About this JWT decoder
A JSON Web Token is three Base64URL segments — header, payload, signature — joined by dots. This tool decodes the header and payload so you can inspect the algorithm, claims, and expiry (exp, iat, nbf are also shown as readable dates). A leading Bearer prefix is stripped automatically.
Decoding happens entirely in your browser, which is exactly how you want to inspect production tokens: the token never leaves this tab. Note that decoding is not verification — this tool does not check the signature.
