About this tool
No secret needed
A JWT is only Base64Url-encoded for transport, so anyone can decode and read its contents without the secret key.
Completely private
All decoding happens 100% in your browser. The token is never sent to our servers.
Token verification
This tool focuses on inspecting the data. To verify validity you need the secret key.
