What is a JSON Web Token (JWT)?

A JSON Web Token (JWT) is an open standard (RFC 7519) that defines a compact and self-contained way for securely transmitting information between parties as a JSON object. This information can be verified and trusted because it is digitally signed.

Why use our JWT Decoder?

Unlike other tools, OnlineView processes your tokens 100% client-side. Your sensitive authentication data never touches our servers.

Structure of a JWT

A JWT consists of three parts separated by dots: Header, Payload, and Signature. We help you visualize the JSON data hidden inside.
