The icon read-only property of the Notification interface contains the URL of an icon to be displayed as part of the notification, as specified in the icon option of the Notification() constructor.

Note: This feature is available in Web Workers.


var icon = Notification.icon;


A USVString.


In our Emogotchi demo (see source code), we run a simple spawnNotification() function when we want to fire a notification — this is passed arguments to specify the body, icon and title we want, then it creates the necessary options object and fires the notification using the Notification() constructor.

function spawnNotification(theBody,theIcon,theTitle) {
  var options = {
      body: theBody,
      icon: theIcon
  var n = new Notification(theTitle,options);
