Document Scanner

From a crooked photo to a clean scan

A phone photo of a page is almost always shot at a slight angle, with shadows and a distracting background. You mark the four corners of the document, and the tool computes a perspective correction that maps that skewed shape back into a straight, upright rectangle — the same technique a dedicated scanner app uses.

It then cleans up the lighting so the page reads like it came off an office scanner rather than out of a camera.

Filters that make text sharp

Black & White mode uses an adaptive threshold, judging each part of the page against its own surroundings, so uneven light and shadows do not wash out one side. Text comes out dark and solid on a clean white background. Grayscale keeps shading for pencil notes and photos, and Color preserves coloured forms, stamps, or highlighter.

Multi-page PDFs

Scan a whole document by processing each page and adding it to the stack, then export one tidy PDF — ideal for receipts, multi-page forms, contracts, and IDs you need to email or file. There is no separate merge step.

Private by default

The paperwork people scan is often the most sensitive they own — IDs, signed forms, medical or legal documents. Because every step runs on your device, none of it is uploaded. There is no app to install and no account to create.

Frequently asked questions

Do I need to install an app?

No — it runs in your browser on phones and computers, so there is nothing to download and no account to create.

Is my document uploaded?

No — the photo is processed on your device in your browser, and nothing is sent to a server, so it is safe for IDs, contracts, and private paperwork.

How do I get a straight, flat scan?

Drag the four corner markers precisely onto the edges of the document in your photo; the tool flattens that area into a rectangle, removing the angle and perspective. Accurate corners are the key to a good result.

My scan came out skewed or cropped wrong — why?

Almost always the corner markers were not right on the page edges. Re-open the photo and place each marker carefully on a corner before flattening.

Can I scan more than one page?

Yes. Process each photo and add it as a page, then export a single multi-page PDF — no separate merge step needed.

What do the Color, Grayscale, and B&W modes do?

They control the scan look — Color keeps the original, Grayscale removes colour, and Black & White uses an adaptive threshold to boost contrast for crisp text like a real scanner.
