You have 3 options to resize your image. First is scale which changes image's height or width by scaling image. No image part is lost. All edges and corners of image are still visible on the new image. But they are bigger or smaller. Second options is to crop them which cuts and removes the outer area of image to resize it. Third option is to use fit. You can prefer fit to fit image into a frame. It works like scale option. But it forces to keep width-to-height ratio of the original image.
