarweb.com/tools/pdf-multi-search.html Free
+
What does the PDF Multi-Search do?
This tool lets you upload multiple PDFs at once and search across all of them simultaneously. It finds every match, shows context snippets, and groups results by document — all processed locally in your browser.
How do I add files?
Drag and drop PDFs into the upload area or click "Select Files" to browse. Each file is indexed page-by-page so searches return results instantly.
What search options are supported?
You can toggle case sensitivity, whole-word matching, and full regular-expression (regex) patterns to fine-tune your search.

Yes. Results are grouped per document and per page, with a context snippet around each match and the matched term highlighted for easy scanning.
Can I export the results?
Yes — click "Export CSV" to download every match (document, page, matched text, surrounding context) as a CSV file you can open in Excel, Google Sheets, or any spreadsheet tool.
Are my PDFs uploaded to a server?
No. All indexing and searching happens entirely in your browser using PDF.js. Your documents never leave your device.
Is this tool free to use?
Yes — multi-document indexing, regex search, context highlighting, and CSV export are completely free to use.

PDF OCR

https://thedollarweb.com/tools/pdf-ocr.html Free
+
What does the PDF OCR tool do?
It takes a scanned PDF — where the pages are really just images — and extracts the text using OCR (optical character recognition). You get a page-by-page transcript you can search, copy, and export, plus an option to download a new "searchable PDF" that looks identical to the original but has an invisible text layer that any PDF reader can search and select.
What languages does it support?
17 languages out of the box: English, Spanish, French, German, Italian, Portuguese, Dutch, Russian, Polish, Turkish, Swedish, Arabic, Hindi, Simplified Chinese, Traditional Chinese, Japanese, and Korean. The first time you use a language, a small trained model (typically 3–15 MB) downloads from Tesseract's public CDN.
How accurate is the OCR?
Accuracy depends on the scan quality. Clean scans of printed text at 300 DPI usually exceed 95% word-level accuracy. Grainy, skewed, or low-contrast scans and handwritten text score lower. Every page shows a confidence badge (green ≥80%, yellow ≥60%, red below) so you can spot pages that may need review.
What's the "OCR quality" setting?
It controls the resolution at which pages are rendered before being fed to the OCR engine. Fast (150 DPI) is quickest but struggles with small text. Balanced (200 DPI) is a good default. High (300 DPI) gives the best accuracy on fine print but uses more CPU and memory per page.
Can I search the extracted text?
Yes. Once OCR finishes, use the search bar to find terms instantly across all pages. Toggle case sensitivity, whole-word matching, regex mode, or "Only show pages with matches" to narrow results. Matches are highlighted inline so you can jump straight to the relevant passage.
What's a searchable PDF, and how is it built?
A searchable PDF preserves the original scanned image exactly but adds an invisible text layer positioned over each word. Visually it looks identical to the original; functionally, text can be selected, copied, and searched in Adobe Reader, Preview, Chrome, or any other PDF viewer. The tool uses the word-level bounding boxes from OCR to place invisible text precisely over each detected word.
What export formats are supported?
Four: copy all text to clipboard, plain .txt (combined with page separators), structured .json (pages, words, bounding boxes, and confidence scores — useful for further processing), and searchable PDF (original pages + invisible text layer).
Is my PDF uploaded anywhere?
No. The PDF never leaves your device. Page rendering, OCR, search, and the searchable-PDF build all run locally in your browser. The only network requests are to load the OCR engine and language model from the Tesseract CDN the first time you use a given language.
How long does it take?
Roughly 2–8 seconds per page on a modern laptop at Balanced quality, plus a one-time language model download of a few seconds. A 20-page document typically finishes in under two minutes. Longer documents, higher DPI, and slower devices extend that linearly.

PDF Page Deleter

QR Code Reader

https://thedollarweb.com/tools/qr-reader.html Free
+
What does the QR Code Reader do?
It decodes a QR code and shows you what's inside before anything happens. Read codes from a screenshot, a photo, an image pasted with Ctrl+V, or your camera — links get a safety preview with the real domain highlighted, and Wi-Fi, contact, email, phone, SMS, and location codes are parsed into plain readable fields.
Why not just scan with my phone camera?
Phone cameras helpfully open whatever the code contains — which is the risk. Scammers put stickers over legitimate codes ("quishing") to redirect payments and logins. This reader shows the full URL and its real domain first, flags tricks like punycode lookalike domains, unencrypted links, and embedded credentials, and never opens anything until you choose to.
Can it read a QR code from a screenshot?
Yes — that's its specialty. Drop the screenshot in, or just press Ctrl+V to paste one. It even finds codes tucked into the corner of a larger page capture, and automatically retries small, inverted, or oversized images at different scales.
Is my image or camera feed uploaded?
No. Most online QR decoders upload your image to a server — think about what's in those screenshots: tickets, boarding passes, payment codes, Wi-Fi passwords. Here the decoding runs entirely in your browser with the open-source jsQR engine; images and the camera feed never leave your device.
What QR content types does it understand?
Website links, Wi-Fi network logins (with one-tap password copy), vCard and MECARD contact cards, email, phone, and SMS codes, geo-locations (with an optional map link), and plain text. Anything else shows as raw text with a copy button.
Is it free?
Completely free, no sign-up. QR Code is a registered trademark of DENSO WAVE Incorporated.

QR Customizer

https://thedollarweb.com/tools/qr.html Free
+
What does the QR Customizer do?

How do I add a logo to my QR code?
You can upload your own logo (PNG, JPG, or SVG up to 5MB) or choose from a searchable icon library. Logos can be resized (10–40% of QR width) and their opacity adjusted.
Does the tool support marketing analytics?
Yes, two ways. Built-in UTM tracking fields append campaign parameters (source, medium, campaign name, content) for your own analytics, with a live preview of the final URL. Premium members can also turn on scan tracking to count scans directly.
Can I see how many times my QR code was scanned?
Yes, with Premium. Turn on "Track scans" before generating and the code routes through a short thedollarweb.com link that counts each scan and instantly forwards to your destination. Click the analytics symbol on the saved code to see the total, a day-by-day timeline, and export a scans-per-day CSV. Each tracked code is unique to your account, and only scan timestamps are stored, nothing about who scanned.
What color and background options are available?
Choose any QR foreground color and optionally enable a transparent background (PNG only). JPG downloads are automatically set with a white background.
How do I download my QR code?
QR codes can be downloaded as high-resolution PNG (with or without transparency) or JPG. You can also set a custom filename before downloading.
Is there a default QR example?
Yes. The tool initially loads with a placeholder QR for "https://example.com." Users are prompted to generate their own before downloading.
Is this tool free to use?
Yes — advanced features like logo embedding, icon search, UTM tracking, and high-resolution exports are completely free to use.

