Decode JSON Web Tokens

Decodes JSON Web Tokens (JWT) to reveal their underlying structural components. Users input an encoded JWT string, which the tool then parses into its three distinct parts: the header, the payload, and the signature. It deciphers Base64-encoded data for each segment, allowing users to view the original claims and metadata embedded within the token structure. This process helps reveal exactly what information a service or application has packaged and signed using the JWT standard. Developers, security researchers, and web developers utilize this tool when they need to inspect or validate an existing JSON Web Token without access to the originating server's private keys. It provides a quick way to examine claims such as user IDs, expiration dates, and roles that are typically contained within the payload.
