How does lazy loading images improve my site's loading time?
Asked on Nov 19, 2025
Answer
Lazy loading images can significantly enhance your site's loading time 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 in the viewport. This is typically achieved using the "loading='lazy'" attribute in the tag, allowing the browser to load images only as the user scrolls down the page, thus improving initial load performance and reducing unnecessary data transfer.
Additional Comment:
- Lazy loading is particularly beneficial for pages with many images, as it reduces the number of HTTP requests made during the initial load.
- Modern browsers support native lazy loading, making it easy to implement without additional JavaScript libraries.
- Ensure that critical images, like above-the-fold content, are not lazy-loaded to maintain a good user experience.
