JWT Decoder
JSON Web Tokens (JWT) are a compact, URL-safe means of representing claims to be transferred between two parties. JWTs are commonly used for authentication and authorization in modern web applications. This free online tool decodes JWT tokens to reveal their header and payload contents. You can view the algorithm used, expiration time, and any custom claims. All processing happens locally in your browser - your tokens never leave your device.
