JPEG vs PNG: Why the Same Image Can Have a Very Different File Size
Two image files can show almost the same picture yet occupy very different amounts of storage. A photograph saved as JPEG may be much smaller than a PNG version, while a screenshot with text and flat colours can behave quite differently. The reason is not simply that one format is newer or better. JPEG and PNG are designed to preserve image information in different ways. Understanding that difference makes it easier to choose a format for photos, screenshots, graphics, websites, and files you plan to edit again.
