Convert PPT or PPTX to PDF in Ubuntu

In this article, we cover how to convert PPT or PPTX to PDF in Ubuntu. PPTX is a default file format in Microsoft PowerPoint 2007 or newer versions. Versions prior to 2007 saved the file as PPT. Here, X shows that files are saved in XML format that doesn’t contain macros.

On the other hand, we have PDF (or, Portable Document Format) created by Adobe.

If we want to convert PPT or PPTX to PDF then, we can easily get it done through LibreOffice Impress GUI application. This would work well if there are couple of files we have to convert. But, first install LibreOffice Impress.

Note: Following operations require superuser privileges. In case you don’t have one then, we advise you to contact your System Administrator for assistance.

Convert multiple PPT or PPTX files to PDF through loimpress command

The command-line tool loimpress is made available through LibreOffice Impress package (package installation steps covered above are enough to make the utility available). Use the following syntax to convert the PPT/PPTX files to PDF –
