It can definitely be said that the JPG format offers some truly fantastic features to all its users, such as choosing between the size of the file and the overall quality of the image, thanks to its lossy compression system. It also cleverly exploits the human’s eye natural differentiation in processing between the amount of light, and the color difference that a certain image has. The eye can distinguish the most delicate changes in lighting conditions, in comparison to our perception of differences in color. Because of this we almost see black-and-white in dimmed light, and the JPG quite cleverly utilizes this difference, compressing the color data of the image to a much greater extent than the lighting part.
But in spite of the many versatile capabilities of JPG format, graphic design professionals of all kinds are fully aware of the advantages of converting digital JPG images and other digital drawings to PDF format.
