About this tool
Decode a JSON Web Token to see its header and claims, with human-readable expiry. Nothing is sent anywhere.
Nothing is uploaded. This page makes no network requests with your data, and its Content-Security-Policy forbids them.
This tool is built from Sandbox blocks. Use “Take it apart” to change how it works.
