AES Encryption Tool

Encrypt and decrypt text or files with AES-256

100% client-side. Your password and data never leave your browser.

About AES Encryption Tool

The AES Encryption Tool lets you encrypt or decrypt text and files directly in your browser using AES-256-GCM, the same algorithm used to protect classified government data. Your password is converted into an encryption key with PBKDF2-SHA256 (600,000 iterations), making brute-force attacks impractical. Everything runs locally via the native Web Crypto API — your data never leaves your device.

Frequently Asked Questions

Is my password sent to a server?
No. Encryption and decryption happen entirely in your browser. Your password and your data never leave your device.
What algorithm is used?
AES-256-GCM by default — an authenticated encryption mode that detects tampering. AES-256-CBC is also available. Keys are derived from your password using PBKDF2-SHA256 with 600,000 iterations.
Can I recover my data if I forget the password?
No. Strong encryption has no backdoor. If you lose your password, the encrypted data cannot be recovered. Use a password manager.
