Ever wondered what a PPTX file is? PPTX files are PowerPoint presentations that were released after 2007, alongside the release of PowerPoint 2007. This all happened at the same time as Microsoft’s launch of the first open XML-based Office documents that included PowerPoint presentations that were compatible with even more types of software at the time.

So, if you have a PPT file on hand and can’t figure out how to save it to PPTX manually, we've got you covered! Simply hop onto our PDF converters to quickly save it to PDF format, then change it up to PPTX.

How To Convert PPT to PPTX Online

  1. Go to our PPT converter and drag your PPT file inside the tool.

  2. Download the converted file in PDF format.

  3. Next, go to our PDF to PPT tool.

  4. Drag the new PDF into the toolbox and wait for it to convert.

  5. Et voilà! Download your new PPTX presentation.

First convert the PPT to PDF, and then to PPTX.

Will the Content of My File Change?

 

Nope! Once you convert PPT to PPTX, the contents of your file will stay exactly the same as the original and only the formatting will change a little. Also, once you've converted your PPT, your slideshows can be viewed on even more software than ever and not just on the outdated PowerPoint 97 version.

Of course, if you have Microsoft PowerPoint itself, you can always open the PPT to save it to PPTX manually. But we know the hefty price tag of the software means that not everyone will want to pay for it.
