Free, runs entirely in your browser — no sign-up, no file upload to a server.
What does JWT Generator do?
It creates and signs a JSON Web Token (JWT) from a custom header and payload you provide.
How do I use it?
Enter your payload fields and a signing secret, and a signed JWT is generated instantly.
Is my input sent anywhere?
Everything runs in your browser — nothing you type or paste is sent to a server.
Is this safe to use with real tokens/secrets?
The decoding/signing happens entirely in your browser, so a token or secret you paste in is never sent to a server — but as a general precaution, avoid pasting production secrets into any third-party tool when you can test with a dummy value instead.
