JPG = Short for Joint Photographic Experts Group, and pronounced jay-peg.
JPEG is a lossy compression technique for color images. Although it can
reduce files sizes to about 5% of their normal size, some detail is lost in the
compression.
JP2 = JP2 is the file extension for the new image format called JPEG2000
based on the latest image compression technology.
GIF = Pronounced jiff or giff and stands for graphics interchange format, it
is a bit-mapped graphics file format. GIF supports color and various
resolutions. It uses data compression, but it is limited to a 256-color palette.
BMP = The standard bit-mapped graphics format used in the Windows
environment. By convention, graphics files in the BMP format end with a
.BMP extension.
PNG = Short for Portable Network Graphics, is a bit-mapped graphics
format similar to GIF. In fact, PNG was approved as a standard by the World
Wide Web consortium to replace GIF because GIF uses a patented data
compression scheme. In contrast, PNG is patent and license-free.
TIFF = Acronym for Tagged Image File Format, and is one of the most
widely supported file formats for storing bit-mapped images on personal
computers.
TIFF graphics can be any resolution, and they can be black and white, gray-
scaled, or color. Files in TIFF format often end with a .tif extension.
