Decode JWT headers and payloads locally. Inspect claims without sending tokens to a server. Signature verification is not included.

How to inspect JWT claims

  3. Review the claims and copy or download the JSON.

Example

Inspect the exp, iss or aud claim while debugging token creation.

Supported options and limitations

Decoding does not verify a signature, expiration or permissions. Never treat decoded claims as trusted authentication evidence.
