How to Convert Pptx to Pptby Arn Goldman
Both PPT and PPTX files are presentation files designed by Microsoft for use in its PowerPoint presentation software. PPT (PowerPoint Presentation) files are the simpler of the two; they are editable slideshows that include text, images, videos, sounds and interactive elements. PPTX (PowerPoint Open XML Document) is an updated PPT format based on XML coding that is not readable by versions of PowerPoint prior to the 2007 update. The method of conversion depends on which version of Microsoft Office your computer uses.

Open the PPTX file you wish to convert.
Click the "Save" button.
