title: How to vertically split a PDF e-book with collation (2-page per sheet to 1 sheet per page)
body: <p>I have a scanned e-book with 2 pages per sheet. I was able to crop the e-book for the white borders on four sides. Since the two book sheets are on one single page, I am getting bad view on e-reader like kindle. I am trying to split the e-book to 1 page per sheet. Is there  a way to to do this in acrobat professional?</p>
  
  <p>I thought of cropping the pdf as two batches (left and right) and merging them together but the page collation will go off completely. the pages won't come adjacent to each other. I will get 1,3,5,7 upto 101 as one pdf and 2,4,6....100 as another PDF</p>
