About this Base64 encoder/decoder
Encoding is UTF-8 safe, so emoji and non-Latin text round-trip correctly. Decoding accepts both standard and URL-safe alphabets and tolerates missing padding. The URL-safe option produces - and _ instead of + and /, with padding stripped — the alphabet used in JWTs and URL parameters.
Conversion happens in your browser via the native btoa/atob functions — credentials and tokens you paste stay on your machine.
