If you don’t want to include an entire picture, you can crop it to your exact specifications. For example, you might want to zero in on an object in the center of a picture, or remove extra content at the top of a picture.
Select the picture you want to crop.
On the Picture Tools–Format tab, click the Crop button.
Handles surround the picture, enabling you to specify the exact content you want to retain.
Drag the mouse to determine your cropping area.
