It looks like the qpdf-converter source, along with everything else, is now on Github according to the Developer / Source Code links on the site.

https://github.com/QubesOS/qubes-app-linux-pdf-converter

Their source code seems to take the most obvious path... flatten it to an image printout then possibly do more? https://github.com/QubesOS/qubes-app-linux-pdf-converter/blo... https://github.com/QubesOS/qubes-app-linux-pdf-converter/blo...

Though at a quick skim I can't see any OCR steps.

I was wondering that myself, but one of the downsides mentioned is that you lose text search, which seems to suggest that OCR is not being used.
