To crop an image:
When you crop an image, a part of the picture is removed. Cropping may be helpful when a picture has a lot of content and you want to focus on only part of it.
Select the image you want to crop. The Format tab appears.
On the Format tab, click the Crop command.
Cropping handles will appear around the image. Click and drag one of the handles to crop the image.
Make sure the mouse is right over the black cropping handle so you don't accidentally select a resizing handle.
Click the Crop command again. The image will be cropped.
To crop an image to a shape:
Select the image you want to crop, then click the Format tab.
Click the Crop drop-down arrow. Hover the mouse over Crop to Shape, then select the desired shape from the drop-down menu that appears.
The image will appear formatted as the shape.
You may want to crop the image to the desired size before cropping it to a shape.
To add a border to an image:
Select the image you want to add a border to, then click the Format tab.
Click the Picture Border command. A drop-down menu will appear.
From here, you can select a color, weight (thickness), and whether the line is dashed.
The border will appear around the image.
Image adjustments
PowerPoint offers several options for changing the way images appear in your slide show. For example, you can add a frame, make image corrections, change the image's color or brightness, and even add some stylish artistic effects. These options are located in the Adjust and Picture Styles groups on the Format tab.
When you're ready to make adjustments or experiment with the look of an image, select the picture and choose one of these options from the Format tab.
Corrections: This command is located in the Adjust group. From here, you can sharpen or soften the image to adjust how blurry or clear it appears. You can also adjust the brightness and contrast, which controls how light or dark the picture appears.
Color: This command is located in the Adjust group. From here, you can adjust the image's saturation (how vivid the colors are), tone (the temperature of the image, from cool to warm), and coloring (changing the overall color of the image).
Artistic Effects: This command is located in the Adjust group. From here, you can add artistic effects such as pastels, watercolors, and glowing edges.
Picture Styles Group: This group contains a variety of styles you can apply to your picture, such as frames, borders, and soft edges.
