Base64 Encode & Decode — Unicode-Safe, Local

Convert text to and from standard Base64 (RFC 4648) with correct UTF-8 handling — emoji, Cyrillic, and CJK characters encode and decode losslessly, which many naive formatters get wrong.

Everything runs in your browser, so tokens and encoded credentials are never transmitted.
