I previously wrote a blog post about removing backgrounds. Click the link below; the article dates back to March 2016, when PowerPoint 2013 was the current version.
The underlying concept hasn't changed much in PPT 2024.
However, it appears that in PowerPoint 365 though, Microsoft is replacing the manual background removal tool with a new AI-powered image editor. Consequently, the options to Mark areas to keep or remove may no longer be available.
For now, you can still add them by clicking the down arrow of the Quick Access Toolbar, under 'Choose commands from' select More Commands, and then choose All Commands.
Scroll down and select Remove Background. Click the Add button, then click OK. The classic Remove Background tool will be added to the right side of the Quick Access Toolbar.
The old tool is still available in PPT 2024. You cannot remove the background from:
- vector images (SVG, EMF, WMF),
- images set as slide backgrounds,
- animated GIFs (only the first frame is processed).
If you still want to use a vector image, you must first export it to the PNG graphic format.
For testing purposes, I used two photos via the Insert - Image - Stock Images option. One of the photos (Statue of Liberty) has a rather complex background.
This is the result after accepting the changes:
After making adjustments using the correction tools, you get the following result, though it requires a few modifications.
The background of the second photo appears somewhat simpler.
This is the result after accepting the changes:
After correction, it looks like this:
Alternative: using the Windows 11 Photos app
Launch the Photos app, which you can easily find in the Start menu.
Select the photo and click the Edit button:
Click the Background button and select Remove background. Note the shaded areas of the photo; these parts will be removed.
You can use the background brush to add to or remove from the mask. The shaded lines now show the resulting effect.
With the second photo, the result using the Photos app is much better right away, requiring very little correction.
The results therefore depend heavily on the chosen photo. The more uniform the background, the better the result.
