Synch Converter is a free application which converts Word documents stored in SharePoint document libraries to PDF or XPS file formats in real time. Simply, select the document and click an output format button.
Actually we built Synch Converter as a technical exercise in support of sessions that our CEO has been delivering at SharePoint Saturdays all over Australia. We conducted no market research to see if this was a viable commercial product although we certainly think it can be useful in certain scenarios. We basically wanted to see if it could be done and hence our rationale for giving it away for free.
