About JWT Tokens
JSON Web Tokens (JWT) are a compact, URL-safe means of representing claims to be transferred between two parties. JWTs are commonly used for authentication and information exchange in web applications.
Key Benefits:
- Compact and self-contained for efficient transmission
- Digitally signed for integrity verification
- Stateless authentication without server-side storage
- Cross-platform compatibility and wide industry adoption
Our JWT decoder uses standard Base64 decoding to safely parse token contents locally in your browser, ensuring your sensitive data never leaves your device.
