JPEG (Joint Photographic Experts Group) is a way to store images by compressing digital images, especially for natural or real scenes. However, it is not suite for online drawings and cartoons. When compressing images, some information will be lost. But human eyes won’t find the inconspicuous difference.  

WMF (Windows Metafile) is a 16- bit graphic format appearing on MS Windows systems. It became commonly used since the wide use of graphics formats, like GIF and JPEG. Windows graphic layers GDI can execute the WMF format to store image. It contains the functions of compressing files, editing images and so on. Generally, a whole image is stored as a sequence of separated parts. The images are often rough and can be edited only in Microsoft Office.

WMZ is Compressed Windows Metafile.

BMP (Bitmap) is very popular nowadays due to the common use of Windows. That is because BMP is the standard format used by Windows for saving image files. It contains more image information than the JPEG, and there is almost no compression of images. So it takes a larger disk space. Presently, 24 bits per pixel BMP files are the most common in all the 1, 4, 8, 15, 24, 32, 64 bits per pixel BMP files.

Other image format definition:

RAW is a kind of file that contains all information about the image after its original image file has been produced from sensor. Users could deal with images output from Camera in the format by using much image-processing software on PC. Contrasted with TIFF and JPEG, RAW doesn’t only save storing space but assure image quality and color. Besides, with 12bit data, details could be squeezed from either high light or dark regions of Raw files, which is out of the ability of both JPEG and TIFF files.
