Overview
Scan, OCR, merge, compress and protect PDFs on-device. Files never leave the phone.
The problem
Most PDF tools upload your documents to a server, which is a privacy risk for contracts, IDs and invoices.
The approach
PDF Master does all its processing on the device. Scanning, text recognition, merging, compression and encryption run locally, so the app works offline and files stay private.
What I built
- An on-device OCR and scanning pipeline
- PDF merge, compression and protection tools
- An offline-first Android app on Google Play
