How to Download and Email Presentations in Google Slides
You can distribute your Google Slides files by either downloading a copy or sending them via email.
When you download a Google Slides file to your computer, it's available offline in a format you can edit in another program.
The presentation is converted and saved to your Downloads folder.
If instead you want to send a copy of the file directly to someone, you can email it.
The presentation is sent as an email attachment.
