Clean Scan
What Clean Scan is
Clean Scan is a free, open-source Android app for turning paper documents into PDF files. It automatically detects document edges for cropping and can enhance image quality, including scans made from low-light or poor photos. Optical character recognition extracts text from images, while categories help users organise documents for management and search. Completed scans can be shared by email, WhatsApp, Messenger, or links to social networks. The project is released under the Apache License, Version 2.0, and uses OpenCV Android, which the maker identifies as BSD-licensed. Clean Scan is presented only as an Android document scanner; no iOS app is listed. The maker’s website links to Google Play as the download route, although that link returned a 404 when opened. Available maker pages provide no security, privacy, compliance, or support-contact details. The maker page lists Clean Scan App copyright as 2018 Shouvik Basu. For Android users, its listed workflow covers capture, automatic cropping, image improvement, PDF creation, text recognition, categorisation, and sharing without a charge.
