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. How JPEG Compression Works The compression process involves several technical steps:

The image is converted from RGB (Red, Green, Blue) to YCbCr, which separates brightness (luminance) from color (chrominance). IMG_20230302_113253_198.jpg

Because the human eye is more sensitive to changes in brightness than color, some color information is discarded without significantly affecting the perceived quality. The JPEG format, which stands for , was
