Are PowerPoint watermarks effective?

Watermarks are a good way to protect the presentation from being leaked online. But how effective are they really?

Watermarking your presentation with text or images in PowerPoint makes it simple to prevent anyone from trying to steal your work. After all, it's pretty clear that the content belongs to you. The downside is that the watermark can be easily removed by anyone who knows how to use Microsoft Office applications.

The best way to protect your work is to put a password and apply a watermark at once. In this case, only those with the correct password can access and modify the presentation. It also prevents people from just taking screenshots of the slides and sharing them online.
