Your website is hosted on a server and the server is located in a specific place. Let’s assume it is located in Singapore, so when a user will open the website from Singapore or Malaysia, the server response will be blazing fast. But the problem comes when the user is located very far away from the server location. That’s where free CDN (Content Delivery Network) comes handy. CDN is the best way to speed up your website throughout the world.

Why use Content Delivery Network (CDN) for Website?

1. Browser load simultaneously more elements of a website.

When anyone opens a website in a browser, the browser downloads all the files and data but with a limit of 4 concurrent downloads. The 5th download is blocked which create long loading time.

CDN files are hosted on a different domain. CDN permits the browser to download an extra 4 download.

2. Decrease the load on your server.

Using a CDN means reducing the bandwidth of your server. It helps in boosting performance and also saves money.

 3. High Capacity servers

If you are using a Good and reputed CDN then your static files are on a high capacity infrastructure. Cloudfare, Amazon, and maxCDN use very high capacity servers which are much better than your web host servers.


These are the best free Content Delivery Networks (CDN), providers. Cloudfare is easily the best CDN in the list. Incapsula is also an emerging player and definitely worth a shot if you are looking for free CDN providers.

Jsdelivr is on other hand is an open source and completely free CDN. Targeting only JavaScript files, you use jsdeliver with other CDN provider like Cloudfare. Open source project always gives best features free of Cost and that’s where Coral CDN comes in. An MIT project, this free CDN use a different concept than all other CDN on this list, and it actually works.

If you ask me, I recommend you to use Cloudfare and to increase the speed further you can host your image on some other Image hosting websites like Flickr.
