At quality 80-85 the difference is invisible at normal viewing distance and the file typically drops by 60-80%. The catch is that it is one-way: re-saving the WEBP repeatedly compounds the artefacts each time. Keep the SVG as the master and regenerate the WEBP from it whenever you need a new size. WebP既提供损失模式,也提供无损失模式,其中任一模式都具有阿尔法透明度和动画。