How are QR codes displayed?
Each QR appears in a grid with a preview, the original text/URL, and a button to download it individually as PNG.
Can I download them all at once?
Yes. A Download ZIP option packages every QR code into a single archive, including a README file with generation details.
Does it support tracking?
Yes. The tool records when users generate batches, download singles, or export ZIPs, helping with analytics.
Is this tool free to use?
Yes — bulk generation, advanced error correction, ZIP exports, and analytics tracking are completely free to use.

Do generated QR codes work on all phones?
Yes. Most modern phone cameras recognize vCard QR codes and show an "Add to Contacts" option when scanned.
Is this tool free to use?
Yes — advanced contact sharing with multi-format exports and live previews is completely free to use.

Wedding Budget Calculator

https://thedollarweb.com/tools/wedding-budget-calculator.html Free
+
What does the Wedding Budget Calculator do?
Enter your total budget and guest count, and it splits the money across twelve categories using the percentages professional planners typically recommend — venue & catering around 40%, photography 12%, and so on, including the buffer everyone forgets. Every line is adjustable, you can add your own categories, and as you book vendors you record the real amounts to see over/under against the plan.
Are the recommended percentages rules?
No — they're the starting point planners use. Care more about photography than flowers? Move the points across; the dollar amounts recalculate instantly, and a banner tells you if your percentages drift from 100% with a one-click rebalance to fix it proportionally.
What's the "Booked" column for?
That's where budgets are actually won or lost. As you sign contracts, enter each real amount: the line shows how it compares to plan ("+$800 over" / "$1,200 left"), and the top cards track total booked and budget remaining. Going over on one vendor is fine — if you see it early and pull from another line.
Why does it show cost per guest?
Because guest count is the most powerful lever in wedding budgeting. Venue and catering — your biggest line — scale almost directly with headcount, so at typical rates, trimming ten guests frees more money than nearly any other single decision.
What's the buffer category?
About 9% held back for the surprises that hit every wedding: venue overtime, alteration costs, last-minute additions, delivery fees. Planners insist on it and couples skip it. Having it planned is what turns a surprise into a line item instead of a crisis.
Is my budget saved? Is it private?
It auto-saves to your own browser, so the plan is waiting as vendor quotes come in over the months — and it's never uploaded anywhere. The big wedding-planning sites run vendor-lead businesses on your data; here, your finances stay between the two of you.
Can I print it?
Yes — the Print button produces a clean budget sheet with your categories, percentages, planned and booked amounts, and totals. Perfect for the planning binder or a vendor meeting; choose "Save as PDF" in the print dialog for a digital copy.

White Noise Generator

https://thedollarweb.com/tools/white-noise-generator.html Free
+
What does the White Noise Generator do?
It plays steady masking sound for sleep and focus: white, pink, and brown noise plus fan and ocean flavors, with a volume slider, a tone control to darken the sound, a sleep timer with gentle fade-out, and a live visualizer. Press play, switch tabs, and it keeps going.
What's the difference between white, pink, and brown noise?
They're "colors" describing how energy is spread across frequencies. White is equal at every frequency — a bright, full hiss, strongest at masking high-pitched sounds. Pink falls off gently as pitch rises, matching how ears perceive loudness — softer and popular for focus. Brown concentrates energy in the lows — a deep waterfall-like rumble that's the internet's favorite for sleep and famously popular in ADHD communities.
Is it a recording? Does it loop?
No recording, no loop. The sound is synthesized live on your device with the Web Audio API — mathematically continuous noise with no seams, no buffering, and nothing downloaded. That's also why it works offline once the page has loaded.
How does the sleep timer work?
Pick 15, 30, 60, or 90 minutes and the sound fades out gently over the final ten seconds instead of cutting off abruptly. 90 minutes is roughly one full sleep cycle. And because there are no ads here, nothing will blare at you at 2 a.m.
Will it keep playing if I switch tabs or lock my phone?
In a background tab on a computer, yes. On phones, some browsers pause web audio when the screen locks — keeping the page open in the foreground or adding it to your home screen behaves best.
Does white noise actually help you sleep?
Honestly: the research is mixed at the population level, but masking works mechanically — steady sound hides sudden sounds, and sudden sounds are what wake you. If it works for you, that's the only trial that matters. Keep the volume moderate; masking works at surprisingly low levels, and all-night loud audio isn't kind to your ears.
Is this tool free?
Yes — free, no sign-up, no session limits, and your volume, tone, and noise choice are remembered in your browser for next time.

Wi-Fi QR Generator

https://thedollarweb.com/tools/qr-wifi.html Free
+
What does the Wi-Fi QR Generator do?
This tool creates QR codes that allow users to connect to Wi-Fi networks instantly without typing the password.
What details are required?
You need to enter the network name (SSID), choose the security type (WPA/WPA2/WPA3, WEP, or None), and, if applicable, provide the Wi-Fi password. You can also mark the network as hidden.
Can I customize the QR code?
Yes. Options include setting QR size (160–640px), adding a custom label under the code, and adjusting output format. The preview updates live as you type.
What formats are supported for saving?
PNG download (with custom filename), print-ready page with SSID details, and copy Wi-Fi payload (ZXing spec) directly to clipboard.
How does the payload format work?
Payloads follow the ZXing Wi-Fi specification: WIFI:T:<auth>;S:<ssid>;P:<password>;H:true;;
Does it work offline?
Yes. All QR generation happens locally in your browser—your Wi-Fi credentials are never uploaded.
Is this tool free to use?
Yes — secure offline generation with customizable options, print support, and live previews is completely free to use.

Quote Card Generator

https://thedollarweb.com/tools/quote-card-generator.html Free
+
What does the Quote Card Generator do?
It turns any quote you type into a polished, share-ready image. Pick a design template, choose a size for your platform, and download a PNG you can post directly to social media.
What design templates are included?
Twelve templates are built in, including Sunset, Ocean, Sage, Midnight, Forest, Lavender, Magazine, Typewriter, Neon, Coral, Mono, and a Dollar Web brand template — covering bold gradients, minimal layouts, vintage typography, and dark themes.
What sizes can I export?
Six presets are included: Instagram Square (1080×1080), Instagram Portrait (1080×1350), Instagram Story (1080×1920), Twitter/X (1600×900), LinkedIn (1200×627), and Facebook (1200×630).
Can I use my own quote and author?
Yes. The quote field accepts up to 280 characters, and the author field is optional. The text auto-fits the canvas as you type, so long quotes are scaled down to stay inside the frame.
What does the "Surprise me" button do?
It picks a random fact-checked quote from a curated list of 35 well-attributed quotes (Einstein, Maya Angelou, Steve Jobs, Lao Tzu, and more) and pairs it with a random template. It's a fast way to explore the look of different combinations.
Does my quote text leave my browser?
No. Everything is rendered locally on a canvas in your browser. Your text and the generated image never get uploaded to a server.
Is this tool free to use?
Yes — the Quote Card Generator with all 24 templates and 6 size presets is free to use, like every tool on The Dollar Web. No sign-up, no trial — at most a subtle thedollarweb.com credit in the card's corner.
How do I save the card to my phone's photo library?
On phones, tap "Save to Photos" — the share sheet opens with the card attached, and choosing "Save Image" puts it straight into your camera roll, ready to post. Computers get the classic PNG download.

