See every featureSpeed AI helps merchants improve store loading performance by automating technical optimizations directly within Shopify. Slow page load speeds create friction for shoppers and negatively affect store browsing. Speed AI addresses these issues by compressing store images into modern WebP formats, removing leftover app code blocks from uninstalled apps, and deferring offscreen media.
WebPify SEO helps merchants speed up stores by converting product and content images to modern formats (WebP/AVIF), reducing file size and bandwidth without hurting quality. It supports one-click and bulk optimization, auto-optimization on product updates, safe restore from backups, and AI-generated alt text for accessibility and image SEO.
