FAQ

Does this JWT Decoder verify the token signature?

No. It decodes header and payload for inspection, but signature verification must be done on your server.

Is my JWT uploaded anywhere?

No. JWT decoding happens locally in your browser and is not sent to UtilityCove servers.

Can I inspect exp, iat, and nbf claims?

Yes. The tool parses standard time claims and shows readable date values when present.
