5 Ways to Convert PNG to JPG for Free Online & Windows/Mac

Part 1. Difference Between PNG and JPG

PNG to JPG or vice versa seems to have no difference in the quality they produce, which is the truth. These formats can make 16 million or more color data to create the highest quality image possible. If your photos have an extension of .png or .jpg, we can assume that the image is very detailed because they are both raster formats. But if you dig deeper into their technicalities, data, algorithm, and more, you will see that they differ. There are advantages that the other format can’t offer you or the other way.

Before converting the format, let’s first learn and test PNG vs. JPG to see their differences. You can learn their differences with the chart we added below, so if you have spare time, you can read very detailed information you don’t know.
