Free AES Text Encryption Tool — Encrypt & Decrypt Messages Online
Encrypt any message with AES-GCM directly in your browser. Share the encrypted URL — only someone with the password can decrypt it. Zero server involvement.
Features
AES-GCM Encryption
Uses the Web Crypto API with AES-256-GCM — the same standard used in modern secure messaging apps.
Shareable Encrypted URLs
The encrypted ciphertext is embedded in the URL so you can share it as a link.
Zero Knowledge
Encryption and decryption happen entirely in the browser. The server never sees your plaintext or your password.
How It Works
Enter the text you want to encrypt.
Choose a passphrase. The recipient will need this to decrypt.
Click encrypt to generate a ciphertext URL.
Send the URL to your recipient along with the password (via a separate channel).
