Overview
What is JWT Decoder?
A JWT Decoder allows you to see exactly what data is encoded within a token without needing the secret key. It breaks the token into its three constituent parts: the Header (algorithm and type), the Payload (claims and data), and the Signature. Our tool is privacy-focused, performing all decoding locally in your browser.
