The most used file format for storing digital photos or images on the Internet is JPEG, also known as JPG. JPEG stands for Joint Photographic Experts Group JFIF image format and it uses a lossy image compression algorithm. As the name implies, a lossy compression algorithm is an algorithm that sacrifices image data for a smaller file size. However the resulting picture will often be undistinguishable from the original one by the human eye.
