PDF (Portable Document Format)
PDF (Portable Document Format), is not just a well-known and convenient format, but the only one that has been standard since 2008. It was developed by the Adobe Systems team. The developers of the format set themselves the task of creating such a format for displaying the document so that the document opens and looks the same on any device. The PDF format is used for storing and transmitting text and graphic information on the network, for example, for transferring letterhead to the printing industry or posting a questionnaire on the website. Great for demonstrating developments: easy to show, edit - difficult. This complicates the theft of intellectual property. Well, the ideas of a "paperless office" are received with a bang by everyone who thinks about ecology on the planet.
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.
