A family of Microsoft presentation graphics products that offer tools for creating presentations and adding graphic effects like multimedia objects and special effects with text.
The legacy pixel-level background removal editor in PowerPoint has been replaced by the newer AI-based Remove Background experience. In current Microsoft 365 builds (including PowerPoint for Mac), that older tool is no longer available and cannot be re-enabled from within the app.
The current workflow on Mac is:
- Select the picture.
- Go to Picture Format > Remove Background.
- PowerPoint automatically detects the background (magenta area).
- Use Mark Areas to Keep and Mark Areas to Remove with the free-form pencil to refine the result.
- Choose Keep Changes when finished.
This newer tool supports free-form drawing for keep/remove regions, but it does not provide true pixel-by-pixel erasing like the previous implementation. There is no supported setting or toggle in the documented Mac builds to restore the old pixel-level eraser.
For scenarios that require precise pixel editing, the documented guidance is to use an external image editor (for example, the Microsoft Photos app or another dedicated graphics tool), save the image with transparency (such as PNG), and then insert it back into PowerPoint.
