FAQ

Does this tool verify the JWT signature?

No. This tool only decodes the header and payload parts of the JWT (which are base64url-encoded). It does not verify the cryptographic signature. Never trust a JWT based solely on its decoded content.

Is my token safe?

Yes. The decoding happens entirely in your browser. No token data is sent to any server.
