Improving User Experience With Free Image CDNs

Content Delivery Network - free image CDN

Images have become an integral part of most websites owing to their impressive benefits today. They help attract users’ attention, improve SEO, and influence customers’ purchasing decisions. But images are also often the largest and most resource-intensive assets on a web page. Hosting too many large images on your web server results in a slow-loading web page or longer loading times. Plenty of surveys show how slow loading time negatively affects user experience, sales, and even SEO. However, optimizing images can have a significant impact on the overall website performance, which, in turn, improves user experience. This is where the need for a free image CDN arises.

But what is an image CDN? Can we get image CDN free hosting? How does it impact user experience, and how can it be implemented on your website? This article will answer all these questions.

What Is an Image CDN and How Does It Help Improve User Experience?

A CDN (Content Delivery Network) refers to a network of servers and data centers distributed worldwide. The purpose of using a content delivery network service is to cache content near the end-user and reduce latency in order to improve load times. In other words, using a CDN, we can deliver content to users over the internet faster, without any quality loss. CDNs can deliver different types of content faster, such as images, videos, HTML pages, and more.

An image CDN is just like a regular CDN but specializes in optimizing, transforming, and delivering images. In other words, a free image CDN is tuned specifically to serve pictures faster. It’s because delivering images on their website is a bit complicated – we need to consider image dimension, quality, format, aspect ratio, and more. Moreover, a good image CDN service uses powerful image optimization algorithms to deliver images that load faster. Some problems that a free image CDN solves include network congestion, high amount of latency, and slow loading times.

How Does a Free Image CDN Work?

The CDN service stores the cache copies of the image on several servers present in different locations. When a user requests an image, the CDN service delivers it quickly using the server closest to the user.

What Are Some Free Image CDN Hosting Providers?

There are plenty of free image CDN hosting providers available in the market. While free image content delivery networks are tempting, they offer limited features, such as limited bandwidth and storage. Thus, in many cases, it’s best to use a paid image CDN service that offers better features, security, performance, storage, and bandwidth. You may find the best image CDN providers a bit costly, but they’ll save you money in the long run by improving your website or web app performance.

Here are some of the free image CDN services available in the market:
