Google Slides: Share a presentation

Share a presentation with specific people, Share a link to a presentation

Note: Sharing options vary by group size:

• Up to 100: You can let up to 100 people with view, edit, or comment permissions work on a Google Docs, Sheets, or Slides file at the same time.
• 100 or more: When 100 people or more are accessing a file, only the owner and some users with editing permissions can edit the file. To let more than 100 people view your file at the same time, publish it as a web page instead.

You can choose if your file should be available to anyone or restricted to only the people with access. If you allow access to anyone with the link, your folder won't restrict who can access it.
