Your files never leave your device

Scanning with a phone usually means a cloud round-trip and an app that keeps your pages. Bindery shows a QR code whose link carries a one-time key; the phone opens it in its browser, photographs each page, finds the paper and straightens it, encrypts the image with that key and sends it straight to your computer over a WebRTC data channel. Bindery’s servers relay only the connection handshake.

Pages appear on the computer as they arrive; make a PDF, then run OCR to make it searchable. Both devices should be on the same network; a public STUN server can be switched on to help across networks (addresses only — pages still travel directly). Bindery runs entirely in your browser — your file is never uploaded, so there is nothing to delete from a server afterwards.

How it works

  1. Open Scan from phone on your computer and point the phone camera at the QR code
  2. Capture each page on the phone — it is straightened and sent immediately
  3. Make a PDF on the computer, then OCR it if you want searchable text

Questions people ask

Does the phone need an app?

No. The scan page runs in the phone’s browser; the camera is used through the standard web camera API.

Where do the photos go?

From the phone straight to the computer that showed the QR code, encrypted with the key from the code. They are not uploaded anywhere.

Why must both devices be on the same network?

A direct connection needs a route between them. Turning on STUN exchanges public addresses through a Google STUN server so devices on different networks can usually connect; pages still travel directly.
