How to use Slide Master to unify the background of slides

1. Use WPS Office to open the presentation file and click the View tab → and then click the Slide Master button.

2. After we jump to the Slide Master interface, click the Object Formatting button on the right side. We set the background in the right column as needed, and click Apply to All.

3. Now click the close button to exit the editing process. 

Note: (a) Now all new slides will use this unified background. (b) If we use this feature only on a single slide that does not belong to any slide master, only the background of this slide will be changed.

You will be the amazing reporter with WPS Presentation, which could alternative to Microsoft powerpoint.
