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: -What is JPEG Compression? JPEG Compression is the name given to an algorithm developed by the Joint Photographic Experts Group whose purpose is to minimize the file size of photo-graphic image files. JPEG compression is a powerful tool, and with great power comes great responsibility.
