Saving Word DOCX files as PDF [closed]

Question

I'm using openxml to create Word DOCX files. I'd like to save these documents once they are created as PDF files. Is there a way I can do this in openxml? I assume the answer is no. If it is no, is there a recommended library or tool I can use to save / print DOCX files as PDF (programatically, in .NET)? I looked at sharpPDF (PDFSharp), and it seems this library is only for generating PDFs from scratch, not saving DOCX as PDF.

Can I somehow Print to an installed PDF printer, either Cute PDF or the PDF printer built in to Windows 7 in a fully automated fashion?

Update: Looking for free with non-viral license, and preferably doesn't require additional installations.

Answer 1

You could do this with Word automation. You need to have word installed.

var TheDocument = TheWordApp.Documents.Open(docName);

TheDocument.ExportAsFixedFormat(
            docName.Replace(".docx", ".pdf"),
            Word.WdExportFormat.wdExportFormatPDF, 
            OptimizeFor: Word.WdExportOptimizeFor.wdExportOptimizeForOnScreen, 
            BitmapMissingFonts: true, DocStructureTags: false);

((Word._Document)TheDocument).Close();

Answer 2

To get from DocX -> PDF you need something that can render a DocX file and provides a PDF export/save capability. Needless to say, there aren't that many tools that can render DocX (Word, OpenOffice/LibreOffice and some other licensed products mentioned below). Depending on your runtime limitations/requirements, you could try:

1. to use MS Automation to get Word to load the docx and save as PDF.
2. tools that sit on top of OpenOffice (JODConverter/Docmosis) to do the conversion.
3. try embedding other document libraries (Aspose, Windward)

I'm not sure about the auto print requirement sorry.

I've successfully used the Aspose suite of tools for this in the past: https://stackoverflow.com/a/5513946/54762. It's not free, but you can demo it before you buy it.
