About formats

POT (PowerPoint Template) is the binary template format for Microsoft PowerPoint, using the same OLE2 compound document structure as PPT files. A POT file contains a complete presentation structure — slide masters, color schemes, font definitions, placeholder layouts, background designs, and default formatting — that serves as a reusable foundation for new presentations with consistent branding. When a user creates a new presentation from a POT template, PowerPoint generates a fresh untitled document pre-populated with the template's design elements while leaving the original file unmodified. The format supports all visual features available in PPT including custom slide layouts, embedded graphics, animations, transition presets, and action buttons on master slides. POT templates became central to corporate identity management in organizations that standardized their visual communications through PowerPoint, ensuring every department produced presentations with approved logos, color palettes, fonts, and layouts. One advantage is brand consistency at scale — distributing a POT file across an organization guarantees that all new presentations inherit the correct visual identity without requiring each author to manually replicate design elements. Rapid document creation is another strength: presenters start with professional layouts and focus on content rather than design, reducing preparation time. While the XML-based POTX format has replaced POT for modern workflows, the binary template format remains in use where compatibility with PowerPoint 97-2003 is required.

PPSX (PowerPoint Slideshow XML) is the Open XML counterpart to the legacy PPS format, introduced by Microsoft with Office 2007. Like PPTX, a PPSX file is a ZIP archive containing XML parts that describe slides, layouts, themes, and media assets according to the Office Open XML specification. The distinguishing characteristic is behavioral: opening a PPSX file launches the presentation directly in full-screen slideshow mode, bypassing the editing environment. This makes PPSX the preferred format for distributing finalized presentations where the audience should experience the content as a seamless visual narrative without exposure to the editing interface, slide sorter, or speaker notes panel. PPSX files support every visual feature available in PPTX including transitions, animations, embedded video and audio, hyperlinks, SmartArt, charts, and custom slide timings. One advantage is streamlined delivery — a PPSX file attached to an email or shared via a link opens as a polished presentation with a single click, requiring no instruction to the recipient. The XML-based foundation provides another benefit: PPSX files are typically much smaller than equivalent PPS files due to built-in ZIP compression, and their contents can be inspected or modified programmatically using standard XML tools. The format is supported for playback in PowerPoint, LibreOffice Impress, Google Slides (after upload), and various mobile presentation apps, ensuring broad cross-platform reach for distributed slide decks.
