How can I optimize responsive-images for faster load time?
Asked on Oct 03, 2025
Answer
Optimizing responsive images is crucial for improving page load times and enhancing user experience. By using techniques like the `srcset` attribute and appropriate image formats, you can ensure images are served efficiently based on the user's device and screen size.
<!-- BEGIN COPY / PASTE -->
<img
src="default-image.jpg"
srcset="small.jpg 480w, medium.jpg 800w, large.jpg 1200w"
sizes="(max-width: 600px) 480px, (max-width: 1200px) 800px, 1200px"

<!-- END COPY / PASTE -->Additional Comment:
- Use the `srcset` attribute to define multiple image sources for different screen resolutions.
- Include the `sizes` attribute to specify the image display size for various viewport conditions.
- Consider modern image formats like WebP for better compression and faster load times.
- Implement lazy loading with the `loading="lazy"` attribute to defer offscreen images.
