Convert MS-Office (Word/Excel/PowerPoint) documents to PDF files via Office Online (and OneDrive).

In some cases, the application on non-Windows machine (e.g. Web Application) uses something (e.g. Apache OpenOffice) to convert files. But, it is difficult to parse the layout of the MS-Office document.
owa2pdf uses the Office Online that is provided by Microsoft, that working is high quality.


Install PhantomJS 1.9+ first.
owa2pdf.js and jquery-2.0.3.min.js must be put on same directory. And, Microsoft account is needed. (see

phantomjs owa2pdf.js -u "" -p "password" -i /path/source.docx -o /path/dest.pdf

The --ignore-ssl-errors=true option may be needed.

phantomjs --ignore-ssl-errors=true owa2pdf.js -u "" -p "password" -i /path/source.docx -o /path/dest.pdf

When the PDF file which is made by Office Online is opened by Adobe Reader, "Print" dialog-box is displayed. It's done by script which was embedded by Office Online. And some other things are embedded by Office Online. removes some things which embedded by Office Online. This is Perl script which needs PDF::API2 and CAM::PDF modules. (e.g. cpanm PDF::API2, cpanm CAM::PDF)

At first, install 2 modules by your favorite installer.

cpanm PDF::API2 CAM::PDF

Then, clean files by

./ /path/dest.pdf


  • owa2pdf is slow.
  • If you have Windows machine and MS-Office, using them is better.
  • If Microsoft releases Office Online API someday, using that is better. (owa2pdf is Web scraping.)
  • Your application might have to retry calling the script. The converting sometimes fails by various causes (e.g. network, MS server, etc.).
  • Your application might have to use the plural accounts, if it converts many files successively.
