Decode Base64 to text
Decode Base64 strings back to plain text, entirely offline.
What to know
Decoding handles standard Base64. Whitespace is trimmed automatically, which matters because copied strings often carry stray line breaks.
The result is interpreted as UTF-8 text. Decoding a Base64-encoded image or other binary file will produce unreadable characters rather than the file itself.
Questions
Is anything uploaded to a server?
No. Every tool on this site runs inside your browser using standard web APIs. There is no upload, no account, no logging and no server holding your data afterwards. You can confirm it by opening your browser's developer tools and watching the network tab stay empty while you work.
