ZeroLeak: Invisible Watermarks

ZeroLeak helps you protect private images before you share them. It uses invisible watermarking to link each shared image to a specific recipient, without changing how the image looks.

When you share an image, ZeroLeak embeds a unique, undetectable pattern directly into the file. If that image ever appears somewhere it shouldn’t, you can scan it with ZeroLeak to instantly identify who originally received that copy.

Everything runs entirely on your device. Your images never leave your phone, no accounts are required, and no cloud or servers are involved. ZeroLeak works offline and preserves full image quality.

Designed for privacy, simplicity, and control, ZeroLeak gives you confidence when sharing sensitive photos and helps you stay protected if a leak ever happens.

Protect your images. Detect leaks. Stay private.
