Free Android Document Scanners for PDFs and Paper Notes

A document scanner should help you turn a paper page into a readable file. Compare the capture workflow, page correction, and export choices before deciding which app suits receipts, written notes, or multi-page documents.

OpenScan for a straightforward document library

OpenScan provides a scanning workflow and a library for saved documents. Start a scan, adjust the page edges and save the result with the documents already on your phone. It is a useful starting point for ordinary paper-to-PDF work on Android.

FairScan for automatic page handling

FairScan focuses on detecting the document, correcting its perspective, and enhancing the image before PDF export. The publisher documents on-device processing and no ads. Its capture, review, and save stages give you a short route from a paper page to a shareable file.

OSS Document Scanner for editing and export controls

OSS Document Scanner adds page adjustments and PDF export tools. Review the page boundaries and the preview before sharing a scan. Its documented OCR feature can help when you need recognized text, but recognition results still need checking against the original.

Try the workflow that matches the documents you handle. Inspect small print, page edges, page order, and the exported file before sending it to someone else. A clear capture matters as much as the number of editing controls.
