Frequently Asked Questions

What is a JSON Web Token (JWT)?

JSON Web Token (JWT) is an open standard (RFC 7519) that defines a compact and self-contained way for securely transmitting information between parties as a JSON object.

Can this tool modify or sign JWT tokens?

This tool is currently designed exclusively to inspect and decode JSON Web Tokens client-side. It parses the base64url encoded header and payload segments.

Is my secret key or token uploaded to any server?

No. Decoding is performed entirely in your browser using pure JavaScript. Your token, claims, and data never leave your local machine.
