What is the optimal/maximum file size for a Powerpoint that a large team is collaborating on, stored in Sharepoint?

Gee, Stacey 21

We have a large team of 30-40 people that will be editing a shared Powerpoint presentation using a Sharepoint/Microsoft 365 - the file size is edging to 1GB. It is incredibly laggy for some - and some say they have issues editing within the Powerpoint/Sharepoint web client, and it takes too long to load via their desktop app.
Is there an official limit or optimal file size guidance for collaboration this way?

SharePoint uses PowerPoint for the Web, which has severe file size limitations, given that 1Gb is next to nothing in a presentation. Here is the Microsoft page on this subject:

Thanks very much for your link/response!

PowerPoint for the web can open files up to 2 gigabytes (GB) in size.

Interesting that PPWeb can technically open up a 2GB file, but we are experiencing slow load times at a 1GB file. I wasn't sure based on reading the article - but if folks try to edit the file via Desktop App; in addition to having better editing ability, would it potentially run faster?

That depends on what part of the workflow is causing the slowdown, so it's easier to just try editing in the desktop version and see if that brings an improvement.
