JPEG stands for Joint Photographic Experts Group is one of the most popular image formats used for storing and transmitting images on the Internet.
Portable Document Format (PDF) is a file format created by Adobe Systems. Each PDF file encapsulates a complete description of a fixed-layout 2-D document that includes the text, fonts, images, and 2-D vector graphics.

CMYK stands for cyan, magenta, yellow, and black. These are the four colors of ink used in the traditional method of printing, called offset printing. The three colors, plus black, roughly correspond to the primary colors, from which can be mixed colors across the visible spectrum. CMYK is a color mixing system that depends on chemical pigments to achieve the desired hues.

RGB stands for the three primary colors of light - Red, Green, and Blue. RGB can be described as the computer's native colour space for capturing images and displaying them. RGB is not used for printing on paper. The RGB colour model, based on a Cartesian co-ordinate system, is considered as an addictive model in which red, green, and blue are combined in several methods to reproduce all other colors. In the RGB colour model, each colour appears in its primary spectral component of red, green, and blue.
