- Header — algorithm and token type

FAQ
Does this validate the signature?No — signature validation requires the secret key, which should never be shared client-side.
Is it safe to paste my JWT here?Yes — for this decoder, decoding runs in your browser; your token is not sent to our servers.
What about expired tokens?The tool shows the expiration timestamp and whether the token is currently expired.
