PDF (Portable Document Format) is a file format that has captured all the elements of a printed document as an
electronic image that you can view, navigate, print, or forward to someone else. PDF files are created using Adobe
Acrobat, Acrobat Capture, or similar products. To view and use the files, you need the free Acrobat Reader, which you
can easily download. Once you’ve downloaded the Reader, it will start automatically whenever you want to look at a
PDF file. PDF files are especially useful for documents such as magazine articles, product brochures, or flyers in
which you want to preserve the original graphic appearance online. A PDF file contains one or more page images,
each of which you can zoom in on or out from. You can page forward and backward.
