Our Mission
JWT Toolbox was created to provide developers and security professionals with a simple, secure, and user-friendly way to work with JSON Web Tokens (JWTs). We believe that security tools should be accessible to everyone, and that's why JWT Toolbox is completely free to use.
Privacy & Security
At JWT Toolbox, we take privacy extremely seriously. Unlike some online tools, all of our JWT processing happens right in your browser. Your tokens, keys, and data never leave your device. This means:
- No server processing of your sensitive data
- No storage of your tokens or keys
- No tracking of your usage patterns
- The ability to use the tool offline after initial page load
Our Tools
JWT Toolbox offers a comprehensive set of tools to help you work with JWTs:
- JWT Decoder: Easily decode and inspect the header, payload, and signature of any JWT token
- JWT Verifier: Verify the integrity of JWT tokens using your secret key
- JWT Generator: Create new JWT tokens with customizable payloads and signing algorithms
How It Works
JWT Toolbox uses modern web technologies to perform all cryptographic operations directly in your browser:
- Base64 decoding to extract JWT components
- JSON parsing to display header and payload data
- Cryptographic libraries for signature verification and generation
All of this happens locally, providing both security and a fast user experience.
Thank you for using JWT Toolbox!
