JPEG compression is a lossy compression scheme; that is, there is a loss of quality when JPEG compression is applied to an image. So the more compression you apply, the more your image is degraded. Most cameras give you a few different JPEG conversion choices. Some of those choices compress more than others, and therefore degrade your image more than others. Your camera also captures a certain number of pixels. When shooting JPEG images, most cameras give you the choice of shooting at lower pixel counts. So you might be able to save an image that's only half size, for example. This is another way of saving space on your storage card.
