Hello guys, today is the first day of 2021 and I would say Happy New Year 2021, hope in this year will be better than the last. So today I want to write an article about list unlimited free image cdn. Why? Because using cdn for image will make your website strong in high traffic and will saving your cost about the image bandwidth.

Actualy, there are many image cdn services out there but to find that giving 100% free services and simple to use is really hard. Most of them is required to reupload the image and not 100% free (there is hidden price if you reach the storage / bandwidth limit). Let’s say your article is very much, more than 100 articles, are you want to reupload all images again? For me, I don’t want to do this. So I will list the free image cdn which is no need to reupload the image, just url only and we get the cdn for free.

Conclusion

All free image CDN in this article mostly using Cloudflare CDN as backbone server. So why do we just using Cloudflare directly? Well, Using Cloudflare is not simple as we thought. Do you think as we already connected with Cloudflare DNS means we will get the cache feature? The answer is Nope, you have to know the basic knowledge about how proxy cache works properly between your server and cloudflare server, it’s really complicated to configure, if not, everything will be useless. For your information, I found many tutorial setup CDN using Cloudflare at the google search engine and 80% of them got wrong or useless. The cache seems to work normally, but actually is not. Are you able to make sure for example if the cloudflare server response 304 then the origin server return empty response? I doubt it.

Yeah that’s all for the list free image CDN. I suggest you to choose or pick one of these, because they are having pros and cons. Moreover, they are professional and already been used in many big websites. Sorry I’m not list the image cdn that giving free services but there is still exists for a hidden price or limited in storage or bandwidth.

I will always update this article in the future if I found the 100% free image cdn anymore.

So, if you know about 100% free image cdn that is not listed in here, just leave at the comment below.

Thank you for reading my article, hope this will be benefit for us.
