I need to convert a .pptx file to .pdf but I don't own a copy of Microsoft Office. I tried OpenOffice, but my document was badly flawed in OpenOffice and so much was lost.

Is there a tool out there to do this conversion without having to actually go and buy a copy of Microsoft Office?

    Would you be willing to use a web app?

    When using a web app be sure to read ALL the licence information - it turns out that, according to some high priced lawyers, by uploading to some you are granting them copyright and/or publishing your information so they should not be used for proprietary/sensitive information. Recently had a warning about this at work. Same for some online translation & photo tools. Jul 24, 2014 at 5:09

Microsoft Power Point Viewer can open any powerpoint (post 1997), including .pptx. It can be downloaded for free.

If you right click you can select Print. if you have a PDF printer installed, then you print to PDF and you are done.

There are many good free PDF printers out there. You can start another question if you have particular intrest in them. I've use PDFCreator in the past it is quiet good. I tested this just then using pdf24, and it worked fine.


Online Solution. No Software Required.

Try Google Drive.

Upload your .ppt file to Google Drive. Open the file and from the File Menu, Select Download as where you will find the option of PDF Document. I use this feature a lot.


You should try Kingsoft Office. It is known as being more friendly with Office formats than OpenOffice/LibreOffice.

Another (non free) program that can do this is Smart Draw. It's rather expensive and I haven't used it in a while but it always had good quality.


If you are looking for an easy online tool that has no registration or download required, you can try online2pdf. I have used them in the past with no problems whatsoever. I have never found my information to be exposed or abused.

It can convert a variety of document and picture formats to PDF, including pptx. You can upload multiple files at a time to put a bunch of files into a single PDF document.

To convert, simply upload your document you wish to convert, change some settings around if you wish to do so, then click on convert.

The only restriction is that files must be under 50MB and you can only process 100MB of files during one conversion.
