PDF - Portable Document Format - currently it is a standard format for electronic documents, for which it was originally developed by programmers at Adobe Systems. They set a goal to optimize the way they store and display text documents and printing publications. The new PDF format did not immediately gain current popularity, it took time to adopt a new standard.
PDF is a cross-platform format used for storing scanned paper documents: books, magazines, drawings. Many of the common books and documents that go electronically are in PDF format. PDF files may contain text, images, tables, forms, annotations, and other data. It is noteworthy that the display of the document does not depend on the platform - on Windows or Mac OS, the documents will look the same, as well as when printing.
The most popular program for viewing this format is Adobe Acrobat Reader, it is free. Some browsers like Google Chrome provides support for this format by default. For editing you will need a text editor with subsequent conversion to PDF.

The popular PDF format often stores various documents, instructions, e-books, etc. This format has its advantages: on any computer, in any operating system, the file looks the same. Sometimes the size of a pdf file is several kilobytes, but more often the size can reach several tens of megabytes due to the large number of pages with heavy graphic elements. If you have a large PDF document and cannot be sent by mail due to attachment size restrictions or it does not fit on a USB flash drive, you can try to reduce its size. Graphic-rich PDFs look nice, but sending them by e-mail is a pain because of the large size of such documents. Two PDF documents that look identical can vary significantly in size. It depends on the resolution of the images it contains, the fonts and the compression mechanism of the document itself. Compressing PDF files is not as difficult as it might seem at first glance. There are a number of programs with which it is possible to perform these actions quickly and easily.
