What is AES Encryption?
AES (Advanced Encryption Standard) is a symmetric encryption algorithm adopted by the U.S. government and used worldwide for securing sensitive data. It's considered one of the most secure encryption methods available today.
Our tool uses AES-GCM (Galois/Counter Mode), which provides both encryption and authentication, ensuring your data is not only encrypted but also protected against tampering.
Why Use AES-GCM?
- •Military-grade security: Used by governments and enterprises worldwide
- •Authenticated encryption: Detects if encrypted data has been tampered with
- •Fast performance: Optimized for modern processors
- •Industry standard: Widely supported and thoroughly tested

Keep backups of encrypted data and passwords in separate secure locations
Frequently Asked Questions
Is my data sent to any server?
No. All encryption and decryption happens entirely in your browser using the Web Crypto API. No data is ever transmitted to our servers.
How secure is AES-GCM encryption?
AES-GCM is military-grade encryption used by governments worldwide. With a strong password, it's virtually impossible to break.
What if I forget my password?
Unfortunately, encrypted data cannot be recovered without the correct password. This is by design to ensure maximum security.
Can I encrypt large files?
Yes, the tool supports encrypting large text files. However, very large files may take longer to process depending on your device.
What's the difference between Base64, Hex, and JSON formats?
Base64 is compact and URL-safe, Hex is human-readable, and JSON includes all metadata in a structured format for easy storage and sharing.
Can I use this for commercial purposes?
Yes, this tool is completely free to use for personal and commercial purposes.
