Typically, there are several reasons why you'd want to resize an image: to make it larger or smaller, or to change the resolution (for example, from 72 to 300 PPI).
If your image has low resolution, be sure not to increase its dimensions any further, which only results in even lower quality resolution. Instead, find a better original image that has more pixel data (resolution).
