All processing happens on your device. Your files never leave your phone.

Download

Get the latest APK: PaperKnife v1.1.0

  • Full (GitHub releases): everything, including offline OCR.
  • Lite (IzzyOnDroid): same app without the OCR engine — smaller download.

Get it at IzzyOnDroid

Or use the live site — installable as a PWA for offline access.

Run the web version locally

Requirements: Node.js 22+ and git. Everything below runs on your own machine.

git clone https://github.com/potatameister/PaperKnife.git
cd PaperKnife
npm ci                  # install dependencies (also used by CI)
npm run vendor:ocr      # optional, only needed for Deep OCR (one-time)
npm run dev             # start the local server (http://localhost:3000)

Notes:

  • npm run vendor:ocr is optional — skip it and everything works except Deep OCR. The engine files (~30 MB) are never committed to git, so a fresh clone cannot do OCR until you run it. Re-running later is safe — it skips what is already there.
  • npm run build produces a static dist/ folder you can serve with any static host (npm run preview to check it locally). No server component exists — it is plain files.
  • To build the Android APK yourself, you additionally need JDK 21 + Android SDK, then npx cap sync android after npm run build. The OCR files (if vendored) are bundled into the full APK automatically.
