Optimizing image formats is crucial for faster loading on mobile devices, as it reduces file sizes and improves rendering times. Modern formats like WebP or AVIF provide better compression and quality compared to traditional formats like JPEG or PNG.

Example Concept: WebP and AVIF are modern image formats that offer superior compression rates and quality retention compared to older formats. By using these formats, you can significantly reduce image file sizes, leading to faster load times and improved performance on mobile devices. Ensure your server and client-side code support these formats, and consider fallback options for browsers that do not support them.

Additional Comment:

Use responsive images with the "srcset" attribute to serve different image sizes based on device resolution.
Implement lazy loading for images to defer offscreen images until they are needed.
Consider using a Content Delivery Network (CDN) to deliver images faster by caching them closer to the user.
Regularly audit your images using tools like Lighthouse to identify optimization opportunities.
