JWT Decoder is a free online developer tool to decode a JSON Web Token (JWT) instantly to view the claims inside, such as the algorithm used to sign it and the attached data.

Enter a JSON Web Token you would like to decode in the input field and then click the decode button. The result will be split into header and payload in the JSON format accordingly.

The header consists of the algorithm used to encode the signature, such as HS256 which means the token uses HMAC-SHA256 to generate the signature and the token type; for instance JWT.

The payload contains a set of claims as known as data in a token. One of the standard claims is iat which stands for Issued At. It's a UNIX timestamp referring to the creation date and time of the token.

Once a JSON Web Token is decoded, you can copy the result to your clipboard using the copy button.
