Optimizer warning: error encountered while processing images

I'm having a problem optimizing a PDF in Acrobat (9.4.5). I first created a PDF from within PowerPoint (Office for Mac). When I optimize the PDF in Acrobat, I consistently receive a "conversion warning" message stating the an "error was encountered while processing images." I don't have a problem saving PDFs from programs such as InDesign or Illustrator. I tried converting the ppt to an earlier version but receive the same warning in Acrobat.

Any ideas how to fix this? I have a lot of .ppt files to convert into PDF. Thanks.

      I have a solution for this. You need to go into Advanced>Print Production>Flattener Preview and then apply the flattening first (you can compress the images right in there as well).

      Once you do that you can "Reduce File Size"... interesting that Adobe hasn't put that message into the error handling for this. ;-)

        I upgraded to Acrobat X two months ago. Since this time, I have optimized a large PDF (made from a PowerPoint file) once and it worked! I appreciate the advice and will keep it just in case.

        Thanks!

        I'm more inclined to think it's something in your Acrobat installation. Perhaps a corrupted preferences file. You could try uninstalling and installing Acrobat.

        What format are the images in Powerpoint? What method did you use for creating the PDF file?

        The PowerPoints consist of photos and text. I don't know the image formats because the ppts were put together by meeting attendees. I image most are jpg. I have about 10 ppt files to convert to PDF. I created the PDFs in PowerPoint: File>Save As PDF. I've tried a bunch of different things but I still receive the same error message.

        I just did a test with PowerPoint 2011 on the Mac. I placed several JPEG files into a set of slides. I created a PDF file the same way you did (File > Save As PDF).

        Then I used Optimizer in both Acrobat 9 and Acrobat X to reduce image resolution to 72 ppi. I encountered no errors in either version of the program.

        What version of PowerPoint are you using? Have you try re-saving the PPT files in Powerpoint (File > Save As) to rewrite the files?

        What settings did you use in the Optimizer?
