4 Shocking Reasons Why You Must Use CDN For Images

cdn for images

We all love adding beautiful images to our content to make it more appealing to our readers. We simply search the relevant images online and upload them to our site and add it to our content. This is what we do. Right? We want to spend more time writing great content and want our users to have a better experience.

Images are great. I love it and I prefer adding them to my content. But they hurt your site speed which leads to lower SEO rankings. Yes, that’s a fact.

Imagine you are sitting at a restaurant and waiting for your order for the past 10-15 minutes. How will your experience be? Will you continue coming to that restaurant again having known that the restaurant lacks good service? In the same way, your visitors won’t come to your site again if they happen to encounter that your site loads way too slow just because of those killer images.

Does that mean you should stop adding images to your content going forward? No. Images are great. In fact, I have been adding them to my content. And you should too. But the real truth is they affect your overall site speed if not optimized.

You must be thinking that I am contradicting myself here. Let me stress it and again say “You Should use images But…”

Enough scaring now let’s just take a breath and take you to the actual discussion of what is the objective of writing this article.

If you don’t want to be “that” restaurant then the best solution is to opt for CDN for images as this will take away a significant amount of load from your server. These CDNs minimize the loading time of your website as the assets like images and videos will be served through the closest servers possible based on the geographic location of the users.

In this post, we will discuss the nitty-gritty details related to images and how you can optimize your site speed gradually if you just opt for CDN for images.

But before we actually do that, let’s just first understand what CDN is and how they work. Also, we’ll take a look at some of the free cdn for images that you can use to optimize your site loading speed as well as SEO rankings.

What is CDN & How It Works?

CDN in web hosting is an acronym for Content Delivery Network, which is a cluster of servers distributed geographically. Their ultimate goal is to provide fast delivery of web content to its users, doesn’t matter where they are located. You must have heard about the term “caching” while optimizing your site speed.

Caching is a process that actually stores copies of your files in a cache or a temporary location so that they can be served quickly to its users.

Every time you hit a URL on your browser, it downloads a hell of a lot of data so that it can be displayed to you properly. But during that process, the page load times are generally high which Google hates the most, and eventually decreases the rank of your site.

Hence, browsers cache most of the content of your web page and save the copy of that web page on your device’s hard disk. So, the next you browse the same web page, the content will be fetched from your local device, and this way without hitting the server initially it will load much faster.

CDN basically caches your content like images, videos, webpages in proxy servers, a server that forwards requests coming from clients to other servers. And because these servers are more closely located to the user who is making a request, CDN is able to deliver the content more quickly.

What Are The Benefits of CDN:

There are countless advantages of using a cdn for images, but overall the benefits it provides are listed below:

  • Reduce latency
  • Improve website speed & overall performance
  • Quick content availability
  • Enhanced website security

Why Use a CDN for Images?

Because you want your website to load faster. Isn’t it?

It’s a great idea to store your images on multiple servers and serve them directly from there rather than hosting them on your site and then further adding it to your content. This way the website will load much faster. Also, if you can pre-optimize your images and then add them to your content would be a great thing to do. But this process is time-consuming and you don’t want to reiterate the whole process every time you want to add images to your content.

There’s a specific CDN for images called image CDN and can automatically optimize all your images on the fly. Some of the optimization tasks that these CDNs can do are listed below:

  • Automatically selects the most efficient format according to the end user’s device.
  • Automatically optimize the image size without losing its quality.
  • Perform several transformations like resize, cropping the image.

Are There Any Free CDN For Images?

How to Create a CDN for Images?

Getting started with any CDN is very easy and doesn’t require any other skills. For the sake of simplicity, I’ll be taking an example of Cloudinary as I use it highly for all my websites. But any other CDN would work the same.

Follow the steps below:-

  • Create a free account at Cloudinary
  • Login to the account with the credentials
  • Navigate to the Media Library and upload the image(s)

And you are done! Now the images will be loaded from the CDN and will take away the extra load from your server. Plus the great thing is that the images will be auto optimized on the fly and nothing extra has to be taken care of.

Should You Choose CDN For Images?

I mean why not?

It’s a great way to serve images as this would take off a large amount of load on your server every time your web page is being retrieved by your readers. This will not only increase your website speed plus the overall conversion rate would be much higher.

Optimizing images is really important if you don’t want to hurt your site ranking in Google. Google hates those sites that are slow and throw off their ranking to a lower one.

Let me know what are your thoughts on having CDN for all your website images.
