About this tool
There is no server behind JWT Decrypt. JWT Decrypt decodes a JSON Web Token in your browser, showing the header and payload without verifying secrets remotely.
The token is parsed on your device and never transmitted. No data is sent anywhere, so it stays fast and private by default.
