Give a shape and every image is cropped to the largest box of that shape, anchored at the centre, the top, the bottom or a side, so a folder of product shots or thumbnails comes out uniform. Pixel mode takes exact coordinates for screenshots that always need the same corner cut off.
For a single picture where the box has to be just so, open it in the editor: the crop tool there has the same aspect presets, draggable handles, a rule-of-thirds grid and numeric fields.
