Base64 Encode / Decode

Text ⇄ Base64

Base64 is how binary-unsafe text gets carried through places that only accept plain ASCII: HTTP headers, basic auth strings, data URIs, and the segments of a JWT. Encoding and decoding it is a constant small task in debugging, and the strings involved often contain credentials. This converter runs both directions in the page with proper Unicode handling, so accented characters and emoji survive the round trip intact.
