FAQ
›Does this tool verify the JWT signature?
No. This tool decodes and displays the header and payload claims client-side without signature verification.
›Is it safe to paste sensitive tokens here?
Yes! Decoding runs 100% locally in your browser using base64url decoding. Your token is never uploaded or sent anywhere.
›What claims are highlighted?
Common claims like exp (expiration time), iat (issued at), nbf (not before), sub (subject), and iss (issuer) are formatted into readable date-times and status indicators.
