PPTX
PPTX is the default file format for Microsoft PowerPoint presentations introduced in PowerPoint 2007. It is part of the Office Open XML (OOXML) family and stores slides, layouts, media, and metadata as a ZIP archive of XML files.
A .pptx file is a ZIP container holding XML parts that describe slides, master layouts, themes, embedded fonts, images, and speaker notes. Because PPTX is an open ISO standard (ISO/IEC 29500), it can be generated programmatically — which is what WebToSlides does when converting a webpage, HTML, or Markdown source into an editable presentation.
