What is a JSON Web Token (JWT)? JWTs are the modern standard for API authentication. They allow stateless communication of user sessions and scopes. However, debugging them means you have to convert their encoded Base64 format back into a readable JSON string.
100% Local Decoding Pasting API credentials into online tools can be dangerous! The DevCanvas JWT Decoder is built with privacy-first architecture. It leverages the browser's native Javascript engine to Base64 decode your token's Header and Payload directly in your local memory.
Your tokens are **never** transmitted to our servers or saved anywhere else, ensuring full enterprise security compliance.
