OSS Document Scanner

What OSS Document Scanner is

OSS Document Scanner is a free, open-source mobile app for capturing, editing, organizing and exporting scanned documents. Available for Android and iOS, it can detect page edges automatically or use manual capture, and batch scanning can combine multiple pages into one document. After capture, scans can be cropped, rotated and enhanced with image filters. On-device OCR can add searchable text to exported PDFs. Export options include standard PDFs, OCR PDFs, JPEGs and PNGs; documents can also be shared, saved or printed. Optional WebDAV sync supports Nextcloud, ownCloud, Synology NAS, QNAP NAS and other WebDAV servers. The app processes documents on-device and does not upload them unless sync is configured; its FAQ says there is no analytics or tracking. For sync, credentials use the platform keychain, configured HTTPS protects data in transit, and local storage uses device encryption. Backups are ZIP files and are not encrypted by default. Android downloads are listed through Google Play, IzzyOnDroid, GitHub Releases or Obtainium, while iOS distribution is through the App Store. The stated minimum versions are Android 7.0 (API 24) and iOS 13.0. The maker identifies Martin Guillon, an independent mobile application developer and consultant based in France working under Akylas.
