Why Use WebP?
WebP is a modern image format developed by Google that uses both lossy and lossless compression. It typically produces files 25–34% smaller than JPEG at equivalent visual quality, and 26% smaller than PNG for lossless images. Smaller images mean faster page loads, lower bandwidth costs, and better Core Web Vitals scores — all of which are direct Google ranking signals.
WebP is now supported by all major browsers — Chrome, Firefox, Safari 14+, Edge, and Opera — covering over 95% of global browser usage. For modern web projects, switching to WebP is one of the easiest performance improvements available without any change to image dimensions or visual quality.
Common Use Cases
- Website performance
- Serving images as WebP instead of JPEG reduces page weight by 25–34% — a measurable improvement to LCP and page speed scores.
- E-commerce product photos
- Product image galleries often contain dozens of photos. WebP reduces total page weight significantly, speeding up catalogue pages.
- Blog & CMS images
- Replace JPEG hero images and inline photos with WebP to reduce bandwidth without touching image dimensions.
- Google PageSpeed optimisation
- Lighthouse and PageSpeed Insights specifically flag non-WebP images as an opportunity. Converting directly resolves this warning.
- CDN bandwidth savings
- Serving smaller WebP files from a CDN reduces egress costs at scale, particularly for image-heavy sites with global traffic.
- Progressive web apps
- PWAs targeting mobile users benefit most from WebP — smaller files load faster on 4G and 5G connections.
