Splitting a single pdf page into two

[Dave5F97]

I'm trying to turn a series of A4 pages with 2 A5 pages on them into a series of two separate A5 pages to create pfs of each A5 page to give to a printer to turn into a booklet. I can get individual A4 pages with difficulty from the 8 A4 pdf file but then when I try and split the single a4 pdf into 2 the programme says there are already 1 or less pages, it won't let me put in 0.5 pages. It doesn't seem to want to allow me to crop the page down to A5 size and save it. Does anyone know how to do this? The search comes up with pretty much everything but the solution to my particular problem!

You can use the crop tool at Tools > Edit PDF

Thanks
It seemed obvious to me that that would be the way to do it but it wouldn’t work until I reinstalled Acrobat – it took me 5 attempts and a technician 2 hours working my machine online before I got it properly installed – no idea what was the problem but it seems to be working now.

Actually I've just realised that this just gives you an A5 block in an A4 page. Not only that if you have a pdf with more than one page, crop just crops the one page and if you then save it it saves all the subsequesnt and previous pages. Also my printer says he just wants single A4 pages and I can't turn an A5 into an A4. The help is really useless, you would have thought this was a simple thing to do, that maybe other people would want to do and there would be a process for it. I can take each A5 page and save it as a jpg file but this loses the quality of the image, so i'm still stuck.

With the preflight tool of Adobe Acrobat DC Pro you can scale A5 to A4.

You can do it easily using this (paid-for) tool I've created exactly for this task: http://try67.blogspot.com/2013/12/acrobat-split-and-sort-scanned-booklet.html

You'll find a free page resizing tool here:

It doesn't split the pages, just crops or expands them to the specified size.
