The JPEG image format is the most common format for storing digital photos. It uses lossy compression to reduce the file size. The compression is typically not noticeable unless high amounts of compression are used.

Most digital cameras save images as JPEG files. Therefore, when you import pictures from a digital camera, they are usually imported as JPEG images. Most image-editing programs can also export digital images to a JPEG format.

JPEG images usually have a .JPG extension.
