About the JWT Decoder
This tool helps you quickly decode and inspect the contents of a JSON Web Token (JWT). JWTs are commonly used for authentication and authorization in web applications. They consist of three parts: a header, a payload, and a signature, separated by dots. Our decoder allows you to see the header and payload data in a human-readable format.
How it Works
- Paste Token: Simply paste your JWT into the input field.
- Instant Decode: The tool automatically decodes the Base64Url-encoded header and payload and displays them as formatted JSON objects.
- No Validation: Please note that this tool does not validate the token's signature. It only decodes the data for inspection.
