How it works
The page converts text to bytes before Base64 operations, avoiding broken non-ASCII characters.
Input stays in the browser. The static page can be deployed independently while its canonical SEO URL stays under the tool-group subdomain.
Encode and decode Base64.
Convert Unicode text to Base64 and decode Base64 back to text locally in your browser.
