Ideal for developers, testers, and security professionals, our JWT Decoder/Encoder tool provides a user-friendly interface to work with JWT tokens efficiently. Use it to troubleshoot authentication issues, validate token data, and enhance security in your web applications.

What is JWT Token Decoder/Encoder?

This tool allows you to both decode and encode JWT tokens. You can inspect the contents of existing tokens or create new ones by providing custom header and payload data.

How to Use This Tool

To Decode:

  1. Switch to the "Decode" tab
  2. Paste your JWT token into the input field
  3. Click "Decode Token"
  4. View the decoded header and payload information

To Encode:

  1. Switch to the "Encode" tab
  2. Enter your header and payload JSON
  3. Click "Encode Token"
  4. Copy the generated token

Note: The encoder creates tokens with a dummy signature. In a production environment, tokens should be properly signed with a secret key for security.
