Why WebP for websites

WebP is supported by every modern browser and is usually much smaller than PNG for the same image, including images with transparent backgrounds. Smaller images load faster, which helps Core Web Vitals and rankings. Use quality 80-90 for graphics with text, or switch on lossless by setting quality to 100.
