Images are a common resource on web pages; choosing the right image format and size can reduce loading times. For example, converting images to the WebP format can reduce file size while maintaining high quality.

<img src="image.webp" alt="WebP Image">

2. **Lazy Loading**

Lazy Loading is a JavaScript-implemented technique that loads images when the user scrolls into the visible area, reducing initial loading time and improving page load speed.

<img src="placeholder.jpg" data-src="image.jpg" class="lazyload" alt="Lazy Loaded Image">
<script>
  document.addEventListener("DOMContentLoaded", function() {
     let lazyImages = document.querySelectorAll('.lazyload');
     lazyImages.forEach(function(img) {
       img.src = img.getAttribute('data-src');
     });
   });
</script>

3. **Reduce HTTP Requests**

Reducing the number of resource files on a page can lower the number of HTTP requests, ***bine multiple CSS or JavaScript files to reduce the number of files.
