Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026

OSS Document Scanner is a free, open-source mobile scanning app from Akylas for iOS and Android. It is designed for people who want to capture paper documents with a phone or tablet camera, then edit, enhance, organize, and export them. Automatic edge detection supports faster capture, while manual capture provides an alternative when automatic framing is not suitable. Batch and multipage scanning make it appropriate for receipts, forms, notes, and other document sets that need to remain together.

Its strongest feature depth is the document workflow after capture. Users can crop, rotate, reorder, and merge pages, apply image enhancement filters, and adjust brightness or contrast. Offline OCR models can produce searchable PDFs, while exports are available in PDF, JPEG, and PNG formats. Generated PDFs can also receive password protection. The published feature set covers the core path from camera capture to a finished, searchable document without requiring AI features or an online OCR service.

Platform and ecosystem fit depend on the storage setup a user prefers. OSS Document Scanner supports WebDAV, Google Drive, OneDrive, and local folder synchronization, giving the app options for personal storage workflows. The free plan is open source, ad-free, and includes document scanning and OCR support; no paid tier is presented. It is a strong choice for users who want mobile scanning, offline OCR, and control over how files are synchronized. Users seeking AI-powered processing or a broader document-management platform should look elsewhere.
