This guide provides multiple methods for converting PNG to JPG and vice-versa on macOS, catering to different user skill levels and preferences. Whether you're a casual user or a seasoned pro, you'll find a suitable solution here.
JPG (Joint Photographic Experts Group) and PNG (Portable Network Graphics) serve distinct purposes. JPGs, ideal for photographs, offer smaller file sizes due to lossy compression and lack transparency. PNGs, better suited for graphics and images, maintain higher quality with lossless compression and support transparency, resulting in larger file sizes.
