When converting PNG images with transparency to JPEG<\/a>, by enabling the Force conversion of transparent images <\/strong>setting, transparent areas are replaced with a solid white background color<\/strong>.<\/p>\n\n\n\n

PNG images can contain transparent pixels, which makes them ideal for logos, icons, and images that need to blend into different backgrounds. JPEG images, however, do not support transparency at all.<\/p>\n\n\n\n

By default, ShortPixel fills transparent areas with white during the conversion process. This ensures predictable and clean results in most common use cases.<\/p>\n\n\n\n

Once a PNG is converted to JPEG, transparency is lost. You can restore the original<\/a> backed-up PNG to restore transparency.<\/p>\n\n\n\n

Note: <\/strong>If the resulting JPEG image is later placed on a non-white background, the white areas may look unnatural around edges or cutouts. This is a limitation of the JPEG format itself and cannot be fully avoided.<\/p>\n\n\n\n
