About PPTX

PowerPoint OOXML presentation.

PPTX is PowerPoint's open XML container. Slides, layouts, and notes are stored as a ZIP of XML and media. This viewer unpacks the archive locally with JSZip, walks the slide XML for text runs, resolves image relationships, and pulls speaker notes from the notes part. Animations, transitions, and exotic embeds are stripped — what you get is a clean, readable outline of every slide with its imagery and notes.
