Why Optimize Images?

High-quality images in a store allow client to view product details and make a final decision on purchase. The better the quality, the more server space they take and the lower the page load speed. That’s why it’s important to use high-quality image with minimal size. 

Image Optimization add-on allows to reduce the image size without quality loss for any CS-Cart object: product, variation, blog, etc 

Client won’t notice any difference in image quality, pages will load fast, and you’ll save server resource. As a bonus it also positively affects SEO.

How Does it Work?

  • The add-on scans for images and analyzes their quality. 
  • You select 1 of 2 optimization services: resmush.it or shortpixel.com. 
  • You set preferred quality of optimized images and start optimization process.

When operation is complete, you get detailed stats on the results: number of optimized images, saved server space, etc. 

Images, that were not optimized due to some issue are shown separately. You can optimize them once more with a separate feature. Cron-script for auto optimization of new images is also available.


The add-on also works with images used by third-party add-ons.

  • Supported formats for images less than 5 MB - PNG, JPG, GIF, BMP, TIF, for other images - PNG, JPG, GIF.

  • Optimization status of every image is saved into special logs.
  • Search for images that the store does not link to.
  • Ability to sort and search images by size, resolution, name, optimization status.
  • Ability to browse all store images in admin panel at a single page.

This add-on is really great - saving us a lot of time and I love the fact that I can see a report on each individual image. Also great that I can customise the optimization. Great product.
