Explanation: 

Detailed explanation-1: -JPEG (/ˈdʒeɪpɛɡ/ JAY-peg) is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality.

Detailed explanation-2: -JPEG format is an excellent example of lossy compression. Files in the . JPEG format are suitable for pictures and photographs with no transparency. They’re great for a site that needs faster loading times, as you can adjust the compression ratios while keeping the right balance.

Detailed explanation-3: -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-4: -Common lossy compression-based image formats are JPEG and MPEG.

Detailed explanation-5: -Zip files are always lossless, and some image formats are lossless (PNG and TIF LZW), but JPG is not lossless. JPG is lossy compression, necessary to be able to do such heroic feats of shrinking the file data so extremely. The process has to take liberties with the data to accomplish it.
