FAQ

Why does Base64 decoding fail?

The input may contain invalid characters, missing padding, or it may represent binary data rather than UTF-8 text.

Can Base64 represent binary data?

Yes. Base64 often encodes binary data. This tool attempts to decode as UTF-8 text.

Is my data uploaded?

No. Decoding runs locally in your browser.
