However, JPEGs are probably not the best option for images containing text. As a result, if you choose the maximum quality option, your image will most likely be indistinguishable from your original photograph, albeit with a correspondingly larger file size.Īfter compression, JPEGs tend to create artifactsĪs stated in the chart above, JPEGs are great for photographs and images with lots of colors. In most design programs, you can choose the degree of compression you wish to apply to individual images-just be aware that by doing so, you also will alter the image’s quality. JPEGs are also “ lossy,” meaning they retain all color information, but compress file size by selectively discarding data-and that compression can result in a loss of quality. JPEG images (short for Joint Photographic Experts Group) are “full-color images that dedicate at least 24 bits of memory to each pixel, resulting in images that can incorporate 16.8 million colors,” and are frequently referenced by their file extension, JPG.
