FAQ

What is AES Encrypt?

AES Encrypt password-based AES-GCM/CBC encryption using the Web Crypto API. It runs entirely in your browser, so your data stays private.

Is AES Encrypt free to use?

Yes. AES Encrypt is free, unlimited and works without registration or installation.

Does my data get uploaded?

No. All processing happens locally in your browser; nothing is sent to any server.

Good to know

  • Everything runs client-side, so extremely large inputs are limited by your browser tab’s memory rather than by a server upload limit.
