When to use Compress PowerPoint
Decks are the worst offenders for file size because every slide tends to carry a full-resolution image. Recompressing those usually cuts the file dramatically while text, layout and slide structure stay exactly as they were. Worth doing before emailing a deck or uploading it to a portal with a size cap.

Troubleshooting
Photos on slides look soft when projected
Projection magnifies compression artefacts. Use Basic for anything shown on a big screen.
Embedded video did not shrink
Only images are recompressed. Video inside a deck is untouched and stays the same size.
The upload is rejected before anything happens
The file is over the 20 MB cap. Compress it first, or split a long PDF into smaller files and process them separately.
