JWT Decoder

Free JWT Decoder – Decode & Verify JSON Web Tokens Online

The JWT Decoder tool on ToolsInbox helps developers and security professionals easily decode, verify, and analyze JSON Web Tokens directly in the browser. A JSON Web Token (JWT) is a compact, URL-safe way to represent claims between two parties and is widely used in authentication, authorization, and secure data transmission.

What is a JWT?

A JWT (JSON Web Token) is a string consisting of three parts separated by dots: the header, payload, and signature. These tokens are used to securely transmit information, often in authentication and API authorization systems.

• Header: Contains information about the token type and algorithm.
• Payload: Stores user data or claims.
• Signature: Ensures token integrity and prevents tampering.
