Use this free JWT Decoder to inspect JSON Web Tokens quickly in the browser. It helps you read JWT header and payload data, check common claims such as exp, iat, iss, aud, sub, and understand what a token contains during API development, authentication debugging, and integration testing. Paste a JWT token to decode it instantly without writing code or manually splitting Base64 URL segments.
