How does lazy loading images improve page speed?

Asked on Nov 29, 2025

Answer

Lazy loading images can significantly improve page speed by deferring the loading of images until they are needed. This reduces initial page load time, bandwidth usage, and improves user experience by prioritizing content that is immediately visible.

Example Concept: Lazy loading is a technique that delays the loading of images until they are about to enter the viewport. This reduces the number of HTTP requests made during the initial page load, decreases the time to first render, and lowers the total page weight, leading to faster load times and improved performance metrics such as Largest Contentful Paint (LCP).

Additional Comment:

Use the "loading" attribute with the value "lazy" in image tags to enable native lazy loading in supported browsers.
Consider using a JavaScript library for lazy loading if you need more control or support for older browsers.
Lazy loading is especially beneficial for pages with many images or long-scrolling content.
