How can I optimize image loading to improve my site's rendering performance?

Asked on Jan 13, 2026

Answer

Optimizing image loading is crucial for enhancing rendering performance and improving metrics like Largest Contentful Paint (LCP). Techniques such as lazy loading and using modern image formats can significantly reduce load times.

<!-- BEGIN COPY / PASTE -->
    <img src="image.webp" loading="lazy" alt="Description of image" width="600" height="400">
    <!-- END COPY / PASTE -->

Additional Comment:

Use the "loading" attribute with "lazy" to defer offscreen images until the user scrolls near them.
Convert images to modern formats like WebP or AVIF for better compression and quality.
Specify width and height attributes to prevent layout shifts, improving Cumulative Layout Shift (CLS).
Consider using responsive images with the "srcset" attribute to serve different sizes based on device capabilities.
Leverage a Content Delivery Network (CDN) to reduce latency and improve delivery speed.
