JPEG, JPE, JPG
Best for full-color photographs Highly compressed Encoded in full color
Lossy compression Loses quality as you edit and save JPG most universally used lossy format

GIF Good for fewer colors, such as a logo Indexed format – uses up to 256 colors
o 256 = 28 referred to as 8-bit coloro Advantages
o Transparencyo Animation

PNG Two modes
Indexed Full color Lossless compression
Full and partial transparency Doesn’t support animation
