Import PPT/PDF to impress.js

Feature Request/Idea : A way to **import a pdf or ppt** presentation to an impress.js presentation.

I could not find anything related to this apart from this "[PPT-Extract-Impress](https://github.com/arthurzaczek/PPT-Extract-Impress)" .

The basic idea is : I want to work with impress.js presentations only , but to do so, all my existing presentations (either in ppt or pdf or both) needs to be converted into impress.js presentations. Most of the existing solutions including above solution, work the following way : Convert all slides to images and add them to current presentation. This solution is not the best as it takes away the possibility (and very many others) of formatting, copying or even searching text in the pdf/ppt which we had.

Any ideas how to go about achieving this. (maybe use some other tools to support etc)

Start by reviewing impress.js and the linked PPT-Extract-Impress project to understand the existing presentation structure and conversion approach. Define what PDF and PPT import must preserve, including editable formatting, copyable text, and searchability, then use those criteria to evaluate whether the proposed feature is complete.
