About JWT

JWT (JSON Web Token) is a compact, URL-safe means of representing claims to be transferred between two parties. The claims in a JWT are encoded as a JSON object that is digitally signed using JSON Web Signature (JWS).

Warning: This decoder only decodes and displays the token content. It does not verify the cryptographic signature. Always verify signatures server-side before trusting any data from a JWT.
