We understand that some entities have unique circumstances, usually due to regulatory restrictions, and cannot rely on publicly hosted image processing services. We provide only image processing and delivery, so if you’re looking for cloud storage and sharing files, we’re probably not the right choice. To crop an image, you specify four parameters – the origin x and y (which defines the top left of the crop rectangle) and the dimensions w and h (which define the size of the rectangle).Starting Price: $ 15 Per month -
