There are a few ways to crop an image to a shape in Illustrator. The first way is to use the selection tool, which is located at the bottom of the screen. To select a part of the image, click on it and then drag it up or down. The second way is to use the arrow keys to move the selection around. The third way is to use the command key (cmd) to select all of the pixels in an image and then press cmd+v (or ctrl+v).
