These two formats are among the most popular image formats on the web, yet they fulfill very separate roles. PNG is a lossless file type that supports full alpha channel, perfect for screenshots and illustrations. JPG uses efficient compression to create far smaller storage.
Main purpose to transform PNG to JPG is image size. Each PNG photo can be several times the size of the equivalent JPG. For websites, this means directly to poor page load times and poor PageSpeed scores.
Transforming PNG to JPG is the right decision whenever you are handling here photos that do not require a clear background. It is also recommended when you need to decrease storage for quicker email attachments.
Note that PNG to JPG conversion is not always recommended. When the PNG image contains a transparent background like a logo, changing it to JPG fills that transparency with white background, destroying the clear background.