Random Team Generator

https://thedollarweb.com/tools/team-generator.html Free
+
What does the Random Team Generator do?
Paste a list of names and it splits them into fair, randomized teams. You can divide the group by the number of teams you want or by how many people should be on each team, then copy or download the result.
How does it handle groups that don't divide evenly?
You choose. The tool can spread the extra people across teams so sizes differ by at most one, keep full teams and put the remainder in a smaller last team, or set the leftover people aside in their own group.
Are the teams really random?
Yes. Every run reshuffles the list with an unbiased Fisher–Yates shuffle, so there's no order bias from how you typed the names. Use "Shuffle again" for a fresh draw with the same settings.
Can I name the teams or reuse my list?
You can change the label from "Team" to anything you like, such as "Group", "Squad", or "Table". Your list and settings are saved in your browser between visits, and only in your browser.
Are the names uploaded anywhere?
No. Everything runs entirely in your browser, so the names you paste never leave your device — making it safe for student rosters, work lists, and guest lists alike.
Is the Random Team Generator free?
Yes, it's completely free to use with no sign-up required.

Read Time Calculator

https://thedollarweb.com/tools/read-time-calculator.html Free
+
What does the Read Time Calculator do?
Paste any text and it instantly estimates how long it takes to read — shown as a clear "X min read" plus exact minutes and seconds. It also gives a read-aloud time for scripts and speeches, along with live word, character, and sentence counts.
How is the reading time calculated?
It divides the word count by a words-per-minute reading speed. The default is 238 wpm — the average adult silent reading speed for English non-fiction. You can switch to Slow (150 wpm) for dense or technical material, Fast (350 wpm) for skimming, or drag the slider to any speed that fits your audience.
Can I get the time for reading aloud?
Yes. Alongside the silent reading time, the tool shows a read-aloud estimate at about 130 words per minute — a comfortable speaking pace — which is handy for presentations, speeches, and voiceover scripts.
Is my text uploaded anywhere?
No. Everything is calculated in your browser as you type — nothing is sent to a server, so unpublished drafts and confidential text stay private.
How accurate is the estimate?
It's based on well-established average reading speeds, so it's a reliable estimate rather than an exact stopwatch — actual time varies by reader and how dense the material is. Adjusting the words-per-minute slider lets you tailor it to your specific audience.
Is the Read Time Calculator free?
Yes, it's completely free to use with no sign-up required.

Reading List Tracker

https://thedollarweb.com/tools/reading-list-tracker.html Free
+
What does the Reading List Tracker do?
It keeps your three book piles straight: 📚 To read, 📖 Reading, and ✅ Finished. Add a title the moment someone recommends it, move it along with one click (dates stamp automatically), rate finished books out of five stars, and keep notes — who recommended it, that one quote. Search and sort by date, title, author, or rating.
Is this like Goodreads?
It's the tracking part without everything else: no account, no social feed, no recommendation algorithm, and no company learning your tastes. Your reading list is stored in your own browser and goes nowhere. Entry is deliberately manual — no book-database lookups means no third party ever knows what you're reading.
Will my list still be here next visit?
Yes — it auto-saves to your browser's local storage on this device and persists across visits. Because it's device-local, your phone and laptop keep separate lists; use Backup (JSON) and Import backup to carry it across. Clearing browser data clears the list, so take a backup once your shelf matters to you.
Can I track more than one book at a time?
Absolutely — the Reading shelf holds as many in-progress books as your nightstand does, no judgment. Books can also go straight from the to-read pile to Finished, back to the pile, or onto a re-read.
What stats does it show?
Counts for each shelf, books finished this year, and your average rating — right under the list. The "finished this year" number is quietly motivating by about March.
Can I export my books?
Two ways: a CSV (title, author, genre, shelf, dates, rating, notes — opens in Excel or Google Sheets) and a JSON backup you can import in another browser. Importing merges: books you already have are skipped, never duplicated or overwritten.
Is this tool free?
Yes — free, no sign-up, no limits on how many books you track. The Movie & TV Watchlist on this site works the same way for your screen time.

Regex Tester

https://thedollarweb.com/tools/regex-tester.html Free
+
What does the Regex Tester do?
You type a regular expression and instantly see what it matches — every match is highlighted in the test string, and a side-by-side panel breaks out each match's full text and every numbered and named capture group. There's a built-in sample paragraph full of emails, URLs, phones, prices, dates, IPs, and more to practice on.
Which languages does it generate code for?
JavaScript, Python, R, Java, C#/.NET, PHP, Ruby, Go, and grep (PCRE). Pick a language and it writes a copy-paste snippet that compiles your pattern with the correct flags and iterates the matches, handling raw strings, doubled backslashes, perl = TRUE in R, inline flags, and the (?P<name>) vs (?<name>) named-group difference for you.
Is matching done with each language's real engine?
Matching uses your browser's JavaScript regex engine. Most everyday patterns behave identically across languages, but engines differ on advanced features — lookbehind, recursion, possessive quantifiers, and POSIX classes aren't all portable. Go (RE2) omits backreferences and lookaround, and Ruby treats ^/$ as line anchors by default; the tool notes these per language.
Can I test a find-and-replace?
Yes. Enter a replacement using $1, $2, $& references and the tool previews the rewritten text live. You can also toggle global, ignore-case, multiline, dotall, unicode, and extended (verbose) flags.
Is the Regex Tester free?
Yes, it's completely free to use with no sign-up required, and your patterns and text never leave your device.

Remove Audio from Video

https://thedollarweb.com/tools/remove-audio-from-video.html Free
+
What does this tool do?
It strips the audio track out of a video file — completely and permanently — and gives you back a silent copy. Drop in a video, click "Remove audio," preview the result, and download it. The output is named yourvideo-no-audio.mp4 so your original is never overwritten.
Does removing the audio reduce my video's quality?
No — and this is the tool's biggest advantage. Instead of re-encoding your video (which is slow and degrades the picture), it performs a stream copy: the compressed video data is copied bit-for-bit into a new file, and the audio track is simply left out. The picture in the output is pixel-identical to your original.
Is my video uploaded to a server?
No. The tool runs FFmpeg compiled to WebAssembly inside your browser — your video is read locally, processed on your own device, and handed straight back. The first use downloads the processing engine (about 32 MB, cached for future visits); your video itself never touches the network.
Which video formats are supported?
MP4, MOV, M4V, WebM, MKV, AVI, and most other common formats. The output keeps the input's container family — MP4/MOV comes back as MP4, WebM as WebM, MKV as MKV. If a container refuses the copied stream, the tool automatically retries as MKV, which accepts virtually any video codec.
How long does it take? Is there a file size limit?
Seconds, in most cases — because nothing is re-encoded, even large files finish quickly once the engine is loaded. There's no imposed size limit; very large files are bounded only by your device's available memory.
Can someone "unmute" the downloaded video?
No. The audio track isn't muted — it's removed from the file entirely. There is no hidden sound data left to recover, which is exactly what you want before sharing a clip that had a private conversation in the background.
Can I replace the audio instead of just removing it?
Yes — strip the old soundtrack here first, then open the Audio Overlay on Video tool to add new music, a voiceover, or sound effects. And if you want to keep the audio as a file, the Audio Converter can extract a video's soundtrack to MP3, WAV, and more.

