Free online JWT generator tool to create test tokens for auth and API development.

How it works

JWT Generator builds test tokens from header and payload data to speed up auth integration and staging diagnostics. It supports rapid claim experimentation for frontend and backend validation. Never use production secrets in public or shared environments.

Example

Header:
{"alg":"HS256","typ":"JWT"}

Payload:
{"sub":"123","role":"admin"}

FAQ

Can I use generated JWTs in production?

Use production tokens only from your trusted auth service and key management workflow, not ad-hoc generators.

How should I set exp for testing?

Use short expirations for realistic tests and explicitly test refresh and expiry-edge behavior.
