About Text Encryption
Encrypt and decrypt text using AES-256-GCM via the Web Crypto API. Your data never leaves the browser. Use a passphrase or generate a random key.
Text Encryption is a free tool in the Security Tools category on BrowseryTools. It runs entirely in your browser — your data is never uploaded to a server, and there's no registration, no ads, and no watermarks, so your privacy is fully preserved.
