About File Encryption

This tool provides secure AES-256-GCM encryption for your files. AES (Advanced Encryption Standard) with GCM (Galois/Counter Mode) provides both confidentiality and authenticity, ensuring your files cannot be tampered with.

Key Features:

How It Works:

Encryption: Select your file, enter a strong password, and click Encrypt. The tool generates a secure .enc file that can only be decrypted with your password.

Decryption: Select the .enc file, enter the same password used during encryption, and click Decrypt to restore your original file.

⚠️ Important: Remember your password! There is no way to recover your files if you forget the encryption password. Consider using a password manager.

🔒 Privacy Guarantee: Your files never leave your browser. All encryption and decryption happens locally using the Web Crypto API. We cannot access your files or passwords.
