PowerPoint to pdf -- loss of image quality (samples provided)

[Guest]

Hi there. We hope we can get some competent help. We tried to solve this for the past couple of hours, but no luck.

We have a PPT PowerPoint file (MS Office 2007) which includes a couple of screenshots and other images, all in excellent/sufficient quality, but once we try to save the file as a PDF, the image quality decreases dramatically.

Please note, we tried both the PowerPoint 'print as pdf' function, as well as converting the PPT directly in/through Adobe Acrobat. Same result. We played with the compression options, trying to minimize or even entirely switch off compression, no luck. We did some (safe) registry changes for PowerPoint, as suggested in other boards, also no luck. We tried many different pdf converters (not only Acrobat), nothing.

Here's the picture quality in PowerPoint: http://ibin.co/2JfaGNGXCiXd

Picture quality in the generated pdf: http://ibin.co/2JfaNF8Br5OQ

PDF picture issue close-up (at 100% zoom level): http://ibin.co/2JfaRImLmXaw

What are we doing wrong?

Thank you for your help!!

Hi ste14978294,

Please let me know the exact dot version of Acrobat installed on your computer?

Try the below settings : -

Open Acrobat, navigate to Edit menu -> Preferences -> Convert to PDF categories -> Microsoft Power Point -> Edit Settings -> Adobe PDF Settings : High Quality Print.

Click Ok to confirm the changes.

Regards,

Aadesh

Aadesh, Acrobat is Version 2015.009.20071

Will try your suggestion now and report on the result here.

Aadesh, I just tried (and rest assured it was done precisely as you suggested) and I am still getting the same bad image results. No improvement whatsoever: http://ibin.co/2JfaRImLmXaw

The Image Link above shows how the images appear in the pdf at 100% zoom level. Plus:

1) no improvement when changing the zoom level or screen resolution

2) the image has never been resized

3) all images in the PowerPoint file are equally affected

4) in PowerPoint, these same images look very good

Hi ste14978294,

Have you tested this issue with other PowerPoint files?

Also let me know the steps followed to convert the file?

In the mean time open Acrobat, navigate to Help menu -> Repair the Installation.  Also, check for the updates under the help menu.

Regards,
Aadesh

Same problem for me. Followed your instructions exactly. Photos HD in PPT are now low quality in PDF

same issue, tried the fix with no luck. Have been re-screen shot-ing the needed images again that I used in the PPT and am pasting them into the PDF version... not fun

What is the ppi (pixels per inch) of your images? Were they resized after putting them into PowerPoint? Bigger or smaller? What software did you use to take the screenshots? Where did the other images come from? Did you copy them in or insert them?

When you make the PDF, do you use the Acrobat tab in PowerPoint?

Hello. The latest update to the MS Office site fixed this absurd bug. I was experiencing the same problem described above before the fix but after the latest updates, PDFs are again looking as they should (when quality is set to "High" in PPT). For details on the latest PPT update –16.15 (Build 180612)– please  see here:
