A progressive JPEG loads in multiple passes — first a low-quality preview of the full image, then progressively sharper versions. This creates a better user experience compared to baseline JPEGs that load top-to-bottom.
Often yes — progressive JPEGs can be 2-10% smaller than equivalent baseline JPEGs, especially for larger images.
