JWT Decoder
JWT Decoder tool is free online tool that allows you to analyze and understand the contents of a JSON Web Token (JWT).
JWT decoder serve as invaluable companions for developers working with JSON Web Tokens. This browser-based utility allow you to quickly paste and decode any JWT, instantly breaking down its three core components - header, payload, and signature - into readable JSON format. By revealing the token's contents at a glance, it helps troubleshoot authentication issues, verify token claims, and validate token structures during development.
Here's what a JWT Decoder tool does:
-
Takes a JWT as input: You typically paste the JWT string into the tool.
-
Decodes the JWT: It breaks down the JWT into its three parts:
-
Header: Contains information about the token, like the algorithm used to sign it.
-
Payload: Holds the actual data or claims about the subject of the token.
-
Signature: Verifies the authenticity and integrity of the token.
-

-
Understanding token structure: If you're new to JWTs, a decoder helps you understand how they work and what information they carry.
-
Testing and development: Decoders can be helpful in development to ensure your application is generating and verifying JWTs correctly.
