If you have stumbled upon this content, there is possibility that you are diving into the universe of image CDNs, keen on grasping their essence and understanding how Image CDNs work. Alternatively, perhaps you are already familiar with the concept and are aiming to explore deeper into the pivotal aspects that can amplify your website’s efficiency.

Be as it may, you are in the correct place!

In this article, you will understand the basics of CDN and also the importance of specific characteristics within an Image CDN.

Let’s get started on this right away. We will first examine the more general definition of content delivery networks (CDNs) and then examine the intricacies of image CDNs.

Consider this scenario: You are running an e-commerce shop situated in India, hosted on a server in Bangalore. Now, envision users accessing your site from diverse regions, or even globally, a hundred miles away.

Geographical distances between users and your server may cause load times to lag, which can discourage customers, negatively influence their experience, and ultimately lower conversion rates. Because the load time increases with server distance.

Well, this is where Content Delivery Networks (CDNs) come into play. These networks involve dispersed servers globally, retaining duplicates of your website’s content. When a user demands your site, the CDN dispenses content from a server near the user’s location. This diminishes latency, ensures faster load times, and enriches user experience.

This is especially crucial in today’s visual-centric online environment, where images and visual content play a key role in engaging users and conveying information effectively.

Images introduce intricacy to content delivery due to variables like format, image size, image compression, and image quality. And a lot more. Hence, Image CDNs are customized to boost and disseminate images efficiently.

An image content delivery network (CDN) is just a conventional CDN with a few software upgrades on top to improve the functionality of the underlying CDN for real-time image optimisation and transformation, making it more appropriate for image delivery.

This is how it operates:

The delivery signifies that how quickly an image gets sent to the user’s device. This part is done by CDN as mentioned in the above paragraph. Some of the top-performing content delivery networks are AWS CloudFront and Akamai assure prompt transmission of images to users globally. They are massive as they have their network spread worldwide.

We must incorporate the special functionality needed for editing and optimising the images into the content delivery network. Transformation to the WebP format, for example, can reduce image sizes by up to 80%. You may crop, resize, add a watermark, etc. to images with this processing feature.

Dedicated “processing servers,” which are distinct from the servers in the content delivery network, are used to carry out this operation. The processing servers carry out the majority of the work in configuring the image CDN. These would always be localised in a few regions and significantly fewer in number than the servers in a content delivery network.

While some Image CDNs primarily concentrate on delivery and processing, others present integrated storage or media libraries. This attribute streamlines image management and facilitates seamless amalgamation with the CDN. Not only does this media library streamline image submission and administration, but it also makes it easy to get started with the service.

Consider Percept Pixel as an example. It amalgamates a media library for “storage”, AWS CloudFront for “delivery”, and for processing servers across numerous regions, crafting a resilient Image CDN infrastructure.

One of the primary reasons why image CDNs are important for enhancing page speed is their ability to cache and deliver images from servers that are closest to the user’s location. This geographical proximity reduces latency and minimises the time it takes for images to load, resulting in a faster and more seamless browsing experience.

Upon a user’s solicitation of an image, the CDN facilitates its delivery through a sequence of stages:

While the specifics may fluctuate, the core functionality remains consistent across Image CDNs.

When assessing an Image CDN, ponder over these crucial features:
