Formatting pictures in PowerPoint can make it easier to personalize your presentation.
Have you inserted a picture onto a slide that you want to trim or make appear smaller on the slide? Perhaps you'd like to add an artistic effect or border to the image to make it stand out from the slide's background. You can use PowerPoint's picture tools to help you modify the picture style and shape, add a border, crop, add artistic effects, and even compress pictures.
Optional: You can download this example for extra practice.
Corner handles will allow you to simultaneously crop the image horizontally and vertically.
You may want to crop the image to the desired size before cropping it to a shape.
