Both Mac and Windows have basic image editors which you can use to modify images, as discussed below.
Resizing (Back to top)
The free site ?http://www.picnik.com provides easy access to the most common photo editing tools, making it extremely easy to Resize, Crop, Color and otherwise edit images.

Cropping is cutting off parts of an image to fit pre-defined dimensions.The following table shows a full image and a cropped version.
