Free Text Encryption/Decryption Online — Encrypt and decrypt text with AES-256
How to Encrypt Text
Enter your text and a password, then click Encrypt. The text is encrypted using AES-256-GCM with PBKDF2 key derivation (100,000 iterations). Share the encrypted output — only someone with the password can decrypt it.
How secure is this?
AES-256-GCM is military-grade encryption used by governments and banks. With a strong password, it's virtually unbreakable. All processing happens in your browser — nothing is sent to any server.
What if I forget the password?
There is no recovery. The encryption is one-way without the password. Always store your password securely.
