How can I efficiently lazy-load images to improve page speed?
Asked on May 09, 2026
Answer
Efficiently lazy-loading images can significantly enhance page speed by deferring the loading of images until they are needed. This reduces initial load time and conserves bandwidth.
<!-- BEGIN COPY / PASTE -->
<img src="image.jpg" loading="lazy" alt="Description of image">
<!-- END COPY / PASTE -->Additional Comment:
- Use the "loading" attribute with the value "lazy" on
elements to defer off-screen images.
- Ensure that images have descriptive alt attributes for accessibility and SEO.
- Consider using responsive images with the "srcset" attribute to serve different sizes based on device resolution.
- Test lazy-loading performance using tools like Google Lighthouse to ensure it improves LCP (Largest Contentful Paint).
