Base64 Encode & Decode

Encode UTF-8 text as Base64 or decode Base64 back to Unicode text.

Decode accepts optional padding and ignores spaces, tabs, and line breaks. The decoded bytes must be UTF-8 text. Base64 is an encoding, not encryption.

Use URL-safe Base64 (- and _ instead of + and /)

URL-safe encoding omits padding. Decoding uses the selected alphabet.
