Real Before and After Example
A website owner has ten PNG product photographs. Each image is about 4 MB and measures 4000 by 4000 pixels. The files are too large for fast website loading.
The user selects WebP, chooses Recommended quality and limits the maximum width and height to 1600 pixels. The converted images are smaller, easier to use online and downloaded together in one ZIP.
