How do I extract pages using Adobe Acrobat 6.0.x and save them as PDF 1.4 (not 1.5)?
Thanks to Marc Pawliger, I finally have the answer! “It’s not that easily found, but pick Advanced> PDF Optimizer and choose Compatible with: Acrobat 5.0 and Later in the popup menu at the top of the page. The file will save as PDF 1.4. I didn’t check whether links are preserved, but I would expect them to be.
