Scan to PDF — Offline Scanner

Scan to PDF is a document scanner that works right on your phone. Point the camera at a sheet: the app finds its edges, straightens the page and makes the paper white. Shadows and yellow light are gone. No account, no ads, and no internet permission at all.

WHAT IT DOES

A live frame shows the sheet it has found. You press the button when you are ready: no automatic shots going off by themselves.
Uses the main camera: tap to focus, flash, the whole frame sharp.
Three looks for every scan: Document (clean black and white), Color (white paper, stamps and pen stay in colour) and As shot.
Crop by the corners and the middles of the sides, with a magnifier under your finger. Rotate, retake a page, delete, change the order by holding a thumbnail.
Pinch or double-tap to zoom a page. Hold it to compare with the original photo.
Photos and PDFs you already have are welcome too: a photo of a contract from a chat is cleaned just like a scan, and pages of a digital PDF are kept whole.
Saves Scan__.pdf in Downloads / Scan to PDF. Open it, save it anywhere, share it or print it on a printer in your network.

HOW IT WORKS

Tap Scan, point the camera at the sheet, press the button for each page, then Done.
Pick a look, fix a corner if you need to, tap Save PDF.
Share the result, print it, or open it in the next app: make the file smaller, get the text, add a stamp or signature.

Best results: a sheet on a darker background, in even light.

Camera: the app asks for the camera only when you tap Scan. Photos stay on the phone and are used only to make your PDF.
