Sirv CDN is an image hosting, optimization and CDN service to speed up your website. Sirv automatically syncs your images to your Sirv account and then serves them in the most optimal size, format and compression. Used by over 20,000 web stores, Sirv has an easy to install Magento extension, to get started in minutes.

Your images will load faster, in the WebP image format, recommended by Google for website optimization. This helps you get higher conversions, better Google search ranking and less work for your Magento server. Every visitor will receive the most optimally sized image for their browser and screen. It works by copying your images to your Sirv account, where they are processed in on-the-fly and served from one of Sirv’s 20 global datacentres. You don’t need to change any code - just install the extension, connect it to your free-trial Sirv account and Sirv will start working immediately.

Best-Practice Image Optimization

Dramatically faster than traditional hosting, Sirv is the only Magento CDN extension to perform ALL the best-practice image optimizations:

  • Automatic image resizing
  • Automatic image optimization
  • Meta removal
  • Retina delivery
  • Optimal image format delivery (WebP/JPEG/PNG/GIF)
  • HTTP/2 multiplexing
  • Gzip compression
  • HTTPS secure URLs
  • Fast global CDN with 20 edge locations

It’s fully automatic, customizable and fast, with no coding required.

Incredibly Small File Sizes

Sirv optimises images like you wouldn’t believe, without sacrificing image quality. It actually delivers high 85% quality by default, yet your file sizes will be up to 60% smaller. (Get them even smaller by lowering the default quality.)

It’s secret is to deliver the most appropriate image dimensions in the most suitable image format. For Chrome and Opera users, that's usually WebP, the ingeniously optimized image format from Google, supported by Chrome and Opera.

Perfect Image Dimensions

Automatically scaled to the optimal width/height, images are never larger than they need to be. It puts an end to the common Magento problem of serving the nearest size image from a limited set of predefined sizes.

Responsive and lazy loading images, can also be delivered by Sirv. By loading images only when they are needed, it’s another bandwidth saving benefit to accelerate your page load.

The Complete Image CDN

Every possible refinement in image delivery is included in the Sirv extension for Magento. Unlike other extensions which perform one or two tasks, Sirv copies your original images and regenerates them instantly at any size and format. It’s image service that determines the best image based upon each users browser, screen size and screen resolution.

From now on, you’ll always serve the most truly optimal format, at the most optimal dimensions across a fast global CDN. It is the complete image service that your Magento website needs.

How It Works

The Sirv extension for Magento fetches the original product images from your server. All images uploaded through your Magento admin - in the past and in the future - will be synchronized to Sirv the first time they are requested. From then on, images will be processed, optimized, cached and delivered by Sirv.

Images will stay synchronized automatically between your server and Sirv. If you have many images, after installation, you can trigger a full sync of your entire Magento image library.

Speed Up Your Server

Once your image requests are handled by Sirv, your server can concentrate on its primary responsibility - running Magento! Sirv frees-up precious CPU and memory resources for MySQL, PHP and other essential Magento services.

It's a win-win: your server deliver pages faster and your images will load faster from Sirv CDN.

Measure The Improvement

See how much difference the Sirv extension makes. Use the free GTMetrix web page analysis service to measure how much smaller and faster your product pages are.

Perform a GTMetrix test, simulating 3G mobile connection (typical mobile user). Then enable Sirv and test it again. Magento sites typically display an improvement from 10% to 30% faster loading time.

Easy Way To Improve Your SEO

SEO experts explain that faster websites rank higher in search results. It's really that simple. Google first revealed in April 2010 that page load time was an important ranking factor.

About 50% of a typical ecommerce page is images, so by slashing file sizes, pages become dramatically lighter. With all of Sirv's image optimizations, your images could load as fast as the world's leading ecommerce sites. Google loves that and will reward you for it.

Proven And Reliable

Trusted by 10,000+ ecommerce sites, Sirv has become a powerful tool in achieving the most perfectly optimized website.

Processing and delivering more than 1 billion images per day, Sirv fulfils most cached image requests in just 1 millisecond. New images are processed in just 150 milliseconds, then cached. Every user gets an image tailored to their device and nobody has to wait.

A Revolution In Image Management

Pat yourself on the back! By discovering the future in image management, you'll never again need to manually resize, optimize or batch edit your images. Simply upload your original hi-res images and instantly serve them in any size or style.

This revolution frees every web developer from dull, repetitive tasks. But more, it unleashes new creative options. You suddenly have the power to update all images across your website without manual coding or editing. Change styles, add watermarks, add a holiday theme - now you can think different.

Instant Installation

Q. Does it support Magento 2?

Yes. Please download the Sirv extension for Magento 2 from Magento Connect. 

Q. Can I host my other images on Sirv?

Sirv can host any image. It automatically fetches every image uploaded to your Magento admin, including all your product images.

Any other image can also be delivered from Sirv's rapid image hosting service. Images in your Magento theme are probably hard-coded, so you can upload those to your Sirv image hosting account, then update your HTML templates to point at the new image location.

Q. Can I host other file types on Sirv?

Yes. Any file can be delivered rapidly from your Sirv CDN account. JavaScript, CSS, PDF, DOC, XLS, XML... whatever files you need to serve, you can host them in your Sirv account. Reliable and easy file hosting for Magento and all other types of websites and apps.

Q. What's the WebP image format?

WebP is an alternative to JPEG and PNG images, created by Google. Designed to help websites load faster, WebP images are typically 30-70% smaller than an equivalent JPEG/PNG. Chrome and Opera browsers support WebP, so Sirv automatically delivers your images in WebP format to those browsers, helping your pages load even faster (regardless of the original format). Neat, hey?

Q. What’s HTTP/2 multiplexing?

Multiplexing downloads many images in a single HTTP request instead of one request per image. By reducing the number of requests backwards and forwards, it saves considerable time, especially for ecommerce sites with many product images. Sirv automatically uses HTTP/2 multiplexing and serves images over HTTPS by default. You don’t need to lift a finger.

Q. Can I use one Sirv account for multiple Magento sites?

Yes. Your Sirv account supports unlimited websites. Connect any number of Magento or other websites to a single Sirv account. Statistics are aggregated per account, so if you want separate usage stats for a particular site, that site should have its own Sirv account.

Q. Will my images be listed in Google Images?

Yes, your images will be listed as normal. In fact, they are more likely to be listed. For 3 reasons. Firstly, they load faster, which is a very important ranking factor. Secondly, they are better optimized - not poorer quality but in a more optimal image format (Google’s WebP). Finally, before you upload images, you have control over file names, which is a very important ranking factor in Google Images.

Q. Can my images be watermarked?

Sirv can automatically apply any watermark to your images. It supports up to 4 watermarks per image, with an unlimited variety of options. Choose either a text or an image watermark (such as a PNG logo) and set the location, size, opacity and effects. It’s all done by creating what we call a profile in your Sirv account at https://my.sirv.com.
