Detailed explanation-1: -JPEG uses lossy compression algorithm. GIF uses lossless compression algorithm. JPEG image may lose some image data causing quality loss.
Detailed explanation-2: -The JPEG image file, commonly used for photographs and other complex still images on the web with no transparency, is generally compressed using lossy compression. Using JPEG compression, the creator can decide how much loss to introduce, and how much of a trade-off is acceptable between file size and image quality.
Detailed explanation-3: -The most common lossy image formats are JPEG and GIF. However, our human eyes do not notice the difference between JPEG, GIF, PNG, or other formats. Images are great candidates for lossy compression because of the way our eyes work. Our eyes have a different sensitivity to different colors.
