If you transfer an image from your phone to your computer, it will more than likely be in JPG format. JPGs (or JPEGs) are the most common pixel-based image file format. Most monitors will support over 24 million different colors so these pixels can be comprised of A LOT of different possible colors! Because pixels can be so many different possible colors, and there are so many of them in an image, pixel-based images do a great job of capturing photo realism. One image can be comprised of millions of different colored pixels. On the right a small section of balooon blown up where you can see the individual pixels. On the left, you can see the picture of a balloon.
