Sirv PrestaShop image CDN addon

On this page

Speed 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 with your Sirv account and delivers them at the perfect dimensions and optimal image format (often WebP), typically with 40-70% smaller file size. Images are then 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. Share with us how much improvement you experience.

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 many minutes, even hours, depending on the number of images in your library and the speed of your server's network connection. It typically syncs 50-200 images per minute.

Sync more files

You can get even more benefit from your Sirv CDN account by activating auto-fetch. Then go to the Performance page within the Advanced Parameters section of PrestaShop and set 'Media server #1' to your Sirv domain. Files such as theme image, icons and any undetected JS & CSS files will also be served by Sirv.


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 record of all synced images. In rare circumstances, the records might become out of date. If you see old images or missing images, use one of the cache clearing options:

  • 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 still not showing as expected. It can resolve images that had a connection problem; were missing when requested; were updated programmaticaly; were updated by an import/sync tool; or other issues.
  • Master - only use this if you have deleted a large number of images from your server and want to delete them from Sirv. All master images will be re-synced, which can take a long time for large image libraries. This will cause a small delay (typically 1-3 seconds) for the first person to request each image.
