Changing your PNGs into JPGs while retaining image quality.
PNGs (portable network graphics files) are great for image files due to their lossless compression and compatibility with web browsers. However, if your file has a lot of data, you’ll want to convert PNGs to a JPG (joint photographic experts group) image format. JPGs are raster images that use lossy compression, so your converted files will be a smaller file size, but won’t typically reduce much in image quality. JPG conversion, for example, is a good choice if you need to email or more simply transfer large PNGs.
