What is a PDF?

PDF stands for Portable Document Format. Saving a document in this format ensures that it will look the same when viewed on another computer as it did on the original computer when created. It will also have a MUCH smaller file size, hence the “portable” part of the name. PDF is used for representing two-dimensional documents in a device-independent and display resolution-independent fixed-layout document format. Each PDF file encapsulates a complete description of a 2-D document (and, with Acrobat 3-D, embedded 3-D documents) that includes the text, fonts, images, and 2-D vector graphics that compose the document.
If you want to view a .pdf file, you’ll need the free Adobe Acrobat Reader, or even the Foxit Reader. Of course, the free versions of both of these programs will only allow you to read the document, not edit or create a .pdf of your own. For that, you will need full paid versions. Also, for a Mac user, there is a .pdf viewer built right in, so you don’t have to download anything at all!
