JWT Decoder
Decode and inspect JSON Web Tokens instantly.
Paste a JWT token to decode its header and payload. All processing happens locally in your browser.
Features
Our JWT Decoder provides a quick and easy way to decode and inspect JSON Web Tokens. JWTs are commonly used for authentication and authorization in web applications, and being able to quickly inspect their contents is essential for debugging.
Simply paste your JWT token to instantly view the decoded header (algorithm and type), payload (all claims including expiration and issued-at times), and the encoded signature. Expiration times are highlighted to show whether the token is still valid or has expired.
Note: This is a decoder only, not a verifier. It does not validate the signature against a secret key. All processing happens locally in your browser - your tokens are never sent to any server.
