How can I optimize my site's image loading to improve overall performance?

Asked on Jan 02, 2026

Answer

Optimizing image loading is crucial for improving site performance, as it can significantly reduce load times and enhance user experience. Implementing lazy loading and using modern image formats are effective strategies.

Example Concept: Lazy loading delays the loading of images until they are about to enter the viewport, reducing initial load time and data usage. By using the "loading='lazy'" attribute in the tag, browsers can defer off-screen images, improving performance metrics like LCP (Largest Contentful Paint).

Additional Comment:

Consider using modern image formats like WebP or AVIF, which offer better compression than JPEG or PNG.
Implement responsive images using the "srcset" attribute to serve different image sizes based on the user's device.
Use a Content Delivery Network (CDN) to deliver images faster by caching them closer to the user's location.
Optimize images before uploading by compressing them without losing quality.
