In today’s world, the most important thing, when it comes to your site, is its loading speed!  If your website loads slowly, you will lose a lot of visitors because no one is patient enough to wait for the site to load as they can just go to some other site. So you have to pay attention to make your site load faster so that no one leaves your site because of its speed.

You might have already optimized everything on your blog, from optimizing the images to optimizing the JavaScript and CSS files and even enabled the Gzip compression, but if you are not yet using CDN for your site, then you haven’t yet optimized the speed fully.

It’s always good to have your site powered by a Content Delivery Network. Not only does a CDN save bandwidth costs from your hosting provider, but your site becomes insanely fast and tends to rank higher in the search engines. If you start using a CDN (Content Delivery Network), the speed of your WordPress blog will improve drastically and you will be able to provide all the content to your visitors easily so that they don’t just leave your site.

What is a CDN (Content Delivery Network)?

A CDN is a network of multiple servers that are located at various places in the world. It caches all the static content of your site like the images and CSS-JavaScript files and stores on its servers.

So when a person visits your site, the static content will be delivered to them through the server that is closest to them. You can refer to the below image from GTMetrix to understand how the data is delivered.


As you can see, when that data is delivered from a distance, it will surely take more time to load. But, when the same thing is done through a server that is close to them, the site will be loaded very fast.

So now that you know why you should start using CDN, you will start looking for the best ones out there. You have no need to look any further as below is a complete list of some of the best CDN services for WordPress blog that are absolutely free to use.

4 Free CDN services to speed up WordPress

Photon by Jetpack

Swarmify, (previously known as SwarmCDN) is a peer-to-peer (P2P) based content delivery network that offers 10GB bandwidth (only for images) in their free plan. To try it out, download the WordPress plugin and give it a go.

It is interesting to note that Swarmify works in a slightly different manner:

Let’s say a group of people are browsing your site. Think of them as the first ‘peer’ in P2P. When a new visitor (peer) arrives, the images are served from the already existing group of users (the previous peer). This saves your server’s bandwidth, and improves loading times, since the peers are usually closer to one another.

Swarmify also offers video CDN, which is only a part of their paid plan.


jsDelivr is a CDN service for hosting JavaScript files. If you run a WordPress blog, then there will be a lot of JavaScript files in your blog and most of them will be run through this network.

The most important use of jsDelivr is when you use some custom JavaScript code on your site, and you have to host it. If that’s the case, you need to use the service and also install the free WordPress plugin on your blog.
