What is a JWT?
A JSON Web Token (JWT) is a compact, URL-safe means of representing claims to be transferred between two parties. The claims in a JWT are encoded as a JSON object that is digitally signed using JSON Web Signature (JWS). JWTs are often used for authentication and authorization in web applications.
How to Use Our JWT Reader?
Simply paste your JWT into the input field, and our tool will automatically decode its header, payload, and signature. This allows you to easily inspect the contents of any JWT without needing to write code or use command-line tools. All decoding is performed client-side, ensuring your token data remains private and secure.
