The .jpg file extension is assigned to image files. Many photographs and Internet graphics are stored in the JPG file format.
JPG files are commonly referred to as JPEG images. JPEG is the acronym for Joint Photographic Experts Group. Many bitmap images are saved in .jpg format in order to compress the files. This makes it easier to transfer or download the files and use them on the Web.
The JPG file format is based on a 24-bit color palette, however, these files tend to drop information when they are decompressed. The higher the rate of compression was when the JPG file was created, the more the quality of the image will be affected when the file is decompressed.
