Talk given at the BOBCATSSS 2015 conference - http://www.bobcatsss2015.com/. The purpose of this paper was to point out the role of pictograms in online world because they are getting more and more used by web designers. We conducted research in which we compared packages of icons and their most important characteristics. It will be discussed whether so many different icons with the same meaning which differ from each other only in small proportions should be used, or should they be universal.
