What a .pptx file is

PPTX is the Office Open XML presentation format — a zip of XML with the media embedded, so a deck full of photos and video gets large quickly. PowerPoint, Google Slides, Keynote and LibreOffice Impress all open it; animations, transitions and custom fonts are the parts most likely to look wrong outside PowerPoint. Exporting to PDF is the reliable way to send a deck someone only needs to read.

Converting it

A .pptx file is commonly converted to .pdf, .ppt, .odp, .key or .mp4. It is a binary format, so a text editor will show unreadable characters rather than its contents.
