JWT Decoder
Decode JWT headers and payloads in your browser. No verification, no uploads—just quick inspection.
Chain this with other tools →NewHow it works
JWTs consist of three Base64URL-encoded parts separated by dots: header, payload, and signature. This tool splits the token, decodes the Base64URL-encoded header and payload using atob(), and displays the JSON contents. No signature verification is performed.
Common Use Cases
- Inspecting JWT claims like expiration time (exp) and issued at (iat)
- Debugging authentication issues by checking token contents
- Verifying user roles or permissions stored in JWT payload
- Understanding JWT structure for API development
Frequently Asked Questions
Can this tool verify JWT signatures?
No. This tool only decodes and displays JWT contents. Signature verification requires the secret key or public key, which should never be exposed to client-side tools.
Is it safe to paste my JWT here?
Yes. All processing happens in your browser. No data is sent to any server. However, never share your tokens publicly as they may contain sensitive information.
