PDF Pen has a script to reverse pages:

-- This script reverses the page order.

tell application "PDFpenPro 6"
if (count documents) > 0 then
tell document 1
set pageCount to count pages
if pageCount > 1 then
set halfCount to pageCount div 2
repeat with pageNumber from 1 to halfCount
move page pageNumber to after page (pageCount - pageNumber + 1)
move page (pageCount - pageNumber) to before page pageNumber
end repeat
end if
end tell
end if
end tell

Hello,

I have many pdf files for which I would like to change the pagination -- for example reverse it completely, from the last page up to the first page, or invert (put page 1 as page 2, and page 2 to as page 1; page 4 as page 3, and page 3 as page 4, and so on).

I would like to ask if there is any tool that can automate such tasks, and how it is possible.

Thank you very much in advance.

Best regard,
