Sirv PrestaShop image CDN addon

On this page

prestashop logoSpeed up your website with the official Sirv PrestaShop CDN addon.

Faster loading leads immediately to happier users and higher conversions. Making your pages load faster will also improve your SEO. Google ranks faster websites higher, so you'll soon receive more visitors from search engines.

The PrestaShop CDN addon for Sirv is easy to install and starts working immediately. It synchronizes your PrestaShop product images to your Sirv account, then delivers them at the perfect dimensions, in the optimal image format (often WebP). Typical file size is 40-70% smaller than your original images. They're served from the nearest of 20 global CDN servers, for very fast load, anywhere in the world.

Your PrestaShop store can also expect more page views per user and a lower bounce rate. Test your results by comparing your website statistics before and after. Let us know how much difference it makes!

The Sirv addon automatically renames images from meaningless file names such as 1.jpg to keyword rich, meaningful names such as hummingbird-printed-t-shirt.jpg.


1. Download the latest version: Sirv PrestaShop CDN addon (zip).

2. Go to "Modules > Modules Manager" in your PrestaShop admin and click "Upload a module":

Install the PrestaShop CDN

Alternatively, unzip the module to your computer and copy the sirv folder by FTP to the /modules/ directory of your store.

3. Click 'select file' and browse your computer for the file, then click 'Open':

Upload the PrestaShop CDN module zip file

4. Click "Enable":

Enable button for PrestaShop CDN

5. Click "Configure":

Configure button for PrestaShop CDN

6. If you're a new user, click 'No' and create an account. (You'll start on a free 30 day trial - later you can choose a free/paid plan.)

Create your Sirv CDN account

If you're an existing user, go ahead and enter your Sirv email/password:

Connect to your Sirv CDN account

7. Click "Connect Account".

Configure Sirv for the first time

The optimisation settings page looks like this:

Sirv will start working immediately, by copying images from PrestaShop to your Sirv account the first time they are requested.

To accelerate synchronization, perform a sync of your PrestaShop images to Sirv by clicking the "Sync images" button:

Sync library button

A full sync can take minutes or hours, depending how many images are to be synced. Uploads are limited to 2000 files per hour. If you hit the limit, wait to resume sync once the limit is reset. Your current API usage and the reset time is shown on your PrestaShop Sirv settings page. If you would like a higher limit temporarily, please contact us.


Sirv will automatically fetch images when people browse your website. It will resize, optimize and deliver those images from the Sirv CDN or direct from the Sirv primary datacentre in Germany.

Newly found images are typically fetched within 1 second, then cached, ready to server to all future visitors.


The Sirv addon keeps a log of all synced images on PrestaShop. You can clear some or all of this log:

  • Failed - try this method first. It will delete the records of any failed images, so Sirv can try to copy them again.
  • All - use this method if images are not showing as expected. It can resolve images that had a connection problem; were missing when requested; were updated programmatically; were updated by an import/sync tool; or other issues.
PrestaShop CDN cache control

Sirv Media Viewer

Show 360 spins, videos and image zoom on your PDP (product display pages) with Sirv Media Viewer.

You can upload spins, videos and images to your Sirv account and they'll automatically show on the correct product page. The one rule you must follow is to upload your assets to a predictable folder in your Sirv account. The folder should either be named after the product ID or product SKU (also know as the Reference). Find your product ID or SKU here:

PrestaShop product ID and SKU


To upgrade to the latest version of this PrestaShop CDN addon:

  1. Download the latest version (zip).
