Privacy-first Base64 conversion
Why Decode Base64 keeps text and small files in the browser instead of sending them to a server.
Local work is the default
Base64 tools are often used with tokens, JSON payloads, webhook examples, and snippets copied from support tickets. Those values may not be secrets in the cryptographic sense, but they still do not belong in an unknown database. Decode Base64 runs the conversion in the browser, so normal text work stays on the device that opened the page.
Encoding is not hiding
The interface repeats a simple reminder: Base64 is encoding, not encryption. That wording matters because people sometimes paste encoded values into tickets or chat rooms as if the value were protected. The tool helps you inspect and convert data while keeping that security boundary clear.
Useful without an account
There is no login, upload queue, or server-side project history. The page loads as static files, performs the conversion, and leaves. That keeps the workflow quick for developers and safer for people who only need a one-off check.
