About JWT Decoder
Decode any JSON Web Token (JWT) to inspect its header and payload claims without needing a secret. Useful for debugging authentication issues, verifying token contents, and understanding JWT structure during development.
Key features
- Decodes header and payload of any JWT
- Shows all claims including exp, iat, and custom claims
- Highlights token expiration status
- Formats JSON payload for readability
- Fully client-side — tokens never leave your browser
How to use JWT Decoder
- 1Paste your JWT token (the full Bearer token string) into the input
- 2The header and payload are decoded and displayed automatically
- 3Review the claims including expiration time and user data
- 4Check the signature section to understand the algorithm used
Frequently asked questions
- Is it safe to paste my JWT token here?
- JWT decoding is safe in this tool because everything runs in your browser. However, treat tokens like passwords — do not paste production tokens containing sensitive user data into public tools.
- Can this tool verify JWT signatures?
- JWT signature verification requires the secret key. This tool decodes the header and payload without verification — useful for inspecting content, not for security validation.
- What is a JWT token?
- A JSON Web Token (JWT) is a compact, URL-safe token format consisting of three Base64-encoded parts: header (algorithm), payload (claims), and signature. Widely used for authentication.
- Why does my JWT show "expired"?
- The "exp" claim contains a Unix timestamp. If the current time is past that timestamp, the token is expired. Use the Timestamp Converter to convert the value to a readable date.
