You have a PowerPoint presentation you need to share with others, such as an explanation of unique training materials. But how can you protect it from being copied or modified? Protecting the intellectual property in your PowerPoint slides is actually not that hard. Watch this video tutorial or skip to the article to learn how this can be done.

How to protect PowerPoint slides

Method #1: Upload Your Slides to a Secure Cloud and Share via Link

You can use iSpring Cloud to distribute the presentation to your audience on the web without giving them the source file. This service will convert your presentations to HTML5 format and securely store them in the cloud. You can share the link to your slides online so your learners or colleagues can view them on any desktop or mobile, but can’t copy, edit, or download them. 

  1. To share your slides, register an account with iSpring Cloud and log in.

  1. Upload your file to the cloud and then select Share so you can access the protection settings.

  1. In the Content Protection settings, enable the options you need. iSpring Cloud allows you to:
  • Set a password for your file.
  • Restrict sharing (users can view the presentation but can’t share it with someone else).
  • Restrict downloading (users can view your presentation but can’t save it on their computer).

  1. When you are all set with the protection settings, share the presentation with your audience. There are two ways to do this:
  • Use a short link to share your file on social media.
  • Send a link to your viewers via email.

Method #2. Protect Your Presentation with a Watermark or a Password

If you need to safeguard your PPT presentation and distribute it using a physical device or place it on the web providing a possibility for users to download it, a good way to prevent your project from being stolen is to protect it using iSpring Suite. It’s an eLearning authoring toolkit for PowerPoint that offers a bunch of presentation protection settings. 

Download iSpring Suite for free and install it on your computer. Open the presentation you want to keep safe, switch to the iSpring Suite 9 tab, and click Publish

In the opened window, you can configure the security settings you need. 

1. Copyright your PowerPoint slides by adding a watermark

With iSpring Suite, you can watermark your presentation with, for example, your corporate logo or copyright notice like © 2020 John Smith. It’s possible to set the watermark’s transparency and position on the slides. You can also specify a webpage that will open when your viewers click on the watermark. It could be anything from terms of use to your profile page on a social network site.

2. Set a password

This option is pretty straightforward. You create a password and no one can view your presentation without entering it first.

3.  Restrict time

You can set a special time period when your audience will be able to view your presentation. For example, you can set up a 2-week interval when your slides will be available.

When you’re finished with the settings, save any changes and publish the slides. By default, the output presentation is saved on your PC. You can then transfer it to a pen drive or CD and distribute it to your learners or colleagues.

Method #3. Make Your Presentation Read-Only

This method won’t prevent your copyrighted PPT slides from being copied and shared, but it will protect them from being modified. The upside is that to lock a presentation from editing you don’t need any third-party services – you can do this right in PowerPoint by using the Mark as Final option. When a presentation is marked as final, other users can read and view it, but can’t make any alterations. 

To lock the slides, click the File tab in PowerPoint and choose the Protect Presentation command in the Info pane. In the drop-down menu, select Mark as Final. That will set your presentation in read-only mode.
