How to Serve Scaled Images on Your WordPress Website


Did you indicate that you should only run a Web site through a performance test tool to “provide an enlarged image”? By default, the tool will tell you that you need to resize the image to match how it will be displayed on your site.

Fortunately, WordPress has some useful tools. You can use the image optimization plugin to automatically deliver a scaled image, or you can use several techniques to adjust the image yourself. This will go a long way in optimizing page load time and improving bounce rate.

This section explains why it's important to serve resized images correctly. Then we provide a convenient solution to make the process as easy as possible.

Why You Should Provide Extended Images

Expanded images are basically resized to the exact size you are using. On the one hand, too small and enlarged images are blurry. On the other hand, the browser shrinks images that are too large, but unnecessarily increases the file size of the page.

Also, large images will make the browser spend time and resources instead of loading the page itself as soon as possible. This can significantly slow page load times and negatively impact the performance of your website. For example, if your theme shows an image of 100 x 100 pixels, you want to load an image that is exactly 100 x 100 px. When you load an image that's 50 x 50 pixels in size, it looks blurry when resized to up to 100 pixels. On the other hand, if I load an image that is 200 x 200 pixels, the image looks good but still only displays at 100 pixels, so there is no need to increase the page size.

Of course, slow pages keep visitors away. Not only can you promote a user experience (UX) that your users don't like, but it can also boost your bounce rate when users get frustrated and click on your site.

Almost all performance testing tools provide scaled images:
