JPG vs PNG — which compresses better?
JPG is best for photos — it uses lossy compression that removes data invisible to the human eye. Excellent compression ratios with minimal visible quality loss.
PNG is best for graphics, screenshots, logos with text, and images with transparency. Uses lossless compression — smaller than the original but not as small as JPG for photos.
