It's built for developers who need a data URI for CSS or HTML, anyone decoding a token, or someone who just needs a quick, clean Base64 encode or decode without hunting through a cluttered web tool. Type or paste on either side and watch the other update instantly — encoding and decoding share one screen, so there's no mode to pick first.
