A portable network graphics (PNG) file is an image format file that uses data compression in a lossless form and is the preferred image format for Apple iPhone. When you take a screen capture on your iPhone, it will be automatically saved to the camera roll as a PNG file, and you can view it directly on the iPhone screen without installing any third-party iPhone apps. To load a PNG file, you must first save it to the iPhone’s camera roll.

How to find a PNG image on an iPhone

Press the home screen and power button at the same time to create a PNG screen capture.
