Part 1. What Are JPEG and JPG?

JPEG (Joint Photographic Experts Group) and JPG are both popular image formats used widely across the web and in photography. Technically, they are the same, with JPG being a shortened version of JPEG.

Additionally, there’s a related format known as JPG 2000, which was developed to improve upon the original JPEG standard. JPG 2000 supports better compression, improved image quality, and additional features like transparency. However, it's not as widely adopted as JPEG and JPG.
