How can you add a watermark to your slides?

Adding a watermark to your slides is effectively accomplished by using the Slide Master view. This method allows you to insert either a text box or an image that acts as a watermark on all slides within a presentation. The Slide Master serves as a template for your entire presentation; by adding a watermark here, it automatically appears on every slide that uses that particular layout, ensuring a consistent and professional look throughout your presentation.

This technique is particularly useful for branding purposes, such as displaying a logo or a "Draft" label, which you may want to be visible on every slide without having to add it individually to each one. It streamlines the design process and maintains a cohesive appearance.

In contrast, inserting a watermark during Slide Show mode is not feasible, as that mode is primarily intended for presenting rather than editing. Using the Format tab is more focused on adjusting elements that are already part of your slide design rather than creating new background elements. Lastly, adding a footer in the Notes section is specific to presenter notes and won’t show on the actual slides during a presentation, rendering it ineffective for displaying a watermark to your audience.
