The PDF (Portable Document Format) file format has become ubiquitous in the computing world. PDF is a super format that can embed vector graphics, advanced typography, bitmap graphics, multiple compression technologies, fonts, encryption, interactive elements, and more. It is primarily used for creating documents that display exactly as they looked at creation on any machine. They are great for producing perfectly formatted documents for sharing, or for sending to a professional printer. Print shops often request "photo ready" documents be provided in PDF format.
