JPG (Joint Photographic Experts Group)
JPG is one of the most recognizable, popular, and comprehensible bitmap image formats.This format appeared as a result of the work of the group of photo experts “Joint Photographic Experts Group”. The main task of this group of developers was to develop an optimal image compression algorithm. Today, this problem has been solved successfully. It is used .jpg most often for processing and storing full-color images with realistic images, where brightness and color transitions are inherently present. Also .jpg format is used for storing and transmitting graphic digital content (photos, scan copies, digitized pictures). It is most convenient for placing and transmitting compressed images over the network, because it takes up little space compared to other formats.
ICO (Windows Icon)
An ICO file is an image representing the icon (icon, icon) of a program, file or folder in Microsoft Windows. Icons are used everywhere not only in operating systems, but also on the Internet. The logos of sites displayed on tabs, in the address bar or in the list of bookmarks of a web browser are also ICO images. The file with the logo icon of almost any site has the standard name favicon.ico. ICO files typically store square images ranging in size from 16 by 16 to 256 by 256 pixels. Icons can be black and white or color and, as a rule, have a transparent background. The most common icons are 16x16, 32x32 and 48x48 pixels.
