Removing Objects & Images from 600 page Adobe Acrobat X file - How?

Solution 1:

It was much easier in an earlier version of Acrobat Pro (using the Preflight tool). Here's how I managed to remove all images using the preflight tool of Acrobat XI:

1. Use Preflight tool to move images to separate layers
2. Set image layers to invisible (and disallow export, though I'm not sure if that had any influence)
3. Go to Tools, to the security menu on the right and use the option to remove all hidden elements
4. Save PDF

Solution 2:

I did this with Acrobat XI pro and Foxit phantom: 1.open file in acrobat XI, open Preflight with Ctrl+Shift+X 2.go to create PDF layers>create separate layers for... 3.after layers' been made, save the file 4.open the file in foxit phantom 5.notice which layer has those objects you want to remove, delete that layer.

also you can make layers invisible in Acrobat, but with Foxit you can delete a layer permanently!
