Microsoft PowerPoint provides a suite of basic image-editing tools, including the ability to change the opacity of an object or photo. If you want, you can even change the transparency of only a certain section of an image. Let’s take a look!

Changing the Opacity of an Image or Object

If you want to make an entire object or image more transparent, open PowerPoint and insert an image by clicking Insert > Pictures. When the photo is on a slide, select it and a border will appear around it.

Next, right-click the image, and then select “Format Picture.”

The “Format Picture” pane will appear on the right; click the Image icon.

Here, you’ll see a few options. Click the arrow next to “Picture Transparency” to open its drop-down menu. Click and drag the “Transparency” slider to adjust the opacity of the image.

The scale is:

  • 0 percent: Fully opaque
  • 100 percent: Fully transparent

We’ve set ours to 50 percent.

You can see below what our selected object looks like now.

When you’re happy with the level of transparency you’ve set, close the “Format Picture” pane.

Changing the Opacity of Part of an Image or Object

Before we jump into changing the opacity of part of an image, it’s important to note this feature only works on objects that are inserted as a picture. So, if you insert an image inside a shape, this option won’t be available.

With that in mind, click “Insert,” and then select “Pictures” from the “Images” group. In the drop-down menu, select whether you want to insert an image from an online source or your machine.

Navigate to the image you want to use, select it, and then click “Insert.”

After the image is inserted, make sure it’s selected, and then click “Picture Format.”

In the “Adjust” group, click “Color.”

Select “Set Transparent Color” near the bottom of the menu.

Your cursor change, as shown below. Use it to click the color in the image you want to make transparent.

After you select a color, every instance of it in the image will become fully transparent and take on the color of the background of the slide.

Unfortunately, this is an all-or-nothing tool. The part of the image you select will either become completely transparent or remain completely opaque.

Note also that if you print your presentation, the transparent areas of the images will be white on the hard copy.
