Before sharing a presentation, you'll definitely want to make sure it doesn't include any private information. You probably don't want others to edit it either. Fortunately, PowerPoint provides a number of tools to help users check and protect presentation files.
Whenever you create or edit a presentation, personal information such as the document author may automatically be added to that file. You can use the Document Inspector to remove this type of information before sharing the PowerPoint file with others.
Since some changes are permanent, we recommend using Save As to create a backup copy of your presentation before using the Document Inspector .
How to use the Document Inspector in PowerPoint
1. Click File > Backstage view .
2. From the Info panel , click Check for Issues > select Inspect Document from the drop-down menu.
3. The Document Inspector will appear. Check or uncheck the boxes of the content cells you want to evaluate, then click Inspect . This example uses the default options.
4. The test results will show an exclamation point for any category it detects sensitive data. And it also has a Remove All button for each of those categories. Click Remove All to remove the desired data.
5. Once done, click Close .
By default, anyone with access to your presentation can open, copy, and edit the content inside unless you set protection for it. There are several ways to protect a presentation depending on your needs.
How to protect documents in PowerPoint
1. Click the File tab to go to the Backstage viewer .
2. From the Info panel , click Protect Presentation .
3. In the drop-down menu, click the option that best suits your needs. Here, select Mark as Final . Marking a presentation as final is a great way to let others know not to edit the file. In addition, PowerPoint still has some options that give you more control if needed.
4. A dialog box will appear, prompting you to save the file. Click OK .
5. Another dialog box will appear. Click OK .
6. The presentation will be marked as final. Whenever someone else opens this file, a Marked as Final bar will appear at the top to let others know not to edit this document.
Note, marking the presentation as final does not prevent others from editing it because they can choose Edit Anyway . If you don't want someone to edit your PowerPoint document file, use Restrict Access instead .
