WebP plugins automatically convert uploaded JPEG and PNG images to the WebP format — a modern, lossy and lossless compression format developed by Google that produces files 25–35% smaller than equivalent JPEGs at comparable visual quality. Smaller image files directly improve Core Web Vitals scores, particularly Largest Contentful Paint (LCP), which is a key Google ranking factor. These plugins are widely used by site owners optimising for PageSpeed Insights scores, improving mobile performance, or reducing server storage and bandwidth costs. Many WebP plugins work in combination with CDN and caching solutions, serving WebP to supported browsers while falling back to the original format for older clients that do not support the format natively.
