Offline image transfer

Send images through animated QR without Wi‑Fi, Bluetooth, or pairing.

Upload a photo on one device, display the sender screen, and reconstruct it on another device through the camera. This works entirely offline and supports images up to 4 MB.

How it works

One device uploads a photo, streams it as a fountain-coded QR animation, and the other device scans it in real time. Frames can be dropped and still recover the full image.
