JWT decoder

Paste a JWT to see its header and payload as formatted JSON, with issue and expiry dates in your time zone and whether it has expired.

Private by design: everything is processed on your device. Nothing you add is uploaded or stored.

How to use it

  1. Paste a token.
  2. Read the decoded parts and dates.

Questions

Is the signature verified?

No. Decoding shows the content only; never trust a token without verifying it on your server.

Is the token sent anywhere?

No. It stays on your device.
