FAQ

Is Base64 encryption?

No. It is an encoding anyone can reverse, so it does not protect passwords or other secrets.

Does it handle Japanese text?

Yes. Text is treated as UTF-8, so Japanese and emoji encode and decode correctly.

Why do I see "Invalid Base64"?

It appears when the input contains characters that are not valid Base64, or when the decoded bytes are not valid UTF-8 text.
