JPEG – is a popular graphic format, which is characterized by a high degree of compression, which leads to a decrease in image quality. It uses the technology of encoding of smooth color renditions, providing the ability to reduce the amount of data frequently during the recording of the image. Because of the small size it is requested by the owners of websites, allowing you to save the traffic effectively. It is also frequently used in memory cards of digital video cameras. The JPEG algorithm is optimally suitable for compressing photographs and pictures, in which realistic scenes with little contrast of colors are present. It is not recommended to use this format for compression of drawings and various kinds of graphics, since a strong contrast between a number of closely located pixels provokes the appearance of visible artifacts.
The procedure for compressing the digital images in JPEG format is carried out in several stages. First, the photo is transformed into a color space YCbCr, then it is divided into squares to determine the upper range of the color spectrum. Finally, the colors and brightness are coded. JPEG uses a "lossy" compression system and discrete cosine transform technology. The format acts simultaneously as the standard of ISO and the International Telecommunication Union. The file compression ratio is in the range from 10:1 to 100:1. In this case, the reduction in image quality can vary from insignificant to substantial.

Microsoft icon file
ICO – is a special format for displaying icons, shortcuts, icons in Windows OS. It represents two bitmaps. The first is the image mask, and the second is the icon displayed on the mask. It is used to connect a picture with an OS file. Users of devices with operating systems from Microsoft can edit the ICO files to create special icons. It can be converted to files with popular JEPG and PNG extensions. Saving files in ICO is used when developing graphics in the form of indicators, icons and similar graphical elements. They are used as an icon and site logo. They are opened by any application for viewing images and special programs like ACDSee or Axialis IconWorkshop.
The .ico extension is used from the very first versions of Windows OS, gradually adding in size and maximum number of supported hues. For example, the "seven" is able to support icons up to 256x256 pixels in 32 bits. To ensure the compatibility with earlier versions of Windows, it is better to use eight-bit icon versions.
