How can I optimize image loading to improve page speed on mobile devices?
Asked on Mar 26, 2026
Answer
Optimizing image loading is crucial for improving page speed on mobile devices, as it reduces load times and enhances user experience. One effective technique is to use lazy loading, which delays the loading of images until they are needed.
<!-- BEGIN COPY / PASTE -->
<img src="image.jpg" loading="lazy" alt="Description of image">
<!-- END COPY / PASTE -->Additional Comment:
- Lazy loading reduces initial page load time by deferring off-screen images until the user scrolls near them.
- Ensure images are properly compressed and use modern formats like WebP for better performance.
- Consider using responsive images with the "srcset" attribute to serve different image sizes based on device capabilities.
- Implement a content delivery network (CDN) to decrease latency and improve image delivery speed.
