Frequently Asked Questions
What is a JWT?
A JSON Web Token (JWT) is a compact, URL-safe token format for exchanging claims between parties. It consists of three parts: Header, Payload, and Signature.
Is it safe to decode JWTs here?
Yes. Decoding only reads the Base64-encoded parts. The token is never sent to any server.
Can I verify JWT signatures here?
This tool decodes but does not verify signatures. Signature verification requires the secret key.
