Pixy (hipixy.com) is a WordPress image optimization plugin from Net Stack Ltd. built to fix slow page speed and PageSpeed Insights warnings caused by unoptimized images. Once activated, Pixy works with a 'no-setup' automatic self-configuration flow: it converts images to modern next-gen formats (AVIF and WebP), compresses files in bulk across the media library, and applies intelligent lazy-loading so only visible images load immediately. Pixy also offers a real-time 'Speed Mode' that optimizes images on the fly versus a separate bulk conversion mode for existing media libraries, plus Real User Measurement (RUM) analytics that track PageSpeed and Core Web Vitals impact directly from real visitor traffic. The plugin targets Largest Contentful Paint (LCP) and Cumulative Layout Shift (CLS), the two Core Web Vitals metrics most affected by heavy or unoptimized images, with the goal of improving both site speed and search rankings. It requires WordPress 6.9+ and is designed to work across any WordPress hosting provider without manual configuration.
Key Features
Automatic AVIF/WebP Conversion — Converts images to modern next-gen formats (AVIF and WebP) automatically, with no manual setup required after plugin activation.
Bulk Media Library Compression — Compresses and optimizes the entire existing WordPress media library in bulk, not just newly uploaded images.
Intelligent Lazy-Loading — Defers loading of off-screen images so pages render faster, targeting Core Web Vitals like Largest Contentful Paint (LCP) and Cumulative Layout Shift (CLS).
Real-Time Speed Mode — Optimizes images on the fly as they're requested, as an alternative to running a separate bulk-optimize pass.
RUM Analytics & PageSpeed Tracking — Provides Real User Measurement (RUM) analytics that report PageSpeed and Core Web Vitals impact using real visitor traffic data.
Mobile-Specific Compression — Applies additional compression tuned for mobile devices to further reduce image payload on smaller screens.
