How does lazy loading images improve page load times?
Asked on Nov 05, 2025
Answer
Lazy loading images is an effective technique to improve page load times by deferring the loading of images until they are needed, which reduces initial page load size and speeds up rendering.
Example Concept: Lazy loading delays the loading of images that are not immediately visible in the viewport, using attributes like "loading='lazy'" in HTML. This reduces the number of HTTP requests and the amount of data transferred during the initial page load, leading to faster rendering and improved user experience.
Additional Comment:
- Lazy loading is especially beneficial for pages with many images or long content.
- It helps in reducing the Largest Contentful Paint (LCP) by prioritizing above-the-fold content.
- Ensure that lazy loading is implemented correctly to avoid images not loading when needed.
- Modern browsers support native lazy loading, making it easier to implement without additional JavaScript.