Resignation Letter Generator

https://thedollarweb.com/tools/resignation-letter-generator.html Free
+
What does the Resignation Letter Generator do?
It writes a graceful, professional resignation letter for you. Fill in your details, pick the situation — grateful standard, short and professional, new opportunity, retirement, or immediate — and click "Write my letter." The draft appears in a live business-letter preview where you can edit any word, then download a PDF, print it, or copy plain text.
What must a resignation letter include?
Three things: a clear statement that you're resigning, your position, and your last working day. Everything else is tone. A line of thanks and an offer to help the transition cost nothing and protect your references. What it must NOT include: complaints, criticism, or negotiating points — the letter goes in your permanent file; say hard things in person if they need saying.
How does the two-weeks-notice date work?
The "2 weeks out" button sets your last working day 14 days from today (there's a 4-week option for senior roles or long handovers), and the letter states the date explicitly — which is what HR actually needs. Check your contract: some roles require longer notice, and honoring it is part of leaving well.
Can I resign without notice?
The Immediate template covers genuine emergencies — and the tool shows an honest warning with it: resigning without notice can breach your contract or affect references, so check your employment agreement first. The letter itself is apologetic in tone, offers what transition help is reasonable, and skips the customary notice only because circumstances require it.
Is my letter private?
Completely — and it matters here more than almost anywhere: there's no browsing more sensitive at work than "resignation letter template." Everything, including the PDF generation, happens on your device. Your draft saves only to your own browser, so you can write it tonight and sleep on it before sending.
Should I email it or hand it over in person?
Best practice: tell your manager in person (or on a call) first, then hand over or email the letter as the formal record — the letter confirms the conversation rather than replacing it. Print it for the meeting or attach the PDF to a short, polite email afterward.
Is this tool free?
Yes — free, no sign-up, no watermark. The Cover Letter Generator and Resume Builder on this site cover the other end of the job change, just as privately.

Resume Builder

https://thedollarweb.com/tools/resume-builder.html Free
+
What does the Resume Builder do?
It turns a simple form into a polished resume. Choose from 12 professionally designed templates, fill in your details, and a live, page-accurate preview updates as you type. When you're done, export an ATS-friendly PDF — all in your browser.
Is my information uploaded anywhere?
No. Everything runs locally in your browser. Your resume autosaves only in your own browser's storage and to files you choose to download. Nothing is sent to a server — important, since a resume holds your name, contact details, and work history.
Are the resumes ATS-friendly?
Yes — use the Print button and choose "Save as PDF," which produces a file with real, selectable text that applicant tracking systems can parse. (The one-click "Download PDF" button saves a pixel-perfect image-based PDF instead, ideal for emailing or printing.) Single-column templates like Classic, Modern, and Minimal are the safest choices for strict ATS screening.
How do I download my resume as a PDF?
Click "Download PDF" and the finished file downloads immediately, matching the page size (A4 or Letter) you chose. If you need a version with selectable text for an ATS, use the "Print" button and pick "Save as PDF" with margins set to None.
How many templates and sections are there?
Twelve templates (Classic, Modern, Minimal, Executive, Compact, Elegant, Creative, Technical, Timeline, Corporate, and two Sidebar layouts) plus sections for summary, experience, education, skills, projects, certifications, languages, awards, and unlimited custom sections. You can rename, hide, delete, and drag to reorder every section and entry.
Can I save my progress and come back later?
Yes. Your work autosaves in your browser automatically. You can also export your resume as a JSON file to back it up or move it to another device, then load it back in any time.
Is the Resume Builder free?
Yes, it's completely free to use with no sign-up required.

Robots.txt Generator

https://thedollarweb.com/tools/robots-generator.html Free
+
What does the Robots.txt Generator do?
This tool builds valid robots.txt files directly in your browser. It includes quick presets, live preview, validation, and a path tester to check crawler access.
What presets are available?
Options include allow everything, block everything, allow only major search engines, block common AI/data crawlers, SEO baseline (blocks noisy system paths), and block sensitive directories (admin, login, checkout, etc.).
Can I customize rules?
Yes. You can add groups for specific user-agents with custom Allow, Disallow, Crawl-delay, and comments. Paths support wildcards and $ for end anchors.
Does it support sitemaps and host directives?
Absolutely. You can add multiple sitemap URLs and an optional host directive for crawlers that recognize it (like Yandex).
How do I test my configuration?
The built-in path tester lets you enter a user-agent and path. It highlights whether the path is ALLOWED or BLOCKED, and shows which rule applied.
How can I save or export?
Copy to clipboard, download as robots.txt, or save/load state locally with one click.
Is this tool free?
Yes, the Robots.txt Generator is completely free to use with no subscription required.

Scientific Calculator

https://thedollarweb.com/tools/scientific-calculator.html Free
+
What can the Scientific Calculator do?
It handles trigonometry (sin, cos, tan and their inverses), logarithms (ln and log), powers and roots, factorials, percentages, absolute value, and the constants π and e — building the whole expression on one line with parentheses.
Does it work in degrees or radians?
Both. Use the Deg/Rad button to switch; the current mode is shown on the display. Inverse trig functions return their answers in the same mode.
Can I use my keyboard?
Yes. Type digits and . + - * / ^ ( ) ! % directly, press Enter or = to evaluate, Backspace to delete, and Esc to clear. A live preview shows the result as you type.
Is there a memory function?
Yes — MC clears the memory, MR recalls it into your expression, and M+ / M− add or subtract the current value. An "M" indicator lights up when something is stored.
Is it accurate and private?
It uses a real expression parser that follows order of operations (not the browser's eval), and it runs entirely in your browser, so nothing you calculate is uploaded. It's free with no sign-up.

Screen Recorder

https://thedollarweb.com/tools/screen-recorder.html Free
+
What does the Screen Recorder do?
The tool records your screen with support for system audio, microphone input, or both. It offers high-quality captures up to 60 FPS and works directly in your browser.
How do I start recording?
Click Start Recording to capture your screen, a window, or a browser tab. You can choose whether to include system audio, microphone audio, or both before starting.
What happens after recording?
Once you stop, a preview appears immediately. You can then download the recording as an MP4 (recommended) or WebM file, or save the original WebM with no transcoding.
Does it support live preview?
Yes. After stopping a recording, you can play it back in the app before downloading.
Are there download options?
MP4: Converted with fast-start enabled for smooth seeking. WebM: Standard format with VP8/VP9 + Opus codecs. Original WebM: Highest fidelity, no transcoding.
Does it run locally or upload my recordings?
Everything runs in your browser. Your screen and audio are never uploaded to a server, keeping recordings private.
Is this tool free?
Yes, the Screen Recorder is completely free to use with no subscription required.

