Uses of PNG Files
PNG files can be very large at times and hence consume a lot of disc space. In such cases, you can also face difficulty in sending these files in email. They also slow down the web page when you open a PNG file there. You can consider using these files if it doesn’t matter to consume so much space or slow web page loading, because PNG files do not compress the image quality like other lossy formats like JPEG files.
PNGs are useful when you deal with sharp contrast. For example, when there are lines or text in the image, as well as large areas of solid color, you can use PNG files. PNGs are best for screenshots and illustrations, while JPEG/JPG are suitable for “real” photos.
If you want to edit an image several times, then you can consider using the PNG format over JPEG. With the JPEG format, you will have to deal with the lower image quality after editing the image for several times as it involves generation loss. But PNGS are best to retain the image quality in such cases.
