Why is there no save button for Google applications?

You may notice that there is no Save button for your files. This is because Google Drive uses autosave, which automatically and immediately saves your files as you edit them.

How to Save an image from Google Doc?

Right-click on the Google Docs image that you want to download. Click on View more actions > Save to Keep.

Does Docs AutoSave?

AutoSave is a new feature available in Excel, Word, and PowerPoint for Microsoft 365 subscribers that saves your file automatically, every few seconds, as you work. AutoSave is enabled by default in Microsoft 365 when a file is stored on OneDrive, OneDrive for Business, or SharePoint Online.
