Best-Practice Image Optimization

Dramatically faster than traditional hosting, Sirv is the only Magento CDN extension to perform ALL the best-practice image optimizations. It’s fully automatic, customizable and fast, with no coding required.

  • 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


Incredibly Small File Sizes

Sirv optimizes images like you wouldn’t believe, without sacrificing image quality. It delivers high quality by default (80%), yet your file sizes will be up to 60% smaller. It cleverly serves the most appropriate image dimensions in the best 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 Only Complete Image CDN Solution

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

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

How It Works

The Sirv extension for Magento fetches your original product images from your server. Images are automatically fetched the first time they are requested by a browser. They’re then optimized, cached and delivered by Sirv. If you have many images and want to speed things up, click the button to start full sync of your Magento image library.

Images will stay in sync automatically between your server and Sirv. New images will be fetched, deleted images will be removed from Sirv.


Speed Up Your Own Server

Once your images 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 situation. Your server will deliver web pages faster and your images will load considerably faster from Sirv's powerful CDN.


Measure Improvement

See for yourself just how much difference the Sirv extension makes. Use the free GTMetrix service to measure the file size and loading speed for one of your product pages. Set GTMetrix to load the test from Chrome on a 3G mobile connection, to simulate a typical mobile user. Compare the different results with the Sirv extension enabled and disabled. Magento sites typically show a 10% to 30% faster loading time.


Improve SEO Without Lifting A Finger

SEO experts frequently remind us that faster websites rank higher in search results. It really is that simple. When Google revealed in April 2010 the importance of page load time as a ranking factor, a spotlight was shone on this valuable organic search factor. Over 50% of a typical eCommerce page are images, so by slashing image file sizes, pages become dramatically lighter. With all Sirv's other CDN optimizations, your images will load as fast or even faster than the world's leading eCommerce sites. Google will reward you for that.


Proven & Reliable

Trusted by more than 10,000 eCommerce sites, Sirv has become an essential tool in achieving the ultimate goal - the most perfectly optimized website achievable. Processing and delivering more than 1 billion images per day, Sirv fulfills 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.


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. Just 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

In literally 5 minutes, you too can be delivering your images from this highly optimized Magento CDN. Install the extension, create a free Sirv account and link them together. That's all.

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 20-50% smaller than an equivalent JPEG/PNG. Chrome and Opera will receive WebP images from Sirv, helping your pages load even faster (regardless of their original format). Neat, hey?

Q. What’s HTTP/2 multiplexing?

Multiplexing fetches many images in a single HTTP request instead of one request per image. By reducing the number of requests backward and forwards, it saves considerable time, especially for eCommerce sites with many product images. Sirv uses HTTP/2 multiplexing and 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, WordPress, Drupal or other websites to a single Sirv account. Statistics are aggregated per account, so if you want separate usage stats per site, create an additional Sirv account.

Q. Will my images be listed in Google Images?

Yes, your images will continue to be listed as normal. In fact, they are more likely to be listed if you use Sirv. For 3 reasons. Firstly, they load faster, which is a very important ranking factor. Secondly, they are better optimized - high quality yet in a more optimal image format (WebP). You also have control over image file names - another important ranking factor in Google Images.

Q. Can my images be watermarked?

Sirv can automatically apply watermarks to your images. Add up to 4 watermarks per image using either text and/or image watermarks (such as a PNG logo). Choose the location, size, opacity, and effects with what we call a profile in your Sirv account at https://my.sirv.com.
