Combining lazy loading and image compression is one of the smartest ways to improve page load speed, user experience, and SEO. Whether you're running a blog, e-commerce site, or portfolio, optimized image handling gives your content a serious performance boost — especially on mobile.
In this guide, we'll show you how using these two techniques together will reduce bounce rates, increase your Core Web Vitals score, and make your content load lightning fast.
Lazy loading delays loading images until they're needed, while compression minimizes file sizes. When both are in place, users see visible content instantly — even before images load — which helps keep them engaged and scrolling. This approach is fully aligned with Google’s performance best practices.
What is Lazy Loading?
Lazy loading uses an HTML attribute like loading="lazy" to prevent off-screen images from loading immediately. This reduces initial page weight, boosts speed, and saves data for mobile users. Google supports it natively, so it also improves crawl efficiency.
How Image Compression Complements It
Even with lazy loading, uncompressed images will eventually slow down a page. That’s why combining it with a tool like ProCompressor is key. Compressing images before uploading ensures the smallest possible size with visually acceptable quality — exactly what PageSpeed Insights looks for.
