GIF - Standard
computer file format for graphic images. GIF files use data compression to
reduce the file size. The original version of the format was developed by
CompuServe in 1987. The current version supports animated GIFs (a graphics
image that moves).
According to Britannica Encyclopedia, GIF in
full graphics interchange format,digital file format devised in
1987 by the Internet service provider CompuServe
as a means of reducing the size of images and short animations. Because GIF is
a lossless data compression format,
meaning that no information is lost in the compression, it quickly became a
popular format for transmitting and storing graphic files.

JPEG - named after its creator the
Joint Photographic Expert Group - (seen most often with the .jpg extension)
is a commonly used method of lossy compression for digital photography (i.e.
images). The degree of compression can be adjusted, allowing a selectable
tradeoff between storage size and image quality. JPEG typically achieves 10:1
compression with little perceptible loss in image quality, and is the file type
most often produced in digital photography.
JPEG compression is
used in a number of image file formats. JPEG/Exif is the most common
image format used by digital cameras and other photographic image capture
devices; along with JPEG/JFIF, it is the most common format for
storing and transmitting photographic images on the World Wide Web.These
format variations are often not distinguished, and are simply called JPEG.
The term
"JPEG" is an acronym for the Joint Photographic Experts Group,
which created the standard. The MIME media type for JPEG is image/jpeg (defined
in RFC 1341), except in Internet Explorer, which provides a MIME type
of image/pjpeg when uploading JPEG images. JPEG/JFIF supports
a maximum image size of 65535×65535
