How can I make a Keynote file non-editable? I have a PowerPoint presentation that I am converting to Keynote to distribute to students; however, I do not want other users to be able to edit the presentation.

Is there a way to make a Keynote file read-only, non-editable?

I don’t want to convert it to PDF files as I will lose the animations, or to convert it to a video file as the students would lose the ability to read the presentation at their own pace.
To make a Keynote presentation non-editable, you can export the slides as images and replace all the original slides with the images.
