Encoders & Decoders_

Encoders and decoders handle the wrapping formats data travels in: Base64 for binary-safe transport, percent-encoding for URLs, and JWTs for signed claims. The tools in this category are strict where strictness protects you — invalid Base64 bytes are flagged rather than silently mangled, URL decoding tolerates real-world sloppiness but tells you about it, and the JWT decoder reads headers and claims without ever sending your token anywhere, which matters because a pasted token is a credential. Everything runs client-side; nothing you decode is seen by a server.
