How to Make a Microsoft PowerPoint Presentation Read-only

Sharing a PowerPoint presentation with others is common practice in business settings. However, you may not want recipients to edit or change your carefully crafted presentation. Making a PowerPoint presentation read-only prevents unauthorized changes while still allowing viewers to see the content.

There are a few simple ways to make a PowerPoint presentation read-only, both built into PowerPoint itself and using other Microsoft services. Read on to learn how to lock down your presentation and protect it from unwanted alterations.

Mark the Presentation as Final in PowerPoint

The easiest way to make a PowerPoint presentation read-only is to mark it as final right within PowerPoint. Here are the steps:

1. Open the PowerPoint presentation you want to make read-only.
2. Click on the “File” tab.
3. Select “Info” on the left side of the menu.
4. Click on “Protect Presentation” and choose “Mark as Final” from the drop-down menu.

Marking a presentation as final sets it to read-only mode within PowerPoint. Other users will be able to view the presentation but will be prevented from making changes.

There is also an option to select “Always Open Read-Only” which prompts users to actively choose to edit the presentation rather than opening it in editing mode by default.

The main downside of this method is users can still override the read-only status by clicking “Edit Anyway.” So it discourages edits but does not completely prevent them.

Set File Permissions in SharePoint or OneDrive

If you store your PowerPoint presentation in SharePoint or OneDrive, you can restrict editing permissions through those platforms. Here’s how:

1. Upload or save your PowerPoint file to OneDrive or a SharePoint document library.
2. Right click on the file and select “Manage Access.”
3. For each person you share with, change their access from “Can Edit” to “Can View.”

With editing rights revoked at the platform level, users will only be able to view or download the presentation in SharePoint or OneDrive. To enable co-authoring abilities again, you can restore edit access.

Save as PDF

Another way to effectively make a PowerPoint presentation read-only is to export or save it as a PDF. PDF files are inherently non-editable documents.

Simply open your presentation in PowerPoint and select “File > Export > Create PDF/XPS.” The presentation will save as a PDF, after which you can share or distribute the new non-editable version.

If you want recipients to still be able to view the PowerPoint and its animations/transitions, you can also save it as a PowerPoint Show (.ppsx) from the “Save As” menu. This format runs the slideshow without the editing interface.

Set a Read-Only File Attribute

For Windows users, you can make a PowerPoint presentation read-only by adjusting file attributes rather than relying on PowerPoint settings.

1. Locate your PowerPoint file in File Explorer.
2. Right click, select “Properties”, and click the Attributes tab.
3. Check the box next to “Read-only.”
4. Click “OK” to save the changes.

Now Windows will treat the file as read-only system-wide, blocking any program from opening it in an editable mode. You can repeat these steps to remove the read-only status later on.

Use DRM Software

If you need to share presentations with highly sensitive information, consider using digital rights management (DRM) software. DRM tools like Microsoft Azure Rights Management let you encrypt files, set detailed usage permissions, and revoke access remotely.

While the methods above discourage or hinder editing, DRM solutions like Microsoft’s provide complete protection of intellectual property. Explore enterprise-grade DRM tools if unauthorized changes to a shared presentation could cause harm.

Conclusion

Preventing unintended modifications to a PowerPoint presentation ensures your original version remains intact. The techniques covered in this article, from marking as final to adjusting file attributes, make it simple to keep your presentation read-only and guarded from unwanted changes.

Choose the read-only method that aligns with your use case, whether it’s quick sharing inside your organization or distributing sensitive materials with partners. Just remember edits can still happen if recipients override some read-only settings within PowerPoint itself. For true restrictions, rely on platform permissions, file formats like PDF, or robust DRM systems.
