What are the best practices for optimizing image loading on a responsive web page?
Asked on Dec 29, 2025
Answer
Optimizing image loading on a responsive web page involves using techniques that ensure images are loaded efficiently, improving both performance and user experience. This includes using responsive images, lazy loading, and modern image formats.
Example Concept: Use the element and srcset attribute to serve different image sizes based on device characteristics. Implement lazy loading to defer off-screen images until they are needed, and use modern formats like WebP for better compression and quality.
Additional Comment:
- Use the
element to define multiple image sources for different screen sizes and resolutions. - Implement
loading="lazy"ontags to delay loading images until they appear in the viewport. - Convert images to WebP or AVIF formats for reduced file sizes without compromising quality.
- Use a content delivery network (CDN) to distribute images closer to users geographically.
- Optimize images using tools like ImageOptim or TinyPNG before uploading them to your server.
