Sharing a finished presentation with people who may not have PowerPoint installed is the last step.
| Format | Use it for |
|---|---|
| .pptx | PowerPoint's own format — fully editable |
| A fixed copy, one page per slide, always opens even without PowerPoint | |
| Video | File → Export → Create a Video — turns the whole presentation, including any timed animations, into an .mp4 for when nobody needs to interact with it live |
A presentation with several full-resolution photos can grow to tens of MB, slow to email or upload. File → Info → Compress Pictures reduces every embedded image to screen resolution in one step, usually shrinking the file dramatically with no visible quality loss on a projector or screen.
