Ever wondered what a PPTX file is? PPTX files are PowerPoint presentations that were created after 2007, alongside the release of PowerPoint 2007. Microsoft launched the first open XML-based Office documents, including PowerPoint presentations, that were compatible with even more types of software at the time.

Now, this all happened over 15 years ago. In case that you have a file with the outdated ending .ppt on hand and can’t figure out how to save it to PPTX manually, we've got you covered! Simply visit our PDF converters to quickly save it to PDF format, then convert it to PPTX.

How To Convert PPT to PPTX Online

  1. Drag & Drop your file into our PPT converter.

  2. Click on “Export As” and choose “PowerPoint.”

  3. Wait for the tool to turn the PDF back to PowerPoint.

  4. Et voilà! Download your new PPTX presentation.

Will the Content of My File Change?


Nope! When you convert PPT to PPTX, the contents of your file will stay exactly the same. The only difference will be the file ending, as we’ve changed to format from PPT to PPTX. Also, once you've converted your PPT, your slideshows can be viewed on even more software than ever and not just on the outdated PowerPoint 97 version.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 the Microsoft Office suite, which includes PowerPoint, 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. And even if you do, Smallpdf involves less clicking and a very easy-to-use user interface.
