The OSS Document Scanner is a free and Open Source app to transform your mobile device into a powerful document scanner.




Google Lens lets you search what you see, get things done faster, and understand the world around you—using just your camera or a photo.




OpenScan is an open source app that enables users to scan hardcopies of documents or notes and convert it to PDF or JPEG files. Its motto is "No ads. No data collection. We respect your privacy.".



The Adobe Scan scanner app turns your device into a powerful portable scanner that recognizes text automatically (OCR) and allows you to save to multiple file formats including PDF and JPEG.








MakeACopy is an open-source document scanner app for Android that allows you to digitize paper documents with OCR functionality. The app is designed to be privacy-friendly, working completely offline without any cloud connection or tracking.




PhotoScan lets you create enhanced digital scans of your old photos, with automatic edge detection, perspective correction, and smart rotation.




Main point of this app is to scan or select existing PDF documents simply using intent or chooser. Other apps require payment to access their api/sdk or simply don't have a possible way to do it. So they rely on switching between an app ,file chooser and a scanner.









OSS Document Scanner is more lightweight, and has better filters. It condenses the files similarly as CamScanner, but the text is more clear.
The only problem is that for my phone (GrapheneOS), I have to take photos with camera and import them in the app, because for whatever reason it makes the images blurry when I take the photo in the app itself. This may be because of my Android operating system.
But it's smaller, open-source, and outputs better images (textbook pages).
