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.
Detailed explanation-3: -Size of JPEG images can be reduced and compressed which makes this file format suitable for transferring images over the internet because it consumes less bandwidth. A JPEG image can be compressed down to 5% of its original size.
Detailed explanation-4: -What is a JPG? The JPG image file type, typically pronounced jay-peg, was developed by the Joint Photographic Experts Group (JPEG) in 1992. The group realized a need to make large photographic files smaller, so that they could be more easily shared. Some quality is compromised when an image is converted to a JPG.
Detailed explanation-5: -JPEG (Joint Photographic Experts Group image) JPEG is actually a data format for compressed photos, rather than a file type. The JFIF (JPEG File Interchange Format) specification describes the format of the files we think of as “JPEG” images.
