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.
One of the biggest benefits to using lossy compression is that it results in a significantly reduced file size (smaller than lossless compression method), but it also means there is a slight quality loss. This loss in most cases is tiny and can’t even be noticed.
