Technical Specifications & How It Works
HTML requires characters like <, >, &, and quotes to be escaped as entities when rendering literal text to prevent code injection and parsing errors.
Decoding replaces named entities like " and numeric codes like / with their original characters for easy reading.
All operations run client-side in your device's browser, preventing private code or configuration data from being exposed.
