Extract background image from PowerPoint Presentation imported into Keynote

Welcome to the forums!

Keynote presentation documents are actually "packages" of files that the Finder presents as a single file. The slide backgrounds should be accessible in the presentation package. To show the contents of the package, in the Finder Control-click on the file, and choose "Show Package Contents". In the Finder window that opens you should see a variety of files, and some of those files should be the background images used in the presentation. I would suggest copying (not moving) those images to another location, make the necessary corrections, and the set them as the slide backgrounds from within the Keynote application. (The alternative is to make the changes directly to the images in the package, but that may risk corrupting the document.)

1. Yes, the image is removed and the package size will be smaller (at least that's what happens when I test it).

2. The default image seems to be the background image for the overall theme. (Perhaps if the document is imported and there is no specific theme attached, it defaults to the first image fill.)

3. I have no idea -- I believe that PowerPoint's format is a unified binary, so all of the resources used get stuffed into a single actual file. I may be wrong about this, however.

I still don't seem to be able to see the actual background images in the package. I can see all of the others images used in the presentation, but not the background image. I am really looking to extract the template backgrounds so I can use them in Pages & iWeb. Any ideas?

Welcome to the forums, JBL11!

For the background images that come with themes, you will need to extract them from the Keynote package. Go to the Keynote application, show its contents, go to Resources -> Themes, and you will likely find what you want in the Shared folder there.

Thanks for the help Tulse. I found em!