Screenshot Annotator

https://thedollarweb.com/tools/screenshot-annotator.html Free
+
What does the Screenshot Annotator do?
It marks up screenshots for sharing: arrows, boxes, ellipses, a highlighter, freehand pen, text labels, and numbered step badges — plus crop, and two redaction tools (pixelate and blackout) for hiding sensitive information. Paste an image with Ctrl+V, mark it up, then copy it back to your clipboard or download a PNG.
Is my screenshot uploaded anywhere?
No — and for this tool that matters more than most, because a screenshot you're redacting is sensitive by definition. Everything happens in your browser: the image goes from your clipboard to your screen, edits happen in memory, and nothing is sent to any server. Close the tab and it's gone.
Can the redaction be reversed?
No — the exported PNG is a flat image and the hidden region simply doesn't contain the original pixels. One honest nuance: a solid Blackout bar destroys the information completely, while heavy pixelation of known text has been partially reconstructed in research settings. For casual hiding, pixelate looks great; for an API key or account number, use Blackout.
Can I move or delete an annotation after drawing it?
Yes. Switch to the Select tool (or press V), click an annotation to grab it, drag it to move, or press Delete to remove it. There's full undo/redo with Ctrl+Z and Ctrl+Y, and clicking a color swatch recolors the selected annotation.
How do the numbered steps work?
Pick the step tool and click — each click drops a badge numbered 1, 2, 3, and so on. It's the fastest way to turn a settings screen into "click here, then here, then here" instructions.
How do I get the finished image out?
Two ways: "Copy" puts the annotated image on your clipboard so you can paste it straight into Slack, an email, or a ticket; "Download PNG" saves a file. Both are rendered at the screenshot's full original resolution.
Is it free?
Completely free — no sign-up and no watermark.

Screenshot Beautifier

https://thedollarweb.com/tools/screenshot-beautifier.html Free
+
What does the Screenshot Beautifier do?
It turns a plain screenshot into a polished graphic: a colorful gradient or solid background, comfortable padding, rounded corners, a soft drop shadow, and an optional window frame with traffic-light buttons or a browser URL bar. The result downloads as a crisp PNG, ready for social posts, blog articles, documentation, or slides.
How do I add my screenshot?
Three ways: take a screenshot and press Ctrl+V (Cmd+V on Mac) anywhere on the page, drag and drop an image file, or click Choose image. PNG, JPG, WebP, and GIF all work.
Is my screenshot uploaded anywhere?
No. Everything is composited on a canvas inside your browser — nothing is sent to a server. That matters with screenshots, which often show dashboards, customer data, or internal tools.
Will the output stay sharp?
Yes — the export keeps your screenshot's native resolution, so text stays crisp. Very large captures are capped at 4096 pixels on the longest side to keep file sizes manageable.
Can I get a transparent background?
Yes. Choose the Transparent background option and the PNG will contain just the framed, shadowed screenshot — perfect for dropping onto slides or any colored page.
Can I copy the result instead of downloading?
Yes — the Copy image button puts the finished PNG on your clipboard so you can paste it straight into Slack, Twitter/X, Google Docs, or an email.
Is the Screenshot Beautifier free?
Yes, it's completely free to use with no sign-up required.

Seating Chart Generator

https://thedollarweb.com/tools/seating-chart-generator.html Free
+
What does the Seating Chart Generator do?
This tool creates interactive seating charts for events like weddings, conferences, and banquets. You can assign guests to tables, view availability, and export the plan.
How do I add guests?
Options include typing guest names one by one, pasting a bulk list (one per line), or uploading a CSV seating plan. Guests appear in a draggable list, and duplicates are prevented.
How do I assign guests to seats?
Guests can be dragged from the list onto tables and seats. Each table shows available and remaining seats, with warnings if you exceed capacity.
What if I need to rearrange seating?
Seats are draggable, and table dropdowns let you reorder or remove guests. You can also click seats to view guest details and use undo/remove functions.
What file formats are supported for saving or loading?
Download CSV: Exports table, seat, and guest assignments. Download Image: Saves a visual chart snapshot. Upload CSV: Loads past seating arrangements with table/seat mapping.
Does it provide real-time updates?
Yes. The app updates guest counts, remaining seats, and warnings instantly as you add, remove, or rearrange guests.
Is this tool free to use?
Yes — advanced features like CSV import/export, drag-and-drop seating, and image export are completely free to use.

Secret Santa Generator

https://thedollarweb.com/tools/secret-santa-generator.html Free
+
What does the Secret Santa Generator do?
Enter everyone's names, optionally add "can't match" rules (so couples don't draw each other) plus a budget and exchange date, and hit Draw. Everyone is guaranteed a valid match — nobody draws themselves — and you share the results as private reveal links or printable fold-and-pick cards.
How do the private reveal links work without a server?
Each link carries its own match encoded after the # symbol in the URL — the "fragment," which browsers never send to any server. The recipient opens their link, taps to reveal, and sees only their own match plus the budget and date. There's no database of assignments anywhere; the link is the assignment. That's also why the same link always shows the same match.
Can the organizer avoid seeing the matches?
Yes — that's the point of the links. Copy each person's link (including your own) and send them out; the full list is hidden behind a click-to-spoil "Organizer view" you only open in emergencies, like someone losing their link.
How do the can't-match rules work?
Each rule is mutual: add "Alice ↔ Ben" and neither will draw the other — ideal for couples, siblings, or housemates who already exchange gifts. Add as many as you like. If your rules make a valid draw mathematically impossible, the tool tells you plainly instead of spinning forever.
Do you collect email addresses?
No — and that's unusual for this category. The big Secret Santa sites require everyone's email and exist largely to harvest addresses during the holidays. Here, nothing is uploaded, nobody signs up, and you deliver the links yourself by text or chat.
How do the printable cards work?
The print button produces one card per person: their name on the outside, their match (printed upside-down) inside, with a dashed fold line between. Fold each card, then let everyone pick the card with their name on it — the classic hat draw, without the invalid draws.
Can I redo the draw?
Yes — "Draw again" reshuffles freely, and each draw generates fresh links. Just settle on a final draw before sending links out, since a new draw makes the old links obsolete (they'll still show the old match). Your setup is saved in your browser so you can come back and re-copy links anytime.

