Frequently asked questions

Does Base64 encrypt data?

No. Base64 is an encoding and can be reversed. Never use it as a security boundary.

Does it handle emoji?

Yes. Text conversion uses UTF-8 bytes before Base64 or hex encoding.

Why does URL decoding fail?

The input may contain malformed percent escapes or may use a different encoding.
