How to open PPTX files

Did your computer fail to open a PPTX file? We explain what PPTX files are and recommend software that we know can open or convert your files.

What is a PPTX file?

PPTX files are PowerPoint Open XML Format presentation files, which you can read more about below.

The PPTX file extension indicates to your device which app can open the file. However, different apps may use the same file extension for different types of data. So a PPTX opener may not be able to open all kinds of PPTX files. In this case, though, we only know of one specific use.

PowerPoint Open XML Format presentation

The PPTX file extension is given to Microsoft PowerPoint files created in PowerPoint versions 2007 and later. Microsoft PowerPoint is a presentation software that allows users to create slide shows containing pictures, text, music, and video. The PowerPoint program is included in the Microsoft Office Suite.

Earlier versions of Microsoft PowerPoint create files using the .ppt file extension. Later versions of PowerPoint assign the .pptx extension because they use the Open XML format. This format allows PowerPoint files to be compressed into smaller sizes, making it easier to distribute the files online and taking up less drive space on a user's computer.
