ShareByLight File Transfer

Transfer files between air gapped devices without a physical connection, just by camera.

ShareByLight moves files from one device to another using only the screen and camera.

What it’s for • Pass a file when you don’t want (or can’t use) Wi-Fi or Bluetooth, between air gapped devices • Share between iPhone, iPad, and Mac without a network • Keep the transfer offline and local to the devices in front of you

How it works

1. On one device, choose a file and start the stream
2. On the other device, open Receive and point the camera at the screen
3. When the transfer finishes, save the file

Features • Send and receive on the same app • Works across iPhone, iPad, and Mac • Optional password protection for the file • Clear progress while the transfer runs • Free: one direction and small files • Pro: both directions and larger files

Tips for a smooth transfer • Max brightness on the sending screen • Hold steady and fill the frame • Reduce glare and strong backlight

No account required. No cloud. Data moves as light between the devices you choose.
