Among PowerPoint 2010's newest and most magical abilities is the Remove Background option that lets you remove the background from an inserted picture. This can be a great feature if you want
to remove a sky, a wall, any backdrop, or something else in a photograph so that the slide background shows through within the removed parts of the
Follow these steps to learn how the Remove Background option works:
- Before you start, we assume you already have a picture on your slide. It helps if the parts of the picture you want to remove are fairly
different in color than the rest of the picture, although as you get more proficient with PowerPoint's Remove Background option, you will be able
to work with more complicated compositions. Look at our sample picture, as shown in Figure 1 -- you will notice that the color of
the sky is distinctly different than the rest of the picture.
Figure 1: Picture with a fairly distinct background and foreground areas
- Select the picture to display the Picture Tools Format tab (highlighted in red in Figure 2) of the
Ribbon. Activate this tab by clicking on it -- locate the
Adjust group which includes different options to remove the background from a selected picture. Now click the
Remove Background button (highlighted in blue in Figure 2).

The Picture Tools Format
tab is a contextual
tab. Contextual tabs are special tabs in the
that are not visible all the time -- they only make an appearance
when you are working with a particular slide object which can be edited using special options.
Once you click the Remove Background button, PowerPoint makes a guess and shows the areas that it ascertains you want to
remove (see Figure 3). In addition, note these behaviors:
- You will see a selection box, indicated by the eight handles shown in Figure 3. Four of the eight handles in the selection box
are corner handles. The other four are side handles. You use these handles to resize the selection box.
- You have the new Background Removal tab on the Ribbon, highlighted in green in Figure 3 -- we will explain
the options in this tab later within this tutorial.
- The active slide within the Slides Pane will show a preview of
the picture with the background areas removed, as shown highlighted in blue in Figure 3. Don't worry -- nothing is removed as yet
-- this is just a preview.

Figure 4 shows a zoomed in part of the picture -- you can see that a major portion of the picture has been covered with a magenta
overlay. This magenta overlay indicates the background areas to be removed. Only those areas that still show the original colors of the picture
will be retained. Unfortunately, in this example you see that the man loses his head and both his palms as a part of the background removal.
Figure 4: Magenta overlaid areas indicate the background selected for removal
At this stage, you have two options. The simpler option is to drag the handles of the selection box to help PowerPoint decide the areas of the
picture you want to remove or retain:
- You remove more areas by resizing the selection box smaller. Click on any of the handles and drag inside the picture area -- wait for a while
for PowerPoint to add more magenta areas to your picture.
- You retain areas by making the selection box larger. Click and drag any of the handles outwards – you can press the Ctrl key
and drag any one of the four corner handles outwards to select all areas of the picture as shown in Figure 5, below. Notice
that the selection indicated by the non-magenta areas is abysmal at this point of time, and that’s OK since we will modify this further.
Figure 5: Modified selection for the background removal
For simple pictures, this is all you need to do – and everything will be automatically selected. If you are happy with the results, go ahead and click the Keep Changes button
within the Background Removal tab of the Ribbon. Alternatively, you can click anywhere on the slide outside the
picture area to remove all magenta overlaid background areas of the selected picture. In our case, this approach does not work – and we explain how to fine-tune your selection next.
- The second, and more involved option is to manually fine-tune the selection using the options within the Refine group of the
Background Removal tab that you can see in Figure 6.
Figure 6: Refine options within the Background Removal tab
These options are explained below:
Mark Areas to Keep: Click this button and draw lines by dragging within the areas that you want retained in the picture. For some reason, diagonal, longer lines work better than horizontal or vertical lines.
you draw will be indicated with a plus label (see Figure 7). You can always undo your last few markings by pressing the Ctrl+Z keyboard shortcut.
- Mark Areas to Remove: Click this button and draw lines by dragging to mark the areas you want to remove from the picture.
Lines you draw will be indicated with a minus label (see Figure 7) -- again diagonal lines work better than horizontal or vertical lines. You can always undo your last few markings by pressing the
Ctrl+Z keyboard shortcut.
Figure 7: Plus and minus labeled lines indicate the areas to be retained and removed respectively
- Delete Mark: If you need to remove any of the plus or minus lines, click the Delete Mark button, and click
on the line to remove it completely.
You will see how the Refine options influence the selection -- all areas to be removed have a magenta overlay that is updated
dynamically, as shown in Figure 8, below.

- Now, you can either abandon your selections, or remove the background:
- If you want to start all over again or abandon the Background Removal process, click the Discard Changes button within
the Close group in the Background Removal tab.
- If you want to go ahead with the Background Removal, click the Keep Changes button in the Background Removal tab of the
Ribbon. Alternatively, you can click anywhere on the slide outside the picture area to remove all magenta areas of the selected picture
In the example on the left in Figure 9, you can see the picture with only the sky area removed, and towards the right, you
can see the same picture with everything removed except the man. Compare it with Figure 1 above and see the difference.
