I have a number of pdf documents with more than 1,500 pages. The left pages are rotated 90 degrees left and the right pages are rotated 90 degrees right. Using the Acrobat view and rotate feature, all pages within the document rotate. This makes 'the odd pages 'upright' but the even pages are then 'upside down'.
What is an efficient method to rotate all these pages to an "upright" position that reads 'normally'?
My goal is to covert these into searchable pdf documents using Acrobat Pro XI.
