Browser Encryption Platform
Encrypt data locally in your browser - No account or software installation required - Integrated password generation and security tools
01
Encrypti0n performs encryption and decryption locally using modern browser cryptography, helping keep your plaintext on your device.
02
Protect text, files, PDFs, images, videos, archives, and other file types using AES-256-GCM encryption with Argon2id password protection.
03
Built-in tools include a secure password generator, password strength analysis, encrypted data inspection, and optional encrypted application data protection.
Local first
Encrypt before data leaves your device
