Technology has evolved a lot and we are living in a fast-moving world. From bullet trains to 5G telecom technology, speed can be noticed everywhere.
Website is vital for modern businesses and optimization drives more conversions. So a fast-loading website is also necessary for both the best user experience & conversion.
There are a lot of factors that affect website speed. But multimedia elements like images play a vital role in page loading.
Images are resource-heavy and put stress on the server. You can use an image CDN to host and serve images dynamically. I will show you some of the best CDN for images.
So let’s get started.
What is Image CDN?
I know you might have an understanding about this, as you have landed here using the search term best image CDN or similar queries. Before we discuss image CDN, let’s see what CDN is only.
A content delivery network (shorten as CDN) is a network of geographically distributed servers across the globe that deliver web content from the server closer to the user’s location.
An image CDN is specially deployed for serving images instantly. Apart from quick delivery, this system can transfer images based on shape, format, file size, and appearance dynamically.
Images are mostly responsible for website loading slowly. An average page puts a payload of 2MB on the server whereas 50% of them are images. Using an image CDN these elements put less load on the website hosting server.
After you upload an image to the CDN server the system automatically creates several copies and send them to different servers. When a user requests a webpage, the images will be dynamically served.
Instant and unexpected traffic surges can lead to outages or downtime. Content delivery networks dynamically distribute loads and handle extra spikes in traffic. One of the biggest advantages of image CDN is image optimization.
The CDN system analyzes user device size and location to serve better responsive images. Optimized images also serve smaller images and save bandwidth.
Why Do You Need a CDN for Images?
To be honest an image CDN does the same as a regular CDN server. The main difference is the enhanced features that are specially designed for images.
There are several benefits of an image CDN. So let’s check what these are.
1. Better loading time
Content delivery network deploys multiple servers around the world. Whenever someone requests a file, it delivers from the nearest server. So the response time would be low and make your website faster.
2. Improve User Experience
In this high-speed internet era, no one wants to visit a slow website. Slow loading images on a page put a serious impact on the user experience. Ecommerce websites and blogs add images to almost all pages.
If images take too much time to load then the user will leave without taking action. Image CDN delivers images dynamically you won’t face performance issues.
3. SEO Benefits
Websites should apply everything that can boost ranking in SERP. Now Google is putting more emphasis on website load time and placing in higher positions accordingly.
There are over 200 ranking factors Google considers to keep a website in top SERPs. But speed is one of the top SEO factors these days after mobile-first indexing is rolled out.
Image CDN servers make the images delivery process faster and speed up page loading. Study shows that 47% of customers expect a webpage to load in 2 seconds or less. Website conversion rate is also affected by page design and images on the page. Using a CDN can boost your organic ranking and drive more conversions.
4. Specially Designed for Images
Image CDN offers several features just for robust image delivery. The system automatically selects the most efficient format of an image. Some content delivery networks convert images to next-gen formats like WebP when needed.
The system also automatically adjusts the quality of high-resolution images. It would maintain the perfect balance between image quality, dimensions, and size. Image CDN also delivers responsive images based on the device screen size.
5. Reliable
Web servers are always associated with the risk of hardware failure and software crashes. Assume a condition where you have an eCommerce website and it goes down during the festival sale.
Because it can’t handle instant traffic spikes. You would miss thousands of sales in such an important moment.
But CDN services have many servers each having a copy of the website files. If one server goes down then data will be delivered from another server instantly.
CDN uses a load balancing technique that will distribute the load in several servers regardless of the traffic size. So you can let visitors browse the website without disturbing the user experience.
6. Better Security
Cyber threat is a major concern nowadays. So hosting companies are providing simple SSL certificates to secure the data transferred between users and websites. But it is not sufficient to hide from spammers.
Web servers with bugs let attackers steal data from the server. But content delivery networks are associated with hundreds of servers in different locations.
They use several security layers to prevent themselves from cyber-attacks. However, no server in the world that can’t be hacked. If any CDN server faces a cyber-attack, then numerous servers already there having the copy of images.
