Smart cropping tool allows you to automatically cut out the product image from the rest of the image.
For example, you have the following image that contains the shoes you'd like to sell on your website.
As you can see, the image is not centred and there are some other objects (e.g. human's hand, etc.) in the picture. Smart cropping if selected will automatically detect the shoes and make it centralised within the product image. Paired with background removal you can achieve the required quality with just a few settings.
