URL: revokeObjectURL() static method

{{APIRef("File API")}}  {{AvailableInWorkers("window_and_worker_except_service")}} 

The revokeObjectURL() static method of the {{domxref("URL")}}  interface releases an existing object URL which was previously created by calling {{domxref("URL.createObjectURL_static", "URL.createObjectURL()")}} .

Call this method when you’ve finished using an object URL to let the browser know not to keep the reference to the file any longer.

[!NOTE] This method is not available in Service Workers, due to issues with the {{domxref("Blob")}}  interface’s life cycle and the potential for leaks.
