5 Best Free CDN Services for WordPress Blog

If you are serious about your blogging journey, then you will have to first create a blog through which people will recognize you.

And if you are creating a blog, you have to maintain it properly and
make sure that it’s the best in every category.

The most important thing, when it comes to your blog, 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.


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.

Why use a CDN

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.

1. CloudFlare

CloudFlare is, hands down, the best CDN service for WordPress that is absolutely free. The data centers are located all across the world to serve you the content at blazing fast speed.

The implementation is extremely easy – you create a free account then you add your blog URL and once CloudFlare checks your websites, it will provide you with custom nameservers and you just have to point your domains to that nameservers and you are done!

See, that was easy!

The reason CloudFlare is extremely popular is that it makes your site load extremely fast and on average the site sees 65% fewer requests and saves around 60% bandwidth.

Check out the below network map of the locations of all the 30 data centers around the world.

2. Photon by Jetpack

If you are running a WordPress blog, then I am very sure that you are using the Jetpack plugin as well. The plugin is a must have for WordPress blogs because it offers many options to make your blog user-friendly. One of them is Photon CDN!

Photon CDN
  • Save

This Photon feature is not like the other CDN services for WordPress, but if your blog contains lots and lots of images, then it would be a great help to activate this feature.

Photon is a content delivery network that loads images on your blog through the powerful WordPress.com servers.

To activate Photon, you just need to install Jetpack plugin on your blog and then activate the Photon feature from your site dashboard.

3. SwarmCDN

This service is relatively new compared to the others in the list, but since it offers a free plan with 250 GB of free transfer, I had to mention it in this post.

Swarm CDN
  • Save

If you are truly looking for a CDN service, you need to try out SwarmCDN as it offers a free transfer and is also available in around 196 countries worldwide.

4. jsDelivr

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.

jSDelivr CDN
  • Save

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.

5. Coral CDN

Coral CDN is a P2P (peer-to-peer) based content delivery network and a project from MIT. The service is free of cost because since it relies on the P2P network, billions of computers are connected across the world, making it absolutely free.

The way Coral CDN works, according to their WordPress plugin is by serving the static content through their servers by appending ‘nyud.net’ to the URL.’

Other Paid Options:

There are these 5 CDN services that are absolutely free to use to speed up your WordPress blog, there are other much better options out there if you are willing to spend money.

Here are the brief introductions for all the paid CDN networks:

  1. MaxCDN – The best one there is! All the major sites use MaxCDN to deliver their content and keep themselves blazingly fast. The pricing starts at $9/month.
  2. Incapsula – This CDN service not only makes your site load fast but also provides website security and DDoS protection as well. The content is delivered through their globally powered network. The pricing for Incapsula starts at $19/month.
  3. RackSpace – This CDN service is a pay-as-you-go service. The pricing starts at $0.00014 for the first TB of storage and $0.12 for the first 10 TB of CDN bandwidth. Check out their pricing structure for a better idea.
  4. Amazon AWS – The Amazon AWS offers a free trial that includes 5 GB of Amazon S3 storage, and 20000 get requests and 2000 put requests. You can visit the pricing structure of Amazon CDN services to know more about it.

Wrapping Up:

If your website attracts around 50K to 100K UV a month, then you should go with a free CDN and also keep CloudFlare as your number one CDN.

But as your traffic increases, you should start considering the paid options because if you don’t spend money on keeping your site running, you are going to lose your loyal readers and as a result, a lot of money.

  1. I have been using cloudflare CDN for 6 months and with my experience I found it a great tool to increase my site speed as well as it also prevents other unwanted bots crawling my site, but I must say that today I learn something new here in this blog post i.e SwarmCDN, jsDelivr and Coral CDN.

  2. I use keycdn which is great for a WordPress site. The CDN offers great features and even better prices. Very happy with it.

  3. I am using cloudflare from last 2 days. but now i am not able to open my site and cloudflare site. if you are not able to cloudflare, you cant open any site that are using cloudflare. read your post, going to swarmcdn.

  4. Hello Ankit,

    I have tried CloudFlare and sometimes my sites not working with CloudFlare. CloudFlare gives caching, loading etc errors. I don’t think it is good idea to use CloudFlare.

  5. Nice Post Ankit about free WordPress CDN services.

    Jetpack is lightweight and has very much a couple of great elements. It’s likewise upheld and sponsored by the creators of WordPress.com, so you can believe it. Jetpack is one of a chosen few plugins that I introduce on each site I fabricate. There are a couple of absolute necessities in this world, yet this plugin is one of them.


  6. Nice Post Ankit,
    I am using Cloudflare for my blog and I found it to be very user-friendly. This CDN provides plenty of useful features.

  7. Website speed plays a vital role to success in online business and search engine loves the speedy sites .. am using cloudinary and want to use other cdn also but my site was developed in asp.net , can i use this services … thanks in advance Ankit and appreciate your time to share your knowledge about content delivery network

    • Hello Muhammad,

      I haven’t tried KEYCDN. As of now, I’m using MaxCDN and it’s performing pretty well.

      Have you ever tried it?

      Share your experience with me 🙂

  8. Thanks for sharing this. Very Impressive.

    But among them from my point of view clodflare is the best. Still my website is running very fine with cloudflare cdn serviece. MaxCDN is also good for paid authors. You will also get lots of coupons for this.

  9. Thank you for great post. Very usefl information, after CDN implementation website got 98/100 in gtmetrix.com. I would like to add, that after registraton in CloudFare somebody has to change DNS zone by domain registrar (add DNS from CDN provider) + DNS zone by hosting provider (delete previous NS records and add new NS records from CDN provider).

  10. Hie Ankit, thanks for sharing this so useful Info.
    I don’t like cloudflare (Free plan) now and love the Jetpack Photon feature. A lot of bandwidth is saved coz of it,
    Just wanna know, Does using Photon in jetpack Affects our SEO?

    As the images are cashed and delivered from their server, So are that images also index in google, if so than it would be dpublicate in google search?

    Please help me through this..

  11. Nice, Article Ankit I’m currently using Cloudflare and have used MaxCDN both are good. Might be you’d heard about DDos attack on Cloudflare, which actually makes me believe in their protection too.

  12. Nice Article, CloudFlare is the best free CDN, but some times faces site loading problem. Good to know about others free CDN services.

  13. Ty, Although. I dont really understand the wrapping up section. What happens after 100k UV? Cloudflare says they give unlimited bandwidth. The user doesnt care and doesnt know how much you spend to run a website. So where is the drop off on Free CDNs? Are you saying that they throttle you at a certain UV limit without telling you what the limit is?

  14. I was using cloudflare cdn but was having higher time to first byte issue. So i dropped the whole idea of using a cdn and used w3 total cache with fast velocity minify istead. My site is super duper fast now and honestly, there’s no need of a cdn now, apart from the ddos attack factor.
