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.

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.
