How does lazy loading images improve my site's load speed?

Asked on Oct 29, 2025

Answer

Lazy loading images can significantly enhance your site's load speed by deferring the loading of images until they are needed, which reduces initial page load time and bandwidth usage.

Example Concept: Lazy loading delays the loading of images that are not immediately visible to the user, typically those below the fold. This is achieved by using the "loading" attribute set to "lazy" on image tags. By doing so, the browser only loads images as they are about to enter the viewport, which decreases the initial page load time and conserves bandwidth, leading to faster perceived performance for users.

Additional Comment:

Lazy loading is especially beneficial for pages with many images, as it reduces the number of HTTP requests during initial load.
It improves the Largest Contentful Paint (LCP) metric by prioritizing above-the-fold content.
Ensure that lazy-loaded images have appropriate dimensions to avoid layout shifts, which can affect the Cumulative Layout Shift (CLS) metric.
Most modern browsers support the "loading" attribute natively, making it easy to implement.
