FAQ

What is a JWT?

A JSON Web Token (JWT) is a compact, URL-safe way to represent claims between two parties. It consists of three Base64URL-encoded parts: header, payload, and signature.

Does this tool verify the JWT signature?

No, this tool only decodes the JWT to show its contents. It does not verify the cryptographic signature. Never trust a JWT without server-side verification.

Is my token safe?

Yes, all decoding happens in your browser. No data is sent to any server. However, be cautious about sharing decoded token contents.
