Detailed explanation-1: -JPEG, which stands for Joint Photographic Experts Groups is a “lossy” format meaning that the image is compressed to make a smaller file.
Detailed explanation-2: -Both PNG and TIFF files benefit from lossless compression, meaning that no matter how often you save, open, or resize them, they’ll maintain their quality.
Detailed explanation-3: -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.
Detailed explanation-4: -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.
