What is a JPG in ICT?

A JPG, or JPEG (Joint Photographic Experts Group), is a commonly used image file format in information and communication technology (ICT) that employs lossy compression to reduce file size while maintaining acceptable image quality. It is widely used for storing and transmitting photographic images on the web due to its efficient compression capabilities, which balance image quality and file size. JPG files support a range of color depths and are popular for applications such as digital Photography and online image sharing. However, repeated saving of a JPG can lead to degradation in quality due to its lossy nature.
