How it works
- Paste a JWT token.
- Decode the header and payload.
- Review claims such as exp, iat, iss, aud and scopes.
Token inspection
JWT decoder
Paste a JWT and inspect the readable header and payload claims without sending the token to an Orbitautil server.

The processed output appears here after you run the tool.
Generated output
Decode, not verify
JWT header and payload are Base64URL-encoded and readable. Signature verification requires the correct key and is outside this browser utility.
Handle tokens carefully
Tokens can act like credentials. Prefer test tokens and avoid sharing decoded values in screenshots or tickets.
Useful claims
Look at exp for expiration, iss for issuer, aud for audience and scope or roles for authorization context.
Common use cases
- Debug authentication during API integration.
- Check token expiration while developing.
- Inspect claims from test tokens.
Limitations
- This tool does not validate the signature.
- Do not paste production secrets unless you understand the risk.
- Encrypted or non-JWT tokens are not decoded.
Frequently asked questions
Does this validate the JWT signature?
No. It only decodes the visible header and payload.
Is the JWT uploaded?
No. Decoding runs in your browser.
Can I use a real production token?
Prefer test tokens. Real tokens should be treated as credentials.
