We’ve all probably run into this at one point or other: you’ve created a visually stunning Powerpoint deck, but the file is absolutely huge! You can’t email it, or it just takes forever to open or save it… well there is a solution:
In PPT for Windows, file > save as — tools, look for “Reduce file size“
In PPT for Mac, file > reduce file size
This will shrink the total size of your Powerpoint file by optimizing the images you’ve used.
