Method 3: Crop and Resize Images on Mac with Preview Changing the number of pixels a photo has isn't the only way to resize an image. Cropping is also a great way to change the size of a photo because it also allows you to remove parts of an image you don't like. To resize a single picture, simply right-click on the picture, choose services, and select the appropriate service. In order to resize multiple images at once, select the images by clicking the first image, hold down the shift key and select the last image. Next, right-click, choose services, and select the desired service.
