Unlike other online converters, **Base64 Pro** processes everything in your browser. Your sensitive data (images, documents, credentials) is never sent to our servers, ensuring complete privacy.

Tip: If your Base64 string is very large (e.g., >20MB), pasting it might freeze your browser momentarily. This is normal for large text operations in the browser.
