Adobe Acrobat was the first software to support Adobe Systems' Portable Document Format (PDF). It is a family of software, some commercial and some free of charge. The Adobe Acrobat Reader program (now just called Adobe Reader) is available as a no-charge download from Adobe's web site, and allows the viewing and printing of PDF files. It is a major component of the Adobe Engagement Platform, and is widely used as a way to present information with a fixed layout similar to a paper publication.