Sitemap Generator

https://thedollarweb.com/tools/sitemap-generator.html Free
+
What does the Sitemap Generator do?
This tool builds XML sitemaps and index files that follow the official Sitemaps protocol 0.9. It supports large websites by splitting into multiple files of up to 50,000 URLs each.
How do I add URLs?
You can enter a single URL with optional fields like lastmod, changefreq, and priority, paste bulk URLs (one per line, or comma-separated with details), upload CSV-style input, or add your main domain with one click, prefilled with today's date.
Does it handle relative paths?
Yes. When "paths under main domain" is enabled, relative paths (e.g., /tools) are automatically expanded into full URLs using your specified domain.
Can I preview the sitemap before downloading?
Absolutely. The tool shows a live XML preview with options for pretty-printed or minified output.
What extra features are available?
Optional fields toggle for changefreq and priority, Robots.txt helper to copy a ready-to-use sitemap line, import/export JSON for project reuse, and inline editing of table rows with live validation.
How do I save my sitemap?
Click Generate Sitemap to produce files, then download them individually. The tool also shows total file size and URL count.
Is this tool free?
Yes, the Sitemap Generator is completely free to use with no subscription required.

Subtitle Studio

https://thedollarweb.com/tools/subtitle-studio.html Free
+
What does Subtitle Studio do?
It auto-transcribes the speech in any video, lets you edit the timing and wording of each caption, style how the captions look, and then export SRT, VTT, or an MP4 with the captions burned into the pixels — all in your browser.
Does my video get uploaded to a server?
No. Every stage — audio decoding, transcription, editing, and MP4 re-encoding — runs locally in your browser. The speech-to-text model is downloaded once from Hugging Face and cached by your browser; after that, nothing about your video leaves your device.
What speech-to-text model does it use?
OpenAI's Whisper (base.en), released under the MIT license. It runs in your browser via the @xenova/transformers library (Apache 2.0, Hugging Face), which wraps an ONNX build of the model. The first run downloads about 80 MB and caches it; subsequent runs are offline.
Which video formats are supported?
Anything your browser can decode natively — typically MP4 (H.264/H.265), MOV, WebM, and MKV. The tool extracts the audio track via the Web Audio API, so a video with no speech or no audio track simply produces no cues (you can still add cues manually).
How does the burn-in MP4 export work?
It uses the browser's built-in WebCodecs API to re-encode the video as H.264/AAC MP4, drawing each caption directly onto the frames as they pass through. The result is a standard MP4 that plays on any device with the subtitles permanently embedded in the picture — no separate caption file required.
Which browsers support burn-in MP4?
Chrome, Edge, Opera, Safari 16.4+, and Firefox 130+. On unsupported browsers the SRT and VTT exports still work — you just won't see the burn-in button succeed.
How long does burn-in take?
Expect roughly 0.5–1× real time on a modern laptop (a 2-minute 1080p clip takes about 2–4 minutes). The tool seeks through the source video frame-by-frame at 30 fps to keep memory low, which is slower than real-time playback but keeps quality consistent.
Can I edit the auto-generated captions?
Yes. Every cue appears in an editable list where you can change the text, adjust start/end timestamps, add new cues at the current playhead, delete cues, or shift all cues earlier/later by 0.5 seconds to fix sync issues.
How do I style the captions?
Pick a font, color, outline color and thickness, background (none / 50% / 75% / solid), vertical position (top / middle / bottom), and a size percentage that scales with the video so captions look right on any resolution. The preview updates live and the burn-in matches exactly what you see.
Is this tool free to use?
Yes — Subtitle Studio with full transcription, editing, styling, and burn-in MP4 export is completely free to use.

What does the SVG to PNG Converter do?
It converts SVG vector files into standard PNG images (with JPG and WebP as bonus options), entirely in your browser. Drop in one or more SVG files — or paste raw SVG code — choose an output size and background, and download each image individually or the whole batch as a ZIP.
Are my SVG files uploaded anywhere?
No. Your browser already has a full SVG rendering engine built in, so the conversion happens on your own device — the file is read locally, drawn onto a canvas, and encoded as a PNG right there. Nothing is sent to a server, and the tool works offline once the page has loaded.
How do I control the output resolution?
Pick a multiplier (1×, 2×, 3×, or 4× the SVG's natural size) or set an exact pixel width — the height follows the aspect ratio automatically. Because SVG is a vector format, the artwork is re-rendered at the new size rather than stretched, so even a tiny icon exports razor-sharp at thousands of pixels. Output is capped at 8192 px on the longest side.
Is transparency preserved?
Yes — PNG and WebP keep the SVG's transparent background by default (the checkerboard in the preview shows the transparent areas). You can also flatten onto white or any custom color. JPG doesn't support transparency, so it always gets a background.
Can I convert several SVGs at once?
Yes. Drop in as many files as you like — each gets its own preview card — and use "Download all as ZIP" to convert the entire batch with the same settings in one click. Handy for exporting a whole icon set at 2× for retina screens.
Why does my SVG convert with the wrong size or missing parts?
Size: if the SVG has no width/height attributes, its viewBox is used, and if it has neither, browsers default to 300×150 — use the exact-width option to take control. Missing parts: SVGs that reference external images or web fonts can't fetch them during conversion (a browser privacy rule). Embed the images as data URIs or convert text to outlines in your design tool, and everything will render.
Is this tool free?
Yes — completely free, with no sign-up, no watermark, and no file limits.

Table to Markdown Converter

https://thedollarweb.com/tools/table-markdown.html Free
+
What does the Table to Markdown Converter do?
This tool transforms editable tables into Markdown format. You can add or remove rows and columns, edit cells directly, and instantly generate valid Markdown output.
How do I build my table?
Click inside any cell to edit its content. Use the toolbar buttons to add or remove rows and columns as needed. All cells are fully editable.
How do I generate Markdown?
Click Generate Markdown to convert the current table into Markdown. The result appears in a text box below, ready for review.
Can I copy Markdown directly?
Yes. Use the Copy Markdown button to copy the output to your clipboard for quick use in documents, blogs, or GitHub READMEs.
Does it support reset or undo?
A Reset Table button restores the default 2x2 empty table after confirmation. You can also remove individual rows or columns incrementally.
What format does the Markdown follow?
The tool outputs standard Markdown tables with headers, separators, and aligned rows (e.g., | Column1 | Column2 |). Empty cells are preserved as blanks.
Is this tool free?
Yes, the Table to Markdown Converter is completely free to use with no subscription required.

