I'm trying to merge and flatten layers, but there's not pdf optimizer, at least not under save as other. I have acrobat pro XI, version 11.0.14. Any clue how to add the optimizer? Is it an add-on?
To merge or flatten layers, select Layers under View menu > Show/Hide > Navigation .
Now click on layers icon on left navigation pane
Then select Merge layers or Flatten layers from option menu.
