The createObjectURL() static method of the {{domxref("URL")}} interface creates a string containing a blob URL pointing to the object given in the parameter.

For more information, see blob URLs.

To release an object URL, call {{domxref("URL.revokeObjectURL_static", "revokeObjectURL()")}}.

[!NOTE] This feature is not available in Service Workers due to its potential to create memory leaks.
