PPTX is the modern Microsoft PowerPoint presentation format, based on the OOXML standard. PPTX files contain slides with text, images, shapes, charts, SmartArt, tables, video, audio, animations, transitions, and speaker notes. The format supports slide masters and layouts for consistent design, embedded fonts, hyperlinks, and action buttons. PPTX presentations can contain hundreds of slides and are used for business presentations, educational lectures, conference talks, and marketing materials. PPTX is supported by Microsoft PowerPoint, Google Slides, LibreOffice Impress, Apple Keynote, and Canva. Converting PPTX to PDF creates a universally viewable, non-editable version ideal for distribution.
