About Text Encryption

Encrypt and decrypt text using AES and other algorithms.

Text Encryption is a free tool in the Security Tools category on BrowseryTools. It runs entirely in your browser: what you give it is processed on your own device and is never uploaded to a server, there's no registration, no ads and no watermarks, and it keeps working with no connection once the page has loaded.
