JPEG uses a 'lossy' compression system and discrete cosine transform technology. Finally, the colors and brightness are coded. First, the photo is transformed into a color space YCbCr, and then it is divided into squares to determine the upper range of the color spectrum. 🔵 The procedure for compressing the digital images in JPG format is carried out in several stages.