Text to Handwriting

https://thedollarweb.com/tools/text-to-handwriting.html Free
+
What does the Text to Handwriting tool do?
It renders any typed or pasted text as realistic handwriting on paper — ruled with a red margin, plain white, or grid. Pick one of five handwriting styles, an ink color, and a writing size; long text flows onto extra pages automatically, and you download the result as PNG images or a multi-page PDF.
How realistic does it look?
Quite — with "natural variation" on, every word sits slightly above or below the line with subtly varied spacing, the way real ink does, so no two renders are pixel-identical. The five fonts range from neat print (Patrick Hand) to genuinely messy cursive (Homemade Apple). It won't fool a forensic document examiner, but it reads as handwritten at a glance.
Is my text uploaded anywhere?
No. The rendering happens on a canvas in your browser, and the handwriting fonts are served from this site — no requests to Google Fonts or anyone else with your content. Diary entries, letters, and anything personal stay on your device. It works offline once loaded.
Can I print the pages or hand them in?
Pages generate at print resolution (150 DPI, Letter or A4) so they print cleanly. A word of honesty though: use it for creative projects, displays, journaling, and mock-ups — not to misrepresent work as genuinely handwritten where that actually matters, like signed documents or assignments where handwriting is the point.
How do multiple pages work?
Text wraps and flows exactly like ink on paper — when a page fills, the rest continues on the next one. Use the ‹ › arrows to preview each page, then download the current page as PNG, every page in one PDF, or all pages as a ZIP of PNGs.
Which characters and languages are supported?
Standard Latin text, including accented European characters (é, ñ, ü, and so on) in most of the styles. Other alphabets — Cyrillic, Arabic, CJK — aren't covered by these handwriting fonts and will fall back to a plain typeface.
Are the handwriting fonts licensed for this?
Yes — all five (Caveat, Homemade Apple, Patrick Hand, Kalam, Shadows Into Light) are released under the SIL Open Font License 1.1, self-hosted on this site, and credited on the licenses page. The images you generate are yours to use, commercially included.

Text-to-Speech Studio

https://thedollarweb.com/tools/text-to-speech.html Free
+
What does the Text-to-Speech Studio do?
It turns any text into a natural-sounding voiceover using an AI voice that runs entirely in your browser. Type or paste a script, pick from ten American and British voices, adjust the speed, preview the audio, and download it as MP3 or WAV.
Is my text uploaded to a server?
No. The AI voice engine (the open-source Kokoro model, about 90 MB) downloads once into your browser's cache, and all speech is generated on your own device. Your script never leaves your computer — there's no account, no character metering, and no usage log.
Does it work offline?
Yes. After the one-time engine download, the voices are cached by your browser and the tool generates speech with no internet connection.
How long can my script be?
There's no character limit. Long scripts are read sentence-by-sentence with natural pauses, and a progress bar tracks the generation. Speed depends on your device — expect roughly real-time on a modern laptop, slower on older hardware.
What languages and formats are supported?
The voices currently speak English with US and UK accents. Output is 24 kHz mono audio, downloadable as a 128 kbps MP3 or an uncompressed WAV.
Can I use the audio commercially?
Yes. The Kokoro voice model is Apache-2.0 licensed, and audio you generate is yours to use — in videos, podcasts, courses, or client work.
Is the Text-to-Speech Studio free?
Yes, it's completely free to use with no sign-up required.

Tier List Maker

https://thedollarweb.com/tools/tier-list-maker.html Free
+
What does the Tier List Maker do?
It lets you rank anything into the classic S-through-F tier rows. Add text chips or images, drag them into tiers (and reorder within a tier), customize the labels and colors, then download the finished ranking as a PNG to share in a group chat, Discord, or social post.
How do I add items to rank?
Three ways: type a text item and press Enter, upload one or more images (they're auto-cropped into square tiles), or paste an image straight from your clipboard with Ctrl+V.
Can I customize the tiers?
Yes — click a tier label to rename it (anything from "God tier" to "Cursed"), click the color dot to cycle its color, use the arrows to reorder rows, and add or remove tiers freely. Removing a tier returns its items to the unranked pool, so nothing is lost.
Does it work on a phone?
Yes. You can drag with a press-and-hold (a quick swipe still scrolls the page), or use the tap-to-place shortcut: tap an item to select it, then tap the tier you want it in.
Are my images uploaded anywhere?
No. Unlike template-based tier list sites where uploaded images become public templates on their servers, everything here — the items, the images, the ranking, the PNG export — happens entirely in your browser. Your work also autosaves locally so you can come back to it.
Is there a watermark?
There's no watermark over your items — just a small "Created with The Dollar Web" note beneath the board on the export. The tool is completely free with no sign-up.

Time Capsule Notes

https://thedollarweb.com/tools/time-capsule-notes.html Free
+
What is Time Capsule Notes?
Write a note, pick a future date, and download a sealed capsule — a single self-contained file, encrypted with AES-256 in your browser. Open the file any time and it shows a live countdown; on the date you chose, it opens itself and reveals the note. No account, no server, and the capsule works offline forever.
Can someone open it before the date?
We're honest about this where other tools aren't: the date lock is a sealed envelope, not a bank vault. The capsule refuses to open early, which is exactly right for letters to future-you and gifts — but a skilled programmer could pry the built-in key out of the file. If you need real secrecy, add the optional passphrase: then the encryption key is derived from it and never exists in the file, and nobody can open the note without it.
What happens if I forget the passphrase?
The note is gone — permanently. We never see or store the passphrase, so there is no reset or recovery. That's the price of real encryption. For gift capsules, a good pattern is to give the passphrase to someone you trust to hand over on opening day.
Will the capsule still open years from now?
That's the design goal: the capsule uses only plain HTML and the Web Crypto API built into every modern browser — no libraries, no fonts to download, no connection back to us. Even if this website vanished, every capsule ever made would keep working. Keep a copy wherever you keep files you care about.
Is my note uploaded anywhere?
Never. The note is encrypted on your device, the capsule downloads straight from your browser, and opening it happens entirely on the device it's opened on. The only unencrypted text in the file is the optional cover message you choose to put on the envelope.
What do people use it for?
Letters to your future self, notes for a child to open at 18, New Year's predictions sealed until next December, anniversary letters between partners, advice-to-self before a big life change, and "read when I'm gone" letters sealed with a passphrase a loved one holds.

Time Card Calculator

https://thedollarweb.com/tools/time-card-calculator.html Free
+
What does the Time Card Calculator do?
It adds up your work week. Enter each day's clock-in and clock-out times and any unpaid break, and it computes daily hours, the weekly total (in both decimal hours and hours:minutes), the regular/overtime split, and — if you add your hourly rate — your gross pay. Then print it as a clean, signable timesheet.
Does it handle overnight shifts?
Yes. Clock in at 10:00 PM and out at 6:00 AM and it correctly counts 8 hours, flagging the day with a small "overnight" badge so you can double-check it's intentional.
How is overtime calculated?
Hours beyond the weekly threshold — 40 by default, the U.S. federal standard — are split out and paid at 1.5× your rate. You can switch the threshold to 44 or turn overtime off. Note that some places have daily overtime rules (like California); this tool applies the common weekly-threshold model.
What is payroll rounding?
Many employers round each day's time to the nearest 5, 6, or 15 minutes — 6-minute rounding is popular because it produces clean tenths of an hour. Pick your employer's convention from the dropdown and your totals will match the paystub.
Why decimal hours? What's 8:20 as a decimal?
Payroll systems use decimal hours so they can multiply by a pay rate. The conversion is minutes ÷ 60: 8 hours 20 minutes is 8.33, and 7:30 is 7.5. The tool shows every total in both formats so nothing gets lost in translation.
Can I print or save the timesheet?
Yes — the Print button produces a one-page timesheet with your name, the week, each day's hours, totals, and employee/supervisor signature lines, with all the site chrome stripped out. Choose "Save as PDF" in the print dialog to keep a digital copy.
Is my schedule uploaded anywhere?
No. Your hours and pay rate are between you and your employer — everything computes on your device, and entries save only to your own browser so this week's card is still here tomorrow. Reset starts a fresh week.

