How to compress PowerPoint presentations and reduce picture file size
FEBRUARY 26, 2019
Did you know PowerPoint has a built-in picture and video compression tool? Images: Select a picture on any slide and go to the Picture Tools Format tab on the ribbon. Choose Compress Pictures in the top left corner: the pop-up box shows you the resolution options you have for the image. Go into the ppt folder and there are even more unfriendly folders. When you open it up in PowerPoint your picture will have been replaced by a white box with a red cross in it.
