Images Don't Resize

This article will help perform some checks to determine why images don't resize.

Regenerate Thumbnails

If you already uploaded images to media library, make sure you regenerate thumbnails by following these steps.

Low Server Resources

Resizing and trimming are resource-intensive tasks especially when processed images are large, make sure:

  • In the plugin settings (under WooCommerce menu → Smart Image Resize), select only sizes prefixed by woocommerce_ in the Sizes option.

  • You increase server memory_limit to at least 512M. (Recommended 1024M )

Purge Cache

Make sure you:

  • clear your browser cache

  • purge any caching plugin if present

  • purge CloudFlare cache if present
