I have a situation where we start with Keynote files, must convert them to Powerpoint and then back into Keynote before I can work with them.
The extra Powerpoint step is 100% necessary. The files need to be translated and the translation software doesn't accommodate Keynote.
The thing is when files are brought back into Keynote the resolution of the images are reduced. Is there any way to keep the quality of images intact while converting back and forth?
