The term CONTENTS OF A .JPEG FILE can be summarized as an IMAGE file containing a digital representation of a picture or graphic. A JPEG (Joint Photographic Experts Group) is a type of IMAGE format that is commonly used to store digital photographs and other types of graphics. It is a lossy compression format, meaning that some of the data from the original IMAGE is lost when it is compressed into a JPEG file. The contents of a JPEG file are typically a digital representation of a picture or graphic, such as a photograph, logo, or drawing.
