JPG files, also known as JPEG files, are a common file format for digital photos and other digital graphics. When JPG files are saved, they use "lossy" compression, meaning image quality is lost as file size decreases. JPEG stands for Joint Photographic Experts Group, the committee that created the file type.

JPG files have the file extension .jpg or .jpeg. They are the most common file type for images taken with digital cameras, and widely used for photos and other graphics used on websites.

Unlike GIF files, which show significant loss in photo image quality, JPGs allow for some degree of file size reduction without losing too much image quality. However, as file sizes get very low, JPG images will become "muddy." When saving photos and other images as JPG files for the web, email and other uses, you must decide on this tradeoff between quality and file size.
