Why does scaling during preflight not work on all documents?

[suemo22]

Hi,

I have an action wizard which scales pages for numerous pdf documents to a specified size (see action wizard below). It is able to scale most of the documents. However, for some documents, it doesn't scale them at all.  I accidentally figured out that the documents that do not scale conjure up the following error when I try to "Edit PDF" from the Tools menu, which leads me to believe the problematic documents have security. Is there a work around for this? Is there something that can be done to the documents ahead of time to prep them for scaling? I need to be able to scale pages for over 50 plus documents so I cannot save a copy of each one separately and then scale.

Here are the settings for the Preflight:

Thx.

Oh, I see, I had never thought to click the button on the right...I used to just go straight to the specified settings. TY very much!

You're welcome.  It's not very intuitive.
