9+ Best WordPress CDN Services (FREE & Paid) in 2021

There are endless possibilities to speed up your website. Using a CDN service is one of them.

So, what is CDN? CDN stands for content delivery network. It is basically a network of servers located around the globe. It hosts and delivers copies of your WordPress site’s content such as images, CSS, JavaScript, and video streams.

There is a possibility of getting confused about your site’s host and CDN. These two are different terms.

As you may know, the website database and contents are stored in a server. The server is located physically somewhere around the globe. When we enter a URL of a website, it shows us the contents from that server.

These were some basic facts we all know, right? Think about it. Your website server is located in the USA. So, if you try to reach that site from Japan, it has to travel a long distance before appearing to your computer screen. More distance means longer loading time, which is called latency as a term.

This is where CDN comes into work. It decreases latency by serving your website files from the nearest possible servers so that your visitors can enjoy a seamless experience on your site. Besides, CDN boosts your site’s performance and save bandwidth as well.

Let’s have a look at some of the best CDN solutions out there for WordPress websites.
