PPTX
Office Open XML Presentation
PPTX is a ZIP of XML with one part per slide, plus the themes, layouts and masters that decide how each slide is drawn. The content is easy to read out; the design is a rendering problem, which is why converting a deck faithfully needs PowerPoint itself.

Opening a .pptx file
If you landed here because something handed you a .pptx file and
nothing on your machine will open it, converting it to a format you already have a
reader for is usually faster than installing new software. Every conversion above runs
in this browser — the file is not uploaded, so it works on a locked-down work machine
and on a file you are not allowed to send anywhere.
