Hello,

The product images are controlled by WooCommerce and our theme doesn’t influence them. WooCommerce provides settings for images that you can find under Appearance >> Customize >> WooCommerce >> Product Images.

You can set the thumbnail width and crop according to your needs.

There is no such quality reducer function in our theme.

Best Regards.
