Because JPG contains much less data than PNG, it does a better job of giving you smaller file sizes that don’t take up a lot of disk space. That makes JPG the preferred format for uses that require faster loading times and less storage.

JPEG typically creates much smaller files compared to PNG, especially for photos. This is one of the reasons why this format is so popular with digital photographers and why digital cameras don’t allow you to shoot in PNG.
