Paste a JSON Web Token to instantly inspect its header, payload, and claims — with human-readable timestamps and an at-a-glance expiry status. Everything runs entirely in your browser; your token is never sent anywhere.
Signature is NOT verified. This tool decodes only — it does not check the token's signature or validate it against a key. Decoding happens entirely in your browser, and the token is never uploaded or sent to any server.
A JWT has three dot-separated parts: header.payload.signature.
| Claim | Value | Meaning |
