This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.

The Window.URL property returns an object that provides static methods used for creating and managing object URLs. It can also be called as a constructor to construct URL objects.

Note: This feature is available in Web Workers.


Calling a static method:

img.src = URL.createObjectURL(blob);

Constructing a new object:

var url = new URL("../cats/", "");
