Free PDF Tools

Eighteen focused tools that handle every PDF job you will ever hit: merge, compress, convert, split, sign, fill, scan, redact, protect. Each one runs entirely in your browser, so the contract, lease, or medical record you are working on never touches a server.

100% in your browser No uploads, ever No sign-up, no limits Free, no watermarks

Every PDF tool, ranked by what people reach for most

The list runs from the jobs almost everyone needs (merging and shrinking files) down to the specialist tools that save your day twice a year. Every one of them is free, works offline once loaded, and never sees your document.

  1. 1

    PDF CombinerMost used

    Merge any number of PDFs into one document. Drop, drag into order, download.

    This is the tool people come back to every week. Drop in your files, drag them into the right order, and download a single merged PDF. There is no page cap and no "go premium to merge" wall, because there is no server doing the work. Your machine does it, which also means a stack of signed contracts or bank statements gets merged without any of them leaving your computer.

    PDF CompressorMost used

    Shrink a PDF that is too big to email or upload, without wrecking the text.

    Every portal and inbox has a size limit, and every scanner seems determined to blow past it. The compressor squeezes down the images and embedded data that make PDFs heavy while keeping the document readable, which is usually the difference between "attachment too large" and sent. Files with lots of photos see the biggest drops.

    PDF SplitterMost used

    Pull exact pages or page ranges out of a big PDF into a clean new file.

    Type the pages you want, like 1-3, 7, 12-15, and get a new PDF with just those pages. It is the fastest way to send someone a single chapter, share one clause of a contract, or peel an appendix off a 200-page report without forwarding the whole thing.

    File to PDF Converter

    Turn images, Word documents, and other everyday files into proper PDFs.

    Whatever you have, whoever is asking wants it as a PDF. This converter takes photos, Word documents, and other common formats and produces a clean, predictable PDF, with the option to stamp text, notes, or a watermark on the way through. Photograph a paper form with your phone, convert it here, and you have something official enough to submit.

    PDF to Images

    Export PDF pages as high-quality PNG, JPG, or WebP images at any resolution.

    Slides, posters, and one-pagers often need to live outside the PDF: in a presentation, a social post, or a website. Pick your format and resolution, then download a single page or every page bundled into a ZIP. The rendering happens at full quality on your machine, so text stays crisp even at large sizes.

    PDF Form Filler

    Type into fillable PDF forms, or drop text anywhere on a form that is not fillable.

    Real fillable forms are detected automatically: text boxes, checkboxes, radio buttons, dropdowns, all typeable. And for the forms that are really just flat scans, you can place your own text exactly where each answer belongs and drag it into position. Flatten when you are done and the result is locked and ready to send. Tax forms, school forms, and intake paperwork stay on your device the whole time.

    PDF Signature

    Draw or type your signature and place it precisely on any page.

    The print-sign-scan ritual ends here. Create your signature once, position it exactly where the document needs it, and download the signed PDF. Combined with the Form Filler, it covers the entire "please sign and return" email without a sheet of paper involved. And unlike e-sign services, there is no account, no workflow emails, and no third party storing a copy of your signature.

    PDF ModifierAll-in-one

    The everything tool: combine, split, reorder, add text, draw, highlight, and stamp page numbers in one workspace.

    When a document needs more than one kind of surgery, start here instead of hopping between tools. The Modifier rolls merging, splitting, page reordering, text stamping, freehand drawing, and highlighting into a single editing session, so a messy multi-step cleanup becomes one pass and one download. It is the closest thing on this page to a full PDF editor.

    PDF Page Deleter

    Click the pages you do not want and download the PDF without them.

    Every page renders as a thumbnail. Click the blank scans, the duplicate pages, or the "this page intentionally left blank" filler, and download a trimmed document. It is the two-click answer to a job that used to mean rebuilding the whole file.

    PDF OCR

    Turn a scanned PDF into searchable, copyable text without it leaving your device.

    A scan is just a photograph of a page: you cannot search it or copy from it. OCR reads every page and gives you the text back, searchable inside the tool and exportable as TXT, JSON, or a searchable PDF. Running character recognition locally matters most exactly where OCR is most useful: old records, IDs, and archives full of personal information.

