JWT Decoder
JWT Decoder
Decode JWT token header and payload.
How to Use
Enter a JWT (JSON Web Token) to decode the header and payload, and display the signature separately.
Signature verification is not performed. Everything runs offline and nothing is sent to the server.
💡
An invalid JWT will result in an error. Use a dedicated tool if verification is required.
Typically targets tokens in the "xxxxx.yyyyy.zzzzz" three-part format.
