Any static or dynamic content, such as images, videos, documents, and CSS/JS files, can be cached by a CDN. There are multiple reasons why one should consider image CDN for their website, let’s look into it- 

Improved loading time 

Select the most efficient image format automatically. When possible, some smart image CDNs can also convert images to next-generation formats like WebP, which can achieve up to 40% more compression than JPEG without sacrificing quality. Every image’s compression quality is automatically adjusted based on what’s in it. A banner having some colors, for example, they are going to get compressed more than a high-resolution product photo. This option helps you achieve the ideal quality and size balance for each image. Dynamically adjust the format, quality, and dimensions based on device size, pixel density, and page layout to deliver responsive images to every screen. Given that images typically account for more than half of a page’s weight, incorporating a CDN for images can significantly improve loading times.

Better search ranking

A CDN improves the load time of your website, which leads to higher rankings: Google favors quick websites and ranks them higher in search results as a result. Your website needs to rank higher in order to attract more people to your website. It is advised to have your Interactive time below 3.8 seconds, but this metric varies by country and industry. You can use Chrome UX Report in order to see real user experience data on millions of websites and allows you to compare your own performance to your competition and the rest of the industry to get a clear picture of what you should be your goals. The best practice is to keep your Time to Interactive below 3.8 seconds, but this metric varies by country and industry.

More Conversions

Another major benefit of a fast page load time on both desktop and mobile is increased conversions. According to studies, when your website is fast, users are less likely to bounce and are more likely to complete the checkout process. They spend more time on your website and make more purchases. According to Google, reducing mobile site load times by one-tenth of a second can boost conversion rates by 8.4% for retail sites and 10.1 percent for travel sites. Furthermore, visually appealing images on your website are valued by visitors. The quality of your visual content can have an impact on the overall user experience, visitor engagement, and even purchase decisions. According to 83 percent of respondents in a Field Agent survey, product photos are “very” or “extremely” influential. You don’t have to sacrifice image quality for faster load times when using an image CDN. It will automatically optimize your images to be as light as possible while still being visually appealing. The ability to retrieve razor-sharp images will almost immediately impress customers, increasing their likelihood of purchasing any paid products or services you provide.

Higher level of security

Certain CDNs offer an advanced level of security options to their customers. These security options include multiple things such as SSL encryption which provides security to the data transfer between your website and users. HIPAA and GDPR also are meant to secure your personal information. You can also control who sees your content and when they can view it through CDN. Marketplaces and other websites that accept user-generated content benefit greatly from access control. So, if you’re building something like that, security should be a top priority. This CDN comparison can be extremely beneficial.

Shield your content from DDoS attacks

Thousands of computers flood your web servers with bogus requests in an attempt to make it unavailable to legitimate users during a DDoS attack. If all of your files are stored on a single server, such attacks can quickly take your content offline or take down your entire website. All cached content is fully protected when an image CDN is enabled. If an attack occurs, the load is distributed across multiple edge servers to avoid slowdowns and outages. Even if one server goes down, your content is safe on other servers, giving you more time to recover.

Reliable and Available 

Web server facing a physical damage or software is more common than you think. If one of the edge servers in a content delivery network goes down, the network will automatically reconfigure to deliver data from the next closest server to the user. The fact that a CDN distributes traffic between edge servers can also help you deal with traffic spikes more easily. If you run an e-commerce website and have a big sale on Black Friday, for example, you can rest assured that your site will not let you down at such a crucial time. No matter how large the load is, a CDN will be able to distribute it among servers.

Reduces long term cost 

CDN traffic is usually more expensive than traditional web hosting, but there’s no need to be concerned. Because of image optimization, using an image CDN lowers your traffic costs significantly: your images weigh less and the amount of data transferred is reduced. As a result, while it may be more expensive at first, it can help you save a lot of money in the long run. Take Shogun, a page-building platform for e-commerce teams and agencies, as an example. They wanted to provide a consistent user experience across all of their platform’s websites. They used Uploadcare Image CDN, which has an image processing engine built-in, to achieve this goal. They set up the CDN to adjust image compression, format, and quality automatically, which allowed them to maintain visual quality while reducing file size. If you’re new to CDNs and aren’t sure how much they’ll cost, ask your hosting provider for a list of your current bandwidth usage. There are numerous CDN pricing calculators available that can estimate your monthly costs based on your current usage and required locations.

Image CDNs come in a variety of flavors. Some will have more features than others, but they will all most likely help you save bytes on your images and thus speed up the loading of your pages. Aside from feature sets, cost, support, documentation, and ease of setup or migration are all factors to consider when choosing an image CDN.  It’s safe to say that an image CDN can improve your users’ visual experience. Better website performance and happier users are ensured by constant support and smart management of visual elements across all devices. All you have to do now is select an image CDN that complements your system’s capabilities. When tweaking the CDN settings to get the most out of it, you may have to go through a trial and error period. Once you’ve cracked the code, image CDN will assist you in scaling to unimaginable heights.
