#REDIRECT [[Open XML Paper Specification]] {{R from merge}}
This is a comparison of the [[Open XML Paper Specification|OpenXPS]] [[document file format]] with the [[Portable Document Format|PDF]] [[file format]]. Both file format standards are essentially [[Container format (digital)|containers]] for representing [[Content (media and publishing)|digital content]] in a paper-like fashion.<ref>http://www.microsoft-watch.com/content/business_applications/pdf_and_xps_when_acronyms_compete.html</ref>
==Design aims==
The differences between Open XML Paper Specification (OpenXPS) and the Portable Document Format (PDF) can be traced to their [[Virtual Heritage|heritage]] and the manner of their development, as they have different design goals and different groups providing input.
The different goals in the development of OpenXPS and PDF resulted in different principles and design tradeoffs between the file formats.
