JPEG (Joint Photographic Experts Group)
Together with the
GIF file format, JPEG is an image file type commonly used on the web. A
JPEG image is a bitmap, and usually has the file suffix ‘.jpg’ or
“.jpeg.” When creating a JPEG image, it is possible to configure the
level of compression to use. As the lowest compression (i.e. the
highest quality) results in the largest file, there is a trade-off
between image quality and file size.
