Does Microsoft PowerPoint run on Linux?
Verdict: Partly
Partly. PowerPoint has no Linux version, but PowerPoint for the web runs in a browser on Linux and free suites open and present .pptx files offline.
There is no PowerPoint for Linux and there never has been. Microsoft's system requirements for Microsoft 365 at home list Windows and recent macOS versions only.
PowerPoint for the web is the closest thing to keeping what you had. It opens your existing decks from OneDrive, lets you edit them and runs the slideshow full screen. Presenter view and some animations and transitions are limited compared with the installed app, and you need a connection, which is a real risk if you are presenting in a hall with poor wifi.
Offline, LibreOffice Impress and ONLYOFFICE both open .pptx. Text, images and simple builds come through. Fancy transitions, embedded video and unusual fonts are the parts that break, and a deck that looks right on your screen can reflow on someone else's.
The safe habit for anything that matters is to export the finished deck to PDF and carry that as a backup. A PDF opens anywhere and looks the same on every machine in the room.
