Looking for a free CDN? Although most web-masters claim that free Internet services are not worth trying, these 10 advanced providers debug this myth! Here are 10 Best free CDN solutions for WordPress to speed up your site and increase performance. Some of them go with generously long trial periods (up to 12 months), others are absolutely free for widespread scripts, including jQuery, Bootstrap, etc.

Why Using CDN?

Given that today the average Internet speed in advanced regions exceeds 10 Mbps, and some users already enjoy speed up to 1 Gbps, users become more intolerable to slow website loading. Our patience is limited: according to statistics, visitors who have to wait page loading for more than 3 seconds tend to abandon website and turn to competitors’ projects.

Therefore, it’s always beneficial to have your website powered by a CDN (content delivery network). It not only cuts on bandwidth expenses for your hosting provider, but makes your project incredibly fast and contributes to higher ranking in search engines.

If you don’t know what CDN is, we’ll cover the basics. CDN is a system of servers that are spread across the globe to transfer static website files (images, PDFs, static libraries like JavaScript and CSS files) to the visitors. Usually, a website has only one source of content – the origin server. It’s enough, if you don’t have many visitors. But as your website grows, it gets more traffic, so the amount of time needed for it to load also increases. CDN distributes your content over edge servers, all of which take the vast majority of traffic offloading your origin server. The system chooses the server that’s closest to the visitor, which reduces the distance for content to travel and latency.

Now when you get the idea of what CDN is, it’s time to enlist the best free solutions for WordPress blogs.
