How can I optimize image loading for better performance on mobile devices?

Asked on Dec 13, 2025

Answer

Optimizing image loading for mobile devices is crucial for improving page load times and user experience. Techniques such as lazy loading, using responsive images, and compressing image files can significantly enhance performance.

<!-- BEGIN COPY / PASTE -->
    <img 
      src="small.jpg" 
      srcset="small.jpg 480w, medium.jpg 800w, large.jpg 1200w" 
      sizes="(max-width: 600px) 480px, (max-width: 1200px) 800px, 1200px" 
      alt="Responsive Image" 
      loading="lazy">
    <!-- END COPY / PASTE -->

Additional Comment:

Use the srcset attribute to specify different image sizes for various screen resolutions.
Implement lazy loading with the loading="lazy" attribute to defer off-screen images.
Compress images using tools like ImageOptim or TinyPNG to reduce file size without losing quality.
Consider using modern formats like WebP for better compression and quality.
Ensure your server supports HTTP/2 for faster image delivery.
