1Introduction
JWT (JSON Web Token) is a token format commonly used for authentication, consisting of Header, Payload, and Signature. This tool helps you parse JWT, view the claims it contains, and facilitate debugging and verification. Simply paste the JWT string, and the tool will automatically split and decode the Header and Payload, displaying them in readable JSON format. Note that the Signature cannot be decoded into readable content, but its original value will be shown.

3FAQ
Can the Signature of a JWT be decoded?
Signature is a signature generated using a secret key, used to verify integrity, and cannot be decoded to reveal the original content. This tool mainly displays the Header and Payload.
Is parsing JWT secure?
This tool runs locally in your browser and does not upload your data. Please use it with confidence.
