Have you ever wondered how Shopify loads your online store lightning-fast, no matter where your customers are located? The answer lies in Shopify’s powerful CDN (Content Delivery Network).
Shopify has established itself as a reliable and powerful e-commerce platform, enabling businesses to create and manage online stores easily. One key factor that enhances the performance of Shopify stores is the CDN. The CDN is essential in e-commerce, ensuring fast and efficient content delivery, improving user experience, and increasing sales.
Shopify CDN delivers website content to over 90 countries worldwide, enabling your customers to access your store quickly and reliably, regardless of their geographic location (Source: Search Engine Journal).
In this blog, we will explore Shopify CDN, how it works, its benefits, and customization options.
What is Shopify CDN and How Does It Work?
A Content Delivery Network (CDN) is essential for modern web performance, especially in e-commerce, where speed and reliability directly affect user experience and sales. Shopify CDN, backed by Cloudflare, exemplifies how CDNs can enhance online store performance.
What is a CDN and Why Do You Need One?
Shopify CDN, short for Content Delivery Network, is a network of servers strategically distributed across the globe to deliver website content efficiently. Instead of relying on a single server, a CDN ensures that content is distributed across multiple servers located near users, enabling quicker access and better performance.
With a cache hit rate of 95%, Shopify CDN ensures fast and efficient content delivery, accelerates website speed, improves performance, and enhances user experience by caching static files and delivering content from servers closest to the user’s location. The average response time for Shopify CDN is less than 100 milliseconds (Source: Search Engine Journal).

How Does a CDN Work?
While the technical workings of a CDN are complex, the basic idea is straightforward: deliver web content more efficiently. When a user requests a webpage, the initial request goes to an origin server, which then directs it to the nearest CDN server. This CDN server, or “edge server,” delivers cached content to the user, significantly reducing the distance the data travels and speeding up the load time.
The origin server stores the primary content, including static webpages, images, text, code, software downloads, audio and video files, and dynamic content generated by applications. This content is copied and stored on CDN servers in strategic locations known as points of presence (PoPs). These edge servers handle user requests, ensuring content is delivered from the closest location.
If a CDN server doesn’t have the requested content, it retrieves it from the origin server and caches it for future requests. Intelligent algorithms and machine learning within the CDN software predict content needs, pre-fetch content, and keep the CDN synchronized with any updates on the origin server, thus enhancing performance and reliability.
Shopify CDN automatically minifies and compresses files using Brotli and gzip, reducing the file sizes that browsers need to download. Additionally, requests use HTTP/3 and TLS 1.3, enhancing performance and security.
Typically, asset URLs are formatted as cdn.shopify.com, though images and stylesheets on a storefront might use {shop}.myshopify.com/cdn. This method maximizes connection reuse in the browser, further improving performance.
Do You Compulsorily Need to Use CDN with Shopify?
While not mandatory, using a CDN with Shopify is highly recommended due to the significant performance benefits. Over 99% of Shopify merchants experience improved page load speeds after enabling the CDN (Source: Search Engine Journal). Here’s a breakdown of how Shopify CDN works:
- DNS Server: Converts domain names to IP addresses.
- CDN Server Selection: Selects the optimal server based on user location.
- Content Recovery (Static) from Shopify Store Servers: Static files are retrieved from Shopify’s servers and cached on the CDN servers.
- Delivery to Customer: Delivers cached content from the nearest CDN server swiftly to the end user for a seamless browsing experience.
Shopify CDN creates a positive user experience which can significantly contribute to increased sales on the Shopify Store.

Factors to consider when choosing your Shopify CDN
Choosing the right Content Delivery Network (CDN) for your Shopify store is crucial for ensuring fast and reliable delivery of your online store’s resources. Here are key factors to consider when selecting a Shopify CDN:
- Traffic Volume
For high-traffic stores, a CDN that can handle large volumes of requests and scale accordingly is essential. Shopify’s built-in CDN can handle significant traffic, but if your store experiences extreme spikes, a third-party CDN like Cloudimage or Sirv might be more suitable. - Geographical Reach
A CDN that has a strong global presence can ensure fast load times for users across different regions. Shopify’s CDN is designed to provide fast response times globally, but third-party options can offer more tailored solutions for specific regions. - Features
If you have many images and videos on your site, a CDN that offers advanced optimisation features can significantly improve load times. Cloudimage and Sirv are known for their image and video optimisation capabilities. - Ease of Integration and Use
Ensure that the CDN you choose integrates seamlessly with Shopify, allowing for easy setup and management. Shopify’s built-in CDN is designed to work well with the platform, but third-party options may require more setup.
