Please add the possibility of exporting vector based images as they do not lose any image quality. With PNGs, you lose image quality every time you save it in a PowerPoint file. Although the workaround is to turn off compression, it increases the file size.
Thanks for the idea!
As a workaround, you can use the current Export to PDF option for a vector based format.
We will continue to monitor this idea for overall community feedback.
