When to Convert
Common scenarios where this conversion is useful
Website image optimization
WebP images load faster, improving your website's Core Web Vitals scores. Converting JPG product photos, hero images, and thumbnails to WebP can cut page weight by 25-35%.
Reducing CDN bandwidth costs
Smaller images mean lower data transfer costs. For high-traffic websites serving millions of images, the bandwidth savings from WebP add up significantly.
Mobile-first web development
WebP's smaller file size is especially important for mobile users on slower connections. Convert your JPG assets to WebP for faster mobile page loads.
