What Is a PPTX File?
PPTX is the Office Open XML presentation format used by Microsoft PowerPoint since 2007. It stores slides as individual XML files within a ZIP container, supporting text, images, shapes, SmartArt, charts, animations, embedded media, and speaker notes. PPTX is the most widely used presentation format globally and the default export of Google Slides, LibreOffice Impress, and Keynote. Presentations created on Windows render identically on macOS, iOS, and the web.
