Adobe Acrobat Reader Online files are created in PDF file format and require Adobe Acrobat Viewer (version 5.0 or above) to view or print. They are produced this way to keep the online display as close as possible to the printed version.
Adobe Acrobat® ReaderTM is free, and freely distributable, software that lets you view and print Adobe Portable Document Format (PDF) files.
You can download the free reader directly from Adobe.
