Why convert JPG to WebP in 2026?
WebP is Google's modern image format built for the web. At similar visual quality, WebP files are often 25–35% smaller than JPEG, which directly improves Largest Contentful Paint and reduces bandwidth bills on high-traffic sites.
If you still serve large JPEG hero images, converting to WebP is one of the fastest wins for Core Web Vitals without redesigning your site.
