FAQ

Base64 Encoder / Decoder questions

Does this Base64 tool upload my input?

No. Encoding and decoding run locally in your browser, and the tool does not send your input to a server.

Is Base64 encryption?

No. Base64 is an encoding format, not encryption. Anyone can decode Base64 text unless it is encrypted separately.

Can Base64 handle Unicode text?

Yes. This tool uses UTF-8 encoding, so it can encode and decode ordinary Unicode text.