    PDF to Word

    Turn a PDF into an editable Word document you can fix up in Word or Google Docs.

    Someone sent you a PDF and you need to change three sentences. Instead of retyping the whole thing, convert it to a .docx you can open in Word or Google Docs. It does its best work on simply formatted documents: paragraphs, headings, bold and italic text, and hyperlinks come through, while heavily designed layouts may need some cleanup afterward. Because the conversion runs on your device, it is safe for offer letters, agreements, and anything else with your personal details.

    PDF Password Protector

    Lock a PDF with a password using standard AES-256 encryption.

    Before you email a document with salary figures, bank details, or a scan of your ID, put a password on it. The protector applies the standard AES-256 encryption that PDF readers everywhere understand, so the recipient just types the password you share with them separately. Encrypting locally is the whole point: a password added by an upload site protects you from everyone except that site.

    PDF Page Rearranger

    Drag page thumbnails into a new order and download the fixed document.

    For the scan that came out backwards, the report with the summary buried on page 9, or the packet that needs its cover page moved to the front. Every page shows as a thumbnail; drag them into the order you actually wanted and download. No page numbers to type, just move what you can see.

    PDF Watermarker

    Stamp DRAFT, CONFIDENTIAL, or any text across every page, styled your way.

    Mark a document's status before it starts circulating. Set the wording, color, opacity, and position, and the watermark lands consistently on every page. A visible DRAFT has stopped more premature forwards than any email disclaimer ever has, and a copyright line across sample pages protects work you share publicly.

    PDF Page Numbers

    Add page numbers with full control: numeral style, position, font, and where counting starts.

    Merged documents lose their numbering, and submissions often require it in a specific format. Choose Arabic or Roman numerals, pick the corner or center position, set the font, size, and color, use a label format like "Page 3 of 12", and tell it which page to start counting from so your cover page stays clean.

    PDF Redactor

    Permanently remove sensitive information, not just draw a black box over it.

    There is a famous failure mode where "redacted" text is just a black rectangle sitting on top of perfectly copyable words. This tool does it properly: the redaction is baked in and irreversible, so the account numbers, names, or figures underneath are actually gone from the file. For documents this sensitive, processing them locally instead of uploading them is not a nice-to-have.

Questions people ask before trusting a PDF site

Do my PDF files get uploaded to a server?
No, and this is the entire point of the site. Every tool on this page does its processing in your browser with local code. Your document is opened, edited, and saved on your own device; it never travels over the network. You can watch the network tab in your browser's developer tools while using any tool and see for yourself.
Are these tools really free? What's the catch?
All 18 PDF tools are free with no sign-up and no watermarks stamped on your output. The site offers an optional premium plan that adds extra features on some tools and guarantees unlimited use, and that is the business model: useful free tools, a paid tier for people who want more. Your files are never part of the equation.
Is there a file size or page limit?
No artificial one. Upload-based sites impose limits because processing your file costs them server money. Here your own computer does the work, so the practical ceiling is your device's memory, which handles documents far bigger than the free tiers of the well-known PDF sites allow.
How do I merge several PDFs into one file?
Open the PDF Combiner, drop your files in, drag them into order, and download the merged result. It is the most-used tool on this page, which is why it sits at number one.
How do I make a PDF smaller so it sends by email?
Use the PDF Compressor. It shrinks the images and embedded data that make files heavy while keeping the text readable, which is usually all it takes to get under a 10 MB or 25 MB attachment limit.
Can I edit a PDF without paying for Adobe Acrobat?
Yes. The PDF Modifier handles everyday editing: adding text, drawing, highlighting, combining, splitting, reordering, and page numbers. For a specific job, the focused tool is usually faster: the Form Filler for forms, the Signature tool for signing, the Page Deleter for trimming.
How is this different from Smallpdf, iLovePDF, or Adobe's online tools?
Those services process your document on their servers, which means your file is uploaded, handled by their infrastructure, and subject to their retention policies. These tools do the same jobs without your file ever leaving your device. That is a real difference for contracts, medical records, financial statements, and anything else you would not want sitting in a stranger's cloud.
Do the tools work offline?
Mostly, yes. Once a tool's page has loaded, the processing code is already on your device, so most tools keep working if your connection drops. That is a useful side effect of doing everything locally.
