Explanation:
Detailed explanation-1: -Common lossy compression-based image formats are JPEG and MPEG.
Detailed explanation-2: -Lossy compression refers to compression in which some of the data from the original file (JPEG) is lost. The process is irreversible, once you convert to lossy, you can’t go back. And the more you compress it, the more degradation occurs. JPEGs and GIFs are both lossy image formats.
