AES Encryption & Decryption

Bank-grade AES-256 encryption in your browser. Secure your messages with a password.

How It Works

The AES Encryption & Decryption runs entirely in your browser using JavaScript. Unlike other tools that send your data to a server, we process everything locally on your device. This guarantees 100% privacy and blazing fast speed.

  • No server interaction – data never leaves your device
  • Instant results since there is no network latency
  • Works offline once the page is loaded
  • Free to use with no usage limits

How to Use

1

Choose Mode

Select "Encrypt" to secure text or "Decrypt" to reveal it.

3

Process

Click the button to perform AES-256-GCM encryption/decryption instantly in your browser.

Frequently Asked Questions

Is my data safe?
Yes. All encryption happens locally in your browser using the native Web Crypto API. Your password and text are never sent to any server.
What algorithm is used?
We use AES-GCM (256-bit key) with PBKDF2 for key derivation (100,000 iterations) and a random salt/IV for every encryption.
Can I recover my password?
No. If you lose the password, the data cannot be decrypted.
