We have taken product photos with background. We want to make the photo background to be white, so that we can use it on our website as product photos. Output image size is square, min: 850 x 850 pixel, max: 2000 x 2000 px. We have 200 images that needs become white background. As the images is not going to be used for banner printing, and only for website usage, the images does not need to be precisely cut out.
