Frequently Asked Questions
What is a JWT (JSON Web Token)?
A JWT is a compact, self-contained security token used to transmit information between parties as a JSON object. It is commonly used for authentication and information exchange.
Is it safe to decode my JWT here?
Yes, absolutely. Our decoder works completely in your browser. The token is never sent to external servers or saved. All decoding happens locally on your device.
Does this tool verify the JWT signature?
No, this tool only decodes the JWT content (header and payload). It does not verify the cryptographic signature of the token, which requires the secret key or public key used to sign it.
Can I use this tool to create JWTs?
No, this is a decoding tool. It does not generate or sign JWTs. It is designed to read and analyze existing tokens.
