Can I prevent people from editing my PowerPoint presentation?

To preserve the integrity of your PowerPoint presentation, you can try to prevent others from editing it. Depending on the version of Office you have, there are a few things you can do to block editing, or at least make it more difficult.

Use the access restriction function (for companies and enterprises only)

You can use the Restrict Access feature to protect your PPTX file from edits, but this feature is only available to Microsoft 365 for Business or Enterprise , and your organization administrator must enable it in the Microsoft 365 admin panel . That means if you are using any version below Microsoft 365 for Business, such as Home or Family, then you will not have this feature.

Yes is subscribed to a version that supports this feature and if your organization administrator has enabled it, you can locate “Restrict access” under File> Information> Protect Presentation.

Click Restrict access.

You can then set restriction types and file access expiration dates.

Visit the official Microsoft documents site for more information on Information Rights Management and how to use this feature.

Make your presentation read-only or mark it as final

Make your presentation read-only or marking it as final doesn’t actually make your presentation uneditable. What this does is discourage others from making edits. It’s also good for avoiding accidental edits, as it allows you to opt-in before you can make changes to the content.

To make your presentation read-only or to mark it as final, open your PPTX file and click on the “File” tab.

Click File.

Then click on “Information” in the left panel.

Click Info.

Now, in the Protect Presentation group, click on “Protect Presentation”.

Click the Protect Presentation option.

Once selected, a drop-down menu will appear. You can choose between these two options to make your presentation read-only:

  • Always open read-only: This prompts the reader to choose to edit the presentation, preventing accidental edits.
  • Mark as final: this lets the reader know that this is the final version of the presentation.

Selecting any of the options will prevent the reader from editing the presentation, unless they choose to do so by clicking the “Edit Anyway” button on the banner.

The read-only note.

While making your presentation read-only serves a purpose, it is a weak form of protection if you really want to prevent others from editing your content.

Password protect your presentation

PowerPoint has an option that allows you to encrypt your presentation and only those with the password can access it. Again, this does not fully protect the content within the presentation, but if only those with the password have access, the chances of the presentation being edited are certainly less.

Warning: this password is not stored anywhere on your local machine. be sure that save password in a safe place. If you forget or lose your password, you will not be able to access the presentation again.

To password protect your presentation, open PowerPoint, click the “File” tab, click “Information” in the left panel, and then click the “Protect Presentation” option.

Click the Protect Presentation option.

Then click “Encrypt with password” in the menu that appears.

Click Encrypt with password.

The Encrypt Document window appears. Enter your password in the Password text box and then click “OK”.

Please enter a password.

Re-enter the password and then click “OK” again.

Reenter password.

Now anyone trying to open the presentation will need the password to access it.

Enter the password to open the presentation.

This method is more secure than simply making your presentation read-only. However, you are simply preventing people from opening the PPTX file. If they have the password, they can also edit the content of the presentation. Be careful who you share the password with. If you are concerned that password has been exposed , change it immediately.

Save your presentation as an image

If you want to hand over your PPTX file to someone, but don’t want them to be able to copy or edit the content (at least easily), you can convert PowerPoint presentation to image file and send it that way.

Open the PowerPoint presentation, click “File” and then click “Save As” in the left panel.

Click Save As.

Browse to the location where you would like to save the file and then, in the “Save As” box, choose the type of image file where you would like to save your presentation. You can choose between:

  • Animated GIF format (* .gif)
  • JPEG file interchange format (* .jpg)
  • Portable network graphics format PNG (* .png)
  • TIFF tag image file format (* .tif)
  • Scalable vector graphics format (* .svg)

Choose an image file type.

Once you save your presentation as an image, you can send it to the desired recipients.

At the end of the day, there is no solid way to 100% protect your presentation. You can kindly ask recipients not to edit the content, to password protect your submission so that only those you want access to can access it, or to convert your presentation to an image or Pdf , but even with these measures, if someone so wishes. edit something, they can always find a way.