What does Shopify CDN do to Images?
Shopify CDN automatically optimizes images for faster loading by adjusting their size and format based on the user’s device and browser. This includes:
- Resizing: Adjusting dimensions for optimal display.
- Compression: Reducing file size without quality loss.
- Formats: Converting to modern formats like WebP for better performance.
Storing images on the CDN reduces load times and improves overall website performance.
Short Delays for Images in Your Store
All images in your online store are cached on numerous servers globally, ensuring quick access. When you update your images, Shopify notifies the CDN about the changes by appending version numbers to URLs using the asset_url filter, ensuring the latest images are served. For instance, a version number might look like this: ?v=1384022871.
If you link an image directly without the asset_url filter and then upload a new version, the change might not reflect immediately, potentially taking a day or more.
CSS Syntax to Ensure Automatic Updates
Referencing images directly in CSS results in static URLs, which do not update automatically. To ensure automatic updates, modify your CSS syntax to include the asset_url filter.
For example, change this:
css
Copy code
background: url(bg.gif);
To this:
css
Copy code
background: url({{ ‘bg.gif’ | asset_url }});
Server-Side Rendering
Shopify’s Storefront Renderer (SFR) is dedicated to handling storefront requests as quickly as possible. SFR significantly improves performance for cache misses, where data isn’t found in cache memory and needs retrieval from other sources.
Minification
Shopify automatically minifies CSS and JavaScript files to reduce data download size, resulting in faster load times. Minified files are cached until updated. If the original file is smaller than the minified version, or if it has the extension .min.js or .min.css, Shopify will deliver the original.
Minification might strip out debugger statements. For debugging, temporarily change your file extension to .min.js or .min.css.
Tips for Optimum Use of Shopify CDN
1. Compress Images Before Uploading
Purpose: High-resolution images can significantly slow down your website, leading to longer load times and a poor user experience.
Implementation: Use image compression tools like TinyPNG, ImageOptim, or Shopify’s built-in image compression. These tools reduce the file size without compromising the quality of the images. For Shopify specifically, upload images in formats like JPEG for photos and PNG for graphics to balance quality and performance.
2. Minify CSS and JavaScript Files
Purpose: CSS and JavaScript files that are not minified contain unnecessary spaces, comments, and formatting, which increases their file size.
Implementation: Use tools like UglifyJS for JavaScript and CSSNano for CSS to remove these unnecessary elements. Shopify themes often include options to minify these files, or you can manually minify them before uploading to your store.
3. Enable Brotli Compression
Purpose: Brotli is a modern compression algorithm that can compress files better than older algorithms like Gzip, leading to faster delivery of your assets.
Implementation: Shopify automatically serves Brotli-compressed assets when the browser supports them. To ensure you’re leveraging this, keep your Shopify store updated and verify that your assets are delivered with Brotli compression via browser developer tools.
4. Prioritize and Prefetch Resources
Purpose: Not all resources are needed at the same time. Prioritizing critical resources and prefetching others can improve perceived load times.
Implementation: Use the rel=”preload” attribute to preload critical resources such as CSS, JavaScript, fonts, and images. This ensures these resources are available earlier in the page lifecycle, improving performance. Use the rel=”prefetch” attribute to prefetch resources that will be needed soon, helping to speed up future navigation or resource loading.
5. Caching Rules
Purpose: Proper caching reduces the need to fetch resources from the origin server repeatedly, speeding up load times for returning visitors.
Implementation: Use Cache-Control headers to specify how long browsers and CDN servers should cache your content. For example, static assets like images and CSS can have a longer cache duration (Cache-Control: max-age=31536000), while HTML pages might have a shorter duration to reflect frequent updates.
6. Monitor CDN Performance
Purpose: Regular monitoring helps identify issues such as slow load times, increased error rates, or unoptimized resources.
Implementation: Use tools like Google Analytics, Shopify’s own analytics, or third-party services like Pingdom and GTmetrix to track and analyze your site’s performance. Monitor metrics like Time to First Byte (TTFB), page load times, and error rates.
7. Optimize Shopify Theme and Plugins
Purpose: Poorly coded themes and plugins can introduce bloat, slow down your site, and negatively impact user experience.
Implementation: Regularly review and update your theme and plugins. Remove any unused or redundant plugins. Ensure that all third-party apps and integrations follow performance best practices. Consider using Shopify’s built-in performance tools to audit and optimize your store.
By following these tips, you can ensure that your Shopify store loads quickly, providing a better user experience and potentially improving your SEO and conversion rates.
