This invention caused the paper-to-digital revolution, because the main purpose of inventing PDF was to make document look the same way as the original version on any computer or device.
Technical Details: Every PDF file has a structure with fixed formatting and information about fonts and graphic elements on each page of a document. PDF document may contain different types of elements, such as buttons, hyperlinks, bookmarks, or annotations.
