Encrypt

Your message is encrypted with AES-256-GCM using a key only you control. Even if the image is analyzed, the contents remain unreadable.

Embed intelligently

Chlamys analyzes the image and places the encrypted data only in areas where changes are virtually invisible to the human eye.

Zero knowledge

Everything happens in your browser. Your photos and messages never leave your device. No accounts. No servers.

Concealed images look completely ordinary. Only someone with the key can reveal what’s inside.
