The OSS Document Scanner is an Open Source app to scan all your documents. You either scan using your camera or by importing an image. The app will automatically detect you document within the photo and will crop the image.






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.".



Unfortunately no filters like "real" scan apps; so this is basically the original photo
Very fast and extremely easy to use. No ads or privacy scandals. Free and open source. Scans, crops, and touches up documents as well as CamScanner.


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.








Simple UI and no hassle when using for free
Its user interface is very easy to use.


Scan Thing is the quickest way to capture and save anything around you. Scan Thing is available on iOS, iPadOS, and MacOS.




Scanner Pro turns your iPhone into portable scanner in your pocket. It lets you scan multipage documents, email them and even upload to Dropbox, MobileMe iDisk or any other WebDAV enabled server.




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.





The document management functions are very good.






PDNob Image Translator instantly extracts and translates text from images and scans, making it easy to access information across languages.



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).
