Format Details
PPSX
PPSX is the modern Open XML-based equivalent of the legacy PPS format, introduced with Office 2007. Like PPS, a PPSX file opens directly in slideshow mode, bypassing the editing interface, which is ideal for distributing polished presentations. PPSX uses the same compressed XML format as PPTX but with the presentation-mode-first file association behavior.
PPTX
PPTX is the default Microsoft PowerPoint presentation format since Office 2007, based on the Open XML standard and standardized by ISO/IEC. It stores slides, animations, transitions, speaker notes, embedded media, and themes in a compressed ZIP package of XML files. PPTX is the dominant presentation format in business and education worldwide, natively supported by Google Slides, LibreOffice Impress, Apple Keynote, and all modern presentation tools.
