A scanner that lives in your browser

You don't need a flatbed scanner or an app to digitise paper. Take a photo of a page, receipt, form, or business card with any camera, drop it here, and this tool turns it into a clean, square-on scan you can save as a PDF or PNG.

Everything runs in the browser: it finds the document's four corners, remaps the angled photo into a flat rectangle, and applies an enhance filter so text is crisp and the paper looks white. Nothing to install, no account, no watermark.

How to scan a document

  1. Add a photo. Drag a photo of the page onto the tool above, choose a file, or paste it from your clipboard.
  2. Set the corners. Tap Auto-detect edges, or drag the four corner handles to the edges of the document.
  3. Enhance. Pick Magic, Black & White, Grayscale, or Original to clean up the page.
  4. Save as PDF. Choose PDF (A4, Letter, or fit) or PNG, then download your scan.

Get the cleanest scan

Shoot the page on a plain, contrasting surface in even light, filling most of the frame. Good contrast between the paper and the background helps auto-detect find the edges, and even lighting makes the Black & White and Magic filters look their best.

よくある質問

Is the document scanner free?

Yes — completely free, no watermark, no sign-up. Scan as many documents as you like and save them as PDF or PNG.

Do I need to install anything?

No. It runs entirely in your web browser on phone or computer — there's nothing to download or install.

Can I save multiple pages?

Each scan exports a single-page PDF or image. To combine several pages into one PDF, scan each and merge them with our Image to PDF tool.

Where is my image processed?

The scan is created in your browser, so the new file is created on your own device. How any data associated with the tool is handled is described in our privacy policy.
