To crop a photo or graphic open on your screen, you must first select the area of the image you want to keep.ĭrag the mouse cursor over the part of the photo you want, which creates a dotted line around the area.
You can crop photos, graphics and PDF files right in Preview, the Mac’s built-in image-editing and viewer program. How do you crop an image in the Mac Preview program? I don’t see a cropping icon in the tool bar.
