This tool only decodes JWT. It does NOT verify signature and does NOT guarantee token authenticity.

No common claims found.
JWT contains three dot-separated parts: header, payload, and signature. This page separates those parts and formats the first two into readable JSON.
It is useful for API troubleshooting, auth testing, and integration checks when you need to inspect token content fast.
Many JWT claims store timestamps in Unix format. We convert those values to local and UTC date strings so you can validate timing quickly.
We also highlight common claims such as iss, aud, sub, and role to improve manual verification during debugging.
Decoding is not signature verification. A decoded JWT is not automatically trustworthy. Always verify signatures in your backend or trusted environment.
Processing runs locally in your browser by default, which helps privacy during quick token inspection.
No. It only decodes and displays token parts. Signature verification must be done elsewhere.
Yes. If exp is present, the tool shows readable date and expiration status.
No by default. Decoding runs in your browser.
