What is a JWT? A Simple Explanation
JWT, or JSON Web Token, is an open standard for securely transmitting information between parties as a JSON object. Think of it as a secure, digital ID card for the web.

- API Tester: Test your endpoints to see if they are issuing the correct JWTs.
- Base64 Converter: Decode the header/payload parts instantly (though our main tool does it automatically).
- JSON Toolkit: Format the JSON payload once it's decoded.
Why Do Developers Need to Decode JWTs?
During development and debugging, it's crucial to inspect the payload of a token to ensure it contains the correct user information and expiry date. A JWT Decoder makes this process instant.
