Step-by-Step Instructions for Adding a Watermark
To insert a confidential watermark in PowerPoint, open your presentation and go to the 'Design' tab. Click on 'Slide Master' and select the slide layout where you want to add the watermark. Go to the 'Insert' tab, click on 'Text Box,' and type your confidential message. Format the text as needed, then right-click on the text box and choose 'Format Shape.' Under 'Fill,' select 'Picture or texture fill' and choose an image to use as the watermark. Adjust the transparency to make the watermark less noticeable. Save your changes and you're done!
