JPEG stands for Joint Photographic Experts Group, the original name of the committee that wrote the standardized JPEG image compression mechanism. JPEG achieves great compression of images by discarding information that the human eye cannot see; thus it is a lossy compression method.
JPEG compression can be adjusted so that the images take up more or less space in their storage; however, the smaller the space they take, the lower the quality of the images. Photozig Albums uses 90% quality JPEG images to achieve optimum balance between quality and space savings.
