How do I scan a document without a scanner app?

Open this page on your phone, tap Take a photo, and your camera opens directly. Snap the document, drag the four corners onto the page edges, pick the scan filter, and download the PDF. No app install, no account, and the photo never leaves your phone.

Are my documents uploaded like they are with scanner apps?

No, and that is the point. Popular scanner apps have repeatedly made headlines for what happens to documents on their servers. Here the perspective correction, the filters, and the PDF assembly all run in your browser, so contracts, IDs, and receipts never travel anywhere.

How does the black-and-white scan filter work?

It uses adaptive thresholding: every pixel is compared to the brightness of its own neighborhood rather than one global cutoff, which is how real scanners make text crisp and backgrounds white even when the photo has shadows or uneven lighting.

Can I scan multiple pages into one PDF?

Yes. Each photo becomes a page with its own straightening and filter, pages can be reordered or deleted, and the export produces a single PDF in A4, Letter, or a size matched to the photos.

Document Scanner Online Free: Photo to PDF in Your Browser, No App

A Real Document Scanner, Minus the App and the Upload

Scanner apps have a dirty secret: the "free" ones process your paperwork on their servers, and paperwork is the most sensitive thing you own: leases, IDs, medical forms, contracts, tax letters. This scanner does everything the apps do, in the browser, on your device. Tap Take a photo and your phone camera opens directly; snap the page, drag four corners onto its edges, and a true perspective correction squares it up like it was shot dead-on. The black-and-white scan filter then does what real scanners do, crisp text on clean white, even when the photo had shadows.

Stack as many pages as you need, reorder them, give each its own look, and export one PDF in A4, Letter, or a size matched to your photos. On a phone you can share the PDF straight into email or a chat, and any single page can be saved to your photos as an image. Nothing installs, nothing uploads, nothing is stored after you leave.

What it does

Camera-first: on phones, one tap opens the camera; on desktops, pick or drop image files, several at once.
Perspective straightening: drag four corners onto the page and the warp makes an angled shot rectangular, with an automatic first guess at where the page is.
Scan filters: Original, Enhanced (contrast and color cleanup), Grayscale, and an adaptive black-and-white that keeps text sharp under uneven lighting.
Multi-page PDFs: add, reorder, delete, and per-page filters, exported as one file.
Rotate: sideways photos fix with one tap, and phone photos load right-side-up automatically.
Share or save: download the PDF, share it straight to another app on phones, or save any page as an image.

Good to know

Light the page from the front and shoot from slightly above; the corner handles forgive the rest.
The B&W scan filter is the one to use for text documents you plan to print or email; Enhanced is better for anything with photos or color.
Receipts work great: crop tight with the corners and the adaptive filter makes thermal-paper text legible again.
Pages render into the PDF at high resolution (up to about 2200px on the long side), so zoomed-in text stays readable.
Nothing is kept after you close the page; export the PDF before you leave.

Common questions

How do I scan a document with my phone for free?

Open this page, tap Take a photo, and snap the document; the camera opens directly with no app install. Drag the corners onto the page edges, pick the B&W scan filter, and download or share the PDF. The whole thing takes under a minute.

How do I turn a photo into a PDF?

Add the photo, straighten if needed, choose a filter, and press Download PDF. Multiple photos become multiple pages in one file, in the order shown in the page list.

Is this safer than scanner apps?

Yes, structurally: there is no server to trust. The straightening, filtering, and PDF assembly all run in your browser, so a lease or an ID card never travels anywhere. When you close the tab, nothing remains.

Why does the black-and-white filter look better than just desaturating?

It thresholds each pixel against its own neighborhood (adaptive thresholding), which is how real scanners produce black text on white paper even when half the photo is in shadow. A simple grayscale keeps the shadows; the scan filter removes them.

Can I scan several pages into one PDF?

Yes. Each photo becomes a page with its own corners and filter; reorder or delete pages in the list, then export a single PDF in A4, Letter, or a size matched to the photos.
