Key Features

Confidential delivery

Send encrypted images over any app. The image looks like noise to everyone except the intended recipient who has the key.

Use with your friends

Agree on a password with your friends face-to-face. Then, share pictures with each other without worrying about leaks.

Zero Server Dependency

Everything happens on your device. No upload to third-party servers. No accounts, no backdoors.

User Notes

Avoid recompression: Always send the original encypted image. Encrypted images that have been compressed by communication app or social media cannot be decrypted.

Password Security: Use strong, unique passwords. If the password is lost encrypted images cannot be recovered.

Frequently Asked Questions

How secure is the encryption?

Cipher Vision uses military-grade encryption with PBKDF2 key derivation, 256-bit salts, and multi-layer visual scrambling. The steganographic approach hides metadata within image pixels, making detection extremely difficult.

Are my images uploaded to a server?

No. All processing happens locally in your browser using WebCrypto APIs. Your images never leave your device, ensuring complete privacy and security.

What happens if I forget my password?

Passwords cannot be recovered due to the cryptographic design. Always use memorable passwords and consider keeping secure backups of your passwords.

What image formats are supported?

Input: PNG, JPG, WebP, and most common image formats. Output: PNG format to preserve encryption data integrity and prevent compression artifacts.

Can encrypted images be detected?

The steganographic approach makes encrypted images appear as normal images to casual observation. However, sophisticated analysis might detect the presence of hidden data.
