Once done, click on the Close Master View button, which is available in the Slide Master tab.
Following that, go to the Home tab, click on New Slide, and choose the Title and Content option.

Slide Master vs. Themes
These are mainly two very useful methods to apply the same formatting to multiple slides at once. However, if you already have a presentation and you want to change the formatting, you can use the second option, i.e., Themes. Slide Master is handy only when you want to create a presentation from scratch. Although Slide Master changes the existing styling, Themes work better in that case.
How to apply the same formatting to all slides in PowerPoint using Format Painter
- Open a slide and select a text, object, shape, etc.
- Click on the Format Paint option.
- Go to another slide and select text/object/shape. And click on it.
Let’s take a deeper look at these steps.
To use the Format Painter, open a slide and select a text, object, or shape. It is the source object from where the Format Painter will copy the styling. After selection, make sure that you are in the Home tab. If so, you can find an option called Format Painter. Click on it.

Then, switch to another slide and click on the same type of content to apply the copied style. Having said that, you must choose text if your source has text formatting. Similarly, it is mandatory to click on a shape if you copied the formatting from the shape.
Note: The disadvantage of Format Painter is that it doesn’t store the formatting permanently. Having said that, once you use the formatting, it will be deselected. You will have to copy the source formatting again to apply it a second time on an object or any other content.
Pro tip: If you want to apply the same transition to all slides, select all the slides using Ctrl+A and apply a transition.
