Compressing a PowerPoint for use in Collaborate

1. Go to portal.office.com and select PowerPoint.

   Drag the large .ppt file onto the plus sign (“+”) to open it. 

3. ---

   Once PPT is open, go to “File”.

4. ---

   Select “Download As” and then “Download as PDF”.

   When your presentation is ready, click on “Download”.

The file will decrease as much as 90% in size and be a PDF, which is better for Collaborate and also for emailing or moving around.