Timeline Generator

What test durations are available?
You can choose from four test lengths: 30 seconds for a quick check, 1 minute for standard testing, 2 minutes for moderate endurance, or 5 minutes for comprehensive assessment. Select your preferred duration before starting the test.
How does the test work?
After entering your name and email, you'll type randomly generated words that appear on screen. The timer starts as soon as you begin typing. Words turn green when correct and red when incorrect, allowing you to see your accuracy in real-time.
What metrics are tracked?
The tool tracks three key metrics: Words Per Minute (WPM), accuracy percentage, and total words typed. WPM updates in real-time as you type, giving you instant feedback on your performance.
Does it detect errors and corrections?
Yes. The tool accurately tracks when you misspell a word and recognizes when you correct it and get back on track. This smart error detection ensures your WPM and accuracy scores reflect your true typing ability.
What's included in the certificate?
Your downloadable PDF certificate includes The Dollar Web logo, your name and email, test duration, WPM score, accuracy percentage, total words typed, test date, and a clickable "Powered by The Dollar Web" link. The certificate features professional design with your brand colors.
How do I download my certificate?
After completing a test, click the "📄 Download Certificate" button on the results screen. The certificate is saved as a high-quality PDF with your name in the filename for easy identification.
Why do I need to enter my email?

Unit Converter

https://thedollarweb.com/tools/unit-converter.html Free
+
What does the Unit Converter do?
Pick a category — length, weight, temperature, volume, area, speed, time, or digital storage — type a value, choose the unit it's in, and instantly see it converted into every other unit in that category at once. Click any result to copy it.
Is my data sent anywhere?
No. All conversions run in your browser using exact conversion factors, so there's no network request and nothing you type leaves your device.
Does it handle temperature correctly?
Yes. Celsius, Fahrenheit, and Kelvin use the proper conversion formulas (not a simple multiplier), and negative values work — so sub-zero temperatures convert accurately.
What's the difference between KB and KiB for data?
KB, MB, GB, and TB are decimal units (powers of 1000), while KiB, MiB, GiB, and TiB are binary units (powers of 1024). The converter includes both so you can translate between how drives are advertised and how operating systems report sizes.
Is the Unit Converter free?
Yes, it's completely free to use with no sign-up required.

USA Heat Map Generator

Can I choose the colors and scale?
Yes. Pick from several sequential and diverging color schemes, and let the map auto-scale to your numbers or set your own minimum and maximum for consistent comparisons. A legend updates automatically.
Does it include Alaska, Hawaii, and DC?
Yes — all 50 states plus Washington, D.C. The map uses an Albers USA projection with Alaska and Hawaii shown as insets. Leave any state blank to display it as "no data."
How do I save or share the map?
Click "PNG" to download a high-resolution image with the title and legend included, or "Export CSV" to save your numbers. Hover a state to see its value, or click it to jump to its input.

It records audio from your microphone right in the browser, shows a live level meter while you record, lets you pause and resume and play it back, and downloads the result as an MP3 file.
Can I download my recording as an MP3?
Yes. After you stop, choose 96, 128, or 192 kbps and click "Download MP3" — the audio is encoded to MP3 in your browser. You can also grab the original (WebM/Opus or MP4) file if you prefer.
Is my recording uploaded anywhere?
No. The microphone audio is captured, played back, and converted to MP3 entirely on your device. Nothing is uploaded or stored on a server, so it's genuinely private.
Why does it ask for microphone permission?
Recording audio requires your permission to use the microphone — that's a browser security feature. If you blocked it by accident, allow microphone access for this site in your browser settings and reload.
Is it free?
Yes, completely free with no sign-up. It works in modern browsers that support audio recording.

Word & Character Counter

https://thedollarweb.com/tools/word-counter.html Free
+
What does the Word & Character Counter do?
As you type or paste text, it shows live counts of words, characters (with and without spaces), sentences, and paragraphs, plus estimated reading and speaking time, unique words, and your most-used keywords. A "Fits in…" panel checks your text against common limits like tweets, SEO titles, and meta descriptions.
Is my text sent anywhere?
No. All counting happens in your browser as you type — nothing is uploaded or logged. That keeps drafts, cover letters, and unpublished writing private.
How is reading time calculated?
Reading time assumes about 200 words per minute and speaking time about 130 words per minute — typical averages. They're estimates to help you plan blog posts and scripts, not exact measurements.
What is keyword density and the "ignore common words" option?
Keyword density ranks the words you use most and shows how often each appears. Turning on "ignore common words" filters out filler like "the", "and", and "to" so the meaningful terms rise to the top — useful for SEO and spotting repetition.
Is the Word & Character Counter free?
Yes, it's completely free to use with no sign-up required.

Chart Creator

https://thedollarweb.com/tools/chart-creator.html Free
+
What does the Chart Creator do?
It lets you build polished charts from a small, editable spreadsheet inside your browser. Pick a chart type, fill in labels and values, customize titles, axes, legends, colors, and fonts, then download a PNG or copy the chart to your clipboard.
What chart types are supported?
Pie, doughnut, polar area, bar (vertical), horizontal bar, line, area, and radar. All of them work with relatively small datasets, which makes them ideal for slide decks, reports, and dashboards rather than raw exploration of large data.
How do I enter my data?
There's a built-in editable spreadsheet in the tool. Type your category labels in the first column, then enter values for each series in the remaining columns. You can add or remove rows and series, drag swatches to change colors, and rename series headers inline.
Can I use more than one series?
Yes. Bar, line, area, and radar charts all support multiple series — each series gets its own column in the spreadsheet, its own legend entry, and its own editable color. Pie, doughnut, and polar charts use one series with a separate color per slice.
How customizable is the look?
Very. You can edit the chart title, subtitle, axis titles, legend position, font family, background color, label text color, donut cutout, gridlines, data labels, stacking, and line smoothing. Eight built-in color palettes (Default, Pastel, Ocean, Sunset, Forest, Vibrant, Monochrome, Grayscale) can recolor every slice or series in one click.
How do I export my chart?
Download a high-resolution PNG, copy the chart directly to your clipboard for pasting into Slack, Google Docs, or a slide, or export the underlying data as a CSV if you'd like to share or reuse the dataset.
Is my data uploaded anywhere?
No. The whole tool runs in your browser using Chart.js — your numbers, labels, and chart never leave your device, so it's safe for client data, financial figures, and internal metrics.
Is the Chart Creator free?
Yes, the Chart Creator is completely free to use with no subscription required.
