Why Convert JPG to WebP?

WebP delivers the same visual quality as JPG in a significantly smaller file. For website owners, this means faster page loads, better Core Web Vitals, and higher Google rankings. Google PageSpeed Insights specifically flags JPG images that should be WebP.

25-35% Smaller Than JPG

WebP uses more efficient compression algorithms than JPEG. At the same perceived quality, WebP files are consistently 25-35% smaller.

Better Google Rankings

Page speed is a ranking factor. WebP images load faster, improving Largest Contentful Paint (LCP) — a Core Web Vital that directly affects SEO.

Save Bandwidth

If your site serves 100K image requests/month, switching from JPG to WebP saves 25-35% of your image bandwidth. Lower CDN costs, faster delivery.

Better User Experience

Users on slow connections (mobile, developing markets) benefit most from smaller images. WebP loads where heavy JPGs might timeout.
