Microsoft created the XML Paper Specification format to compete with Adobe's PDF format. Unfortunately, Mac-compatible XPS viewers are not as common as PDF viewers. Adobe Acrobat, Apple Preview, iWork's Pages, OpenOffice and even Microsoft Word for Mac do not support the XPS format. Several options exist to view an XPS file on a Mac system. The options are based on two methods, either reading the XPS file or converting it to a Mac-compatible format such as PDF, HTML or plain text.
Open your preferred Web browser and navigate to the ConvertFiles.com website. This site will convert XPS files to PDF files. You have the option to download the converted file directly or have an e-mail sent to you with the download link. Converted files are available for 24 hours after conversion.
Open your preferred Web browser and navigate to the XPS2PDF.org website. This site also provides free XPS to PDF conversion in a simple interface. There is no e-mail option but the download link for your converted file works for 24 hours.
