Decode a JWT header and payload in your browser and inspect JSON claims without sending the token to a server.

Decoding does not verify the signature, issuer, audience or expiration. Do not treat decoded claims as authenticated. Encrypted JWE is unsupported.

Up to 100,000 UTF-16 units per input and 1,000,000 per result. See the supported formats and examples below.
