Why Use HTML Encoding/Decoding?
HTML encoding converts special characters (<, >, &, ", ') into entities (<, >, &, ", ') to prevent XSS attacks and display code safely. Decoding reverses this for readability. A combined tool lets you encode user input for security, then decode API responses—all in one place.
