| Introduction | The Portable Document Format (PDF) is a file format used to present documents in a manner independent of application software, hardware, and operating systems. Each PDF file encapsulates a complete description of a fixed-layout flat document, including the text, fonts, graphics, and other information needed to display it. | Microsoft Publisher is an entry-level desktop publishing application from Microsoft, differing from Microsoft Word in that the emphasis is placed on page layout and design rather than text composition and proofing. .pub is Microsoft Publisher's proprietary file format. |
| Technical details | The PDF combines three technologies: A subset of the PostScript page description programming language, for generating the layout and graphics. A font-embedding/replacement system to allow fonts to travel with the documents. A structured storage system to bundle these elements and any associated content into a single file, with data compression where appropriate. | LibreOffice has supported Publisher's proprietary file format (.pub) since February 2013. Corel Draw X4 features read-only support. Adobe's PageMaker software saves files with a .pub extension, but the two files are incompatible and unrelated. |
