The JPEG format, which stands for , was developed to solve the problem of large digital image file sizes. Before its adoption in the early 1990s, storing high-quality photographs required immense storage space, which was a scarce resource on early personal computers and the nascent internet. By using a method called lossy compression , JPEGs discard data that the human eye is less likely to notice, such as subtle variations in color, while keeping the essential details of a photograph intact.
