About this tool

Paste a JSON Web Token. The decoder shows the header and the payload, and turns the iat, nbf and exp time stamps into readable dates. It does not check the signature. The token stays in your browser, but avoid pasting live production tokens anywhere you do not trust.

Frequently asked questions

Does it verify the signature?

No. It only decodes the content. Verifying needs the secret or public key.

Is a JWT encrypted?

A normal JWT is only encoded, not encrypted, so anyone with the token can read it. Do not put secrets in it.
