Scangrin: Offline PDF Scanner

Scangrin turns paper into clean, searchable PDFs on your phone. Scanning, text recognition (OCR) and PDF creation all happen on your device. There is no account to create, no watermark on your pages and no limit on scans or pages. Every feature is free.

Point your camera at a page and Scangrin finds the edges, straightens the shot and cleans it up. Scan one page or a whole stack, put the pages in order, then save or share a PDF.

PRIVACY
Your documents and their text stay on your device unless you choose to save or share them somewhere else. Scangrin has no servers of its own, so nothing is sent to us to process your documents. Android cloud backup is set to leave your documents out. Ads are provided by Google AdMob, which collects some device data. Scangrin also uses Google Firebase for usage statistics, which you can turn off in Settings, and for crash reports, which stay off unless you turn them on. Neither includes your documents or their text. The Data safety section and our privacy policy explain what is collected.

FREE, WITH ONE AD AFTER YOU SAVE
To keep every feature free, Scangrin shows one ad after some saves or shares. You will never see an ad while you scan, before you have seen your document, or on your first two saves. You can choose to watch one ad to switch ads off for 24 hours, or make a single one-time purchase to remove them. There is no subscription and no trial.

HOW TO SCAN A DOCUMENT TO PDF
1. Open Scangrin and tap Document
2. Hold your phone over the page and Scangrin captures it
3. Add more pages or adjust the crop and filter
4. Save a searchable PDF, or share it
