What is a JWT?

JSON Web Token (JWT) is an open standard (RFC 7519) that defines a compact and self-contained way for securely transmitting information between parties as a JSON object.

How to use this tool?

Simply paste your token into the text area. The tool will automatically split it into three parts (Header, Payload, Signature) and decode the Base64Url encoded strings. We highlight the expiration date (exp) if present.
