Document & Receipt Scanner

Drag the four corners of a photo to flatten it into a clean scan — no uploads, ever.

How to use

  1. Take a photo or upload an existing image of the document.
  2. Drag each corner pin onto the actual edges of the document — use the magnifier that appears while dragging for precision.
  3. Tap "Flatten" to get a straightened scan, and apply the B&W filter if you like.
  4. Download as JPG or PDF.

FAQ

Q. The corners are hard to line up precisely.

A. While dragging, a magnified loupe appears above your finger/cursor — use it to see exactly where the edge is.

Q. Can I process multiple pages at once?

A. Currently one image at a time.

Q. Is my photo uploaded anywhere?

A. No, both the perspective correction and the B&W filter are computed entirely in your browser.

Q. The result looks lower resolution than I expected.

A. Resolution is capped for speed and mobile memory safety — this is still plenty sharp for reading receipts and documents.

Why this stays private

The whole process — reading the photo, correcting the perspective, applying the black & white filter, and building the JPG/PDF — runs entirely in your browser using Canvas math. The image is never sent to a server, so it works even on a huge photo and even offline once the page has loaded.
