# kj-slidepacker

> to be used with exports from [sent-web](https://sent-web.site), LaTeX Beamer, or any other source of PDF presentations.

converts a `.pdf` presentation into a "fake" `.pptx` by rendering each page as an image and pasting it onto a blank slide.

output slides are **not editable**, this is intentional. 

the goal is just to get a pdf into pptx format for corporate compliance purposes (e.g., when someone absolutely **NEEDS** a `.pptx` and would go crazy if the file is not sent with an extension that says **• P P T X**).
