Product images are the largest content type on online store pages. WebP format provides 25–70% smaller file size compared to JPEG and PNG while maintaining quality. This is one of the key metrics for Google PageSpeed and Core Web Vitals.
We connect WebP conversion to OpenCart and ocStore: newly uploaded images are automatically converted to WebP, existing images are batch converted. For browsers without WebP support (older Safari) the original format is retained.
On a typical store with 500+ products WebP conversion reduces total image volume by 40–60%. This accelerates page loading on mobile devices and improves LCP scores in Google PageSpeed Insights.
