About JWT Decoder
JSON Web Tokens (JWT) are the standard for secure authentication in modern web applications. Our JWT Decoder lets you inspect tokens safely by decoding them entirely in your browser. View the header, payload, and signature in a clean, formatted view. Essential for debugging authentication issues, inspecting token claims, checking expiration times, and understanding token structure. Since all decoding happens client-side, your tokens never leave your device—critical for security and compliance.
