Encrypt and decrypt text right in your browser with our free online encryption tool. Choose from AES-128-GCM, AES-256-GCM, AES-128-CBC, and AES-256-CBC algorithms, set your password, and securely transform your text. All encryption and decryption happens locally using PBKDF2 key derivation — your text and password never leave your device.
Shortcut: Ctrl+Enter to process
Uses Web Crypto API for encryption, supporting AES-128/256-GCM/CBC algorithms. All operations are performed locally in your browser, data is never uploaded. Please keep your password safe, as it cannot be recovered.
