I have a PDF file containing slides, but the document has been created with two horizontal slides per (portrait) page (yes, a "handouts format")
I want to be able to scroll pages using page Up/page Down, but unfortunately the "fit size" option in pdf viewers will fit the whole page with the two slides. It's written too small and it's uncomfortable to read.
Is there a way to resplit the pdf with one slide per page, or to find a very convenient way to scroll half a page at a time with page Up/Down (and it scrolls EXACTLY half a page, otherwise it's super annoying)
EDIT I don't own the source file unfortunately, and I'm running most on the time on Windows using Foxit Reader or Lumin PDF for the Drive
