JWT (JSON Web Token) is a compact, URL-safe token format used for authentication and information exchange. It contains a header, payload, and signature.

Is it safe to decode JWTs here?

Yes. Decoding happens entirely in your browser. No tokens are sent to any server. Note: decoding only reads the token — it does not verify the signature.

Can this tool verify JWT signatures?

This tool decodes and displays the token contents. Signature verification requires the secret key, which should not be entered into any online tool.
