 Images make up most of the weight and file requests for most web pages. By optimizing images, you can make your website lighter and faster. If you compress images correctly, you don't need to compromise on the quality either. Here's our page. It uses a lot of imagery. Let's take a look at the lighthouse report. It tells me that I can save over 1.5 megabytes by optimizing some of the images. Let's do that. There are many optimizing tools. I am going to use Image Optim. First, I'll make three copies of my JPEG file to be able to test the difference. First, I optimize the image, preserving the same quality as the original. That saves about 50 kilobytes. The second image I optimize with 80% quality setting. That gives me over 250 kilobytes savings in the file size. Lastly, I optimize an image with 60% quality setting. Now the file is much, much smaller. Let's display these three images side by side. Can you see the difference? The difference is unnoticeable. I can go ahead and optimize all images in my folder with the 60% quality setting. Let's reload the page and check the network panel. Now all the images weigh only 1.3 megabytes. Did it influence the user experience on our site? Well, let's see the results. This screenshot strip in lighthouse looks much more reasonable right now. Users on 3G network can see the pictures load faster than the old site. Remember, for the web usage you can often optimize images heavily without reducing display quality.
