Why Format Choice Matters
In the world of web performance, every kilobyte counts. Large images are the primary reason for slow websites.
Google's Core Web Vitals metrics penalize slow sites. Using modern formats like WebP is one of the easiest ways to improve your Largest Contentful Paint (LCP) score. However, compatibility still matters—if your users are on very old devices, they might not see WebP images at all.
