About formats

PPS (PowerPoint Slideshow) is a binary presentation format from Microsoft that functions identically to PPT with one behavioral difference: double-clicking a PPS file launches it directly in slideshow (full-screen) mode rather than opening the editing interface. The format uses the same OLE2 compound document structure as PPT, storing slides, text, images, animations, transitions, speaker notes, and embedded objects in binary streams. PPS files are typically produced by saving a finished PPT presentation in slideshow format, signaling that the content is intended for viewing rather than editing — though the file can still be opened for editing through PowerPoint's File menu. The format gained widespread use in corporate environments for distributing ready-to-present slide decks, training materials, kiosk displays, and self-running presentations. One advantage is presentation-ready behavior — recipients can launch a PPS file and immediately begin presenting without navigating editing tools, reducing the chance of accidentally modifying content or revealing speaker notes. The auto-play capability is another strength for unattended scenarios: combined with automatic timing and looping features, PPS files power information kiosks, digital signage, and lobby displays that run continuously without operator interaction. While the newer PPSX format has superseded PPS for current workflows, the binary slideshow format remains encountered in archived corporate materials and legacy presentation libraries.
Developer: Microsoft
Initial release: 1995
PPTX is the default file format for Microsoft PowerPoint presentations since Office 2007, based on the Office Open XML (OOXML) standard published as ECMA-376 and later adopted as ISO/IEC 29500. A PPTX file is a ZIP archive containing XML documents that describe slide content, layouts, themes, relationships, and metadata in a structured, human-inspectable hierarchy. Each slide, slide layout, and slide master is stored as a separate XML part, with media assets (images, audio, video) and embedded objects kept in dedicated directories within the package. The XML foundation enables programmatic creation and manipulation of presentations using standard XML tools and libraries — developers can generate, modify, or extract content from PPTX files without requiring PowerPoint itself. One significant advantage is openness and interoperability: the fully documented OOXML specification allows any software to read and write PPTX files, and the format is supported by LibreOffice Impress, Google Slides, Apple Keynote, and numerous other tools. Built-in ZIP compression is another practical strength — PPTX files are typically 50-75% smaller than equivalent PPT files, reducing storage and transfer costs. The format supports all modern PowerPoint features including SmartArt, 3D models, morph transitions, embedded fonts, accessibility metadata, and co-authoring capabilities. PPTX has become the standard interchange format for presentation content worldwide.
