What is PPTX File Format?

PPTX files are presentation files created by Microsoft PowerPoint and other presentation apps. Unlike the older binary PPT format, PPTX is based on Office Open XML. A presentation contains slides that can include text, images, formatting, animations, and other media. Slides are shown to an audience as slide shows with custom presentation settings.
