JWT Decoder - Decode JSON Web Tokens

What is a JWT Decoder?

A JWT (JSON Web Token) Decoder parses dot-separated Base64UrlEncoded JWT tokens into readable JSON objects. A standard JWT consists of three parts: a **Header** (specifying signing algorithm), a **Payload** (containing user claims and expiration timestamps), and a **Signature**.

How to Use the JWT Decoder

1. Paste Token: Enter an encoded JWT string into the full-width input box.
2. Decode Token: Click "Decode JWT Token" to inspect token claims, issuance (`iat`), and expiration (`exp`) dates.
3. Copy Claims: Copy payload data directly to your clipboard.
