How to swab , tow column pages for Arabic

Hello 
 
I want to translate an English  PDF file into Arabic
 
the page is formatted in tow columns
as you know that Arabic is RTL Right to Left reading order
and right Aligned
 
how to deal with this type of format to be suitable for Arabic when saving target as?
 
a right column must be on the left and verse versa after exporting (save target as) 
 
Best regards
