What is a JWT?

A JSON Web Token (JWT) is a compact token used to carry information between systems. It usually contains a header, payload and signature separated by dots.

What is this tool used for?

Display a token header and payload in readable form
Inspect claims such as user ID, role or expiry time
Understand the token structure

Examples

“Use example” fills the matching fields. Then run the tool action.

Example token

Contains harmless demonstration data. The signature is intentionally not valid.

eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiJwbHVzMjMtdGVzdCIsInJvbGUiOiJkZW1vIiwiaWF0IjoxNzAwMDAwMDAwfQ.2rHhQ3DUMMY_SIGNATURE_FOR_DEMO_ONLY

Result

The header and payload are decoded and displayed as JSON. Decoding does not verify the signature and therefore does not prove that the token is authentic.

Security

Do not paste real session tokens, access tokens or confidential production data into public tools.
