In supported desktop versions of PowerPoint, select at least two shapes, open Shape Format → Merge Shapes, and choose an operation to create a new shape from their geometry. Use Union for one solid silhouette, Combine for a cutout, Fragment for separate regions, Intersect for only the overlap, or Subtract to cut one shape from another.
Selection order matters especially for Subtract: the first-selected shape is the one retained, and the later-selected shape is the cutter. The result remains an editable PowerPoint shape; it is not automatically converted to a picture.
What merging shapes means in PowerPoint
Merge Shapes is a geometry tool for making custom shapes from standard PowerPoint shapes. For example, you can subtract one circle from another to make a crescent, use Combine to make a hole, or use Intersect to create a lens-shaped region. The result can generally be moved, filled, outlined, resized, and refined with Edit Points.
Merging is different from grouping. A merge changes the geometry into a new shape or set of regions; a group keeps the original objects separate but lets you manipulate them together.

Prerequisites and best practices
- Use actual PowerPoint shapes: pictures and other object types do not behave like standard shapes in Merge Shapes. Grouped objects may need to be ungrouped first.
- Position shapes deliberately: overlap is necessary for useful Intersect and Subtract results. Union can also combine shapes that do not overlap.
- Choose the base shape first for Subtract: the first-selected shape is retained and the later-selected shape cuts it.
- Keep an original copy: duplicate the source shapes before merging if you may need to adjust their individual geometry later.
For a first test, insert a circle and another shape, overlap them, and try each operation before applying it to a complex design.
Method 1 (Most common): Merge Shapes with Shape Format
Microsoft lists Merge Shapes for supported desktop editions including PowerPoint for Microsoft 365, PowerPoint 2024, 2021, 2019, and 2016, with corresponding Mac editions where listed. The command appears when qualifying shapes are selected.
Windows
- Choose Insert → Shapes, select a shape, and click and drag on the slide to draw it. Repeat for the other shapes.
- Arrange the shapes so their overlap produces the result you want.
- Hold Ctrl and click each shape to select them, or drag a selection box around unobstructed shapes.
- Open Shape Format.
- In the Insert Shapes group, choose Merge Shapes.
- Select Union, Combine, Fragment, Intersect, or Subtract.
macOS
- Choose Insert → Shapes and draw the shapes you need.
- Arrange the shapes with the intended overlap.
- Hold Shift and select each shape.
- Open Shape Format, choose Merge Shapes, and select an operation.
PowerPoint for the web
Microsoft’s Merge Shapes support page lists desktop editions, not PowerPoint for the web. If the command is unavailable in your browser, open the presentation in a supported desktop app and merge the shapes there.
How each merge option changes the result
Use two overlapping shapes to compare the operations. The choice determines whether the output is one silhouette, a cutout, or several regions.
| Option | Result | Typical use |
|---|---|---|
| Union | One solid shape covering the combined outer area; the internal boundary disappears. | Joining shapes into one silhouette or icon |
| Combine | One shape with the overlapping area removed. | Holes, rings, cutouts, or stencil effects |
| Fragment | Separate selectable regions divided by the original shapes’ boundaries. | Splitting a shape into pieces that can be formatted separately |
| Intersect | Only the common overlapping area remains. | Lens shapes or precise overlap regions |
| Subtract | The later-selected shape removes its overlapping area from the first-selected shape. | Crescents, notches, and other cutouts |
For example, select a large circle first and an offset smaller circle second, then choose Subtract to cut the smaller circle’s overlap from the large one. If you select them in the opposite order, the result can be very different. To recover, undo, deselect, and select the intended base shape first.
Creating clean new objects after merging
Inspect the geometry before applying elaborate styling. Formatting may not carry over exactly from every selected shape, so apply the final fill, outline, transparency, or effects to the merged result.
Manage fill, outline, and transparency
- Merge the shapes and inspect the result.
- Use Shape Fill and Shape Outline on Shape Format to set the appearance you want.
- Add or adjust transparency and effects afterward, and remove unwanted shadows or other effects if they make the edges look wrong.
Formatting behavior can vary with the selected shapes and PowerPoint version; do not assume every original fill, outline, gradient, or effect will be preserved exactly.
Reorder, align, and select covered shapes
Align and position source shapes before merging. If a shape is covered and difficult to select, use Home → Select → Selection Pane to find and select it, or temporarily move a top shape out of the way. The Selection Pane can also help identify and reorder objects.

Group or ungroup after the merge
Fragment can create multiple regions. If you want the resulting objects to move together, select them and group them; grouping does not merge their geometry. Ungrouping a group keeps its component objects separate again.
Editing merged shapes
A merged result remains a PowerPoint shape that can generally be adjusted with Edit Points. Edit the outline before applying elaborate fills or effects, which can make points harder to see.
- Select the merged shape.
- Choose Shape Format → Edit Shape → Edit Points.
- Drag the black points to reshape the outline; use the white square points to adjust curves between points.
Edit Points is useful when a corner needs adjustment, the outline is close but not exact, or you need a contour the five merge operations cannot create on their own.
Saving and reusing a custom shape
To reuse a custom result in another Office document, right-click the shape, choose Save as Picture, and save it. Insert the saved file elsewhere with Insert → Pictures. Saving as a picture makes that saved copy an image rather than an editable PowerPoint shape, so keep the presentation file if you still need to edit its points.

Fix: The Merge Shapes button is missing or grayed out
- Select at least two qualifying shapes; the command may be unavailable when the selection does not contain shapes.
- Check that you selected shapes rather than a picture, chart, text box, or group. Ungroup components first if needed.
- Confirm that Shape Format appears, then look for Merge Shapes in the Insert Shapes group.
- If you are using PowerPoint for the web, try a supported desktop version.
Fix: You can’t select the intended shapes
- Use Home → Select → Selection Pane to select objects by name, including covered objects.
- Temporarily move a top object away, select the intended shapes, then restore its position if you have not merged yet.
- On Windows, hold Ctrl while selecting each shape; on Mac, hold Shift.
Fix: Subtract cut in the wrong direction
Undo with Ctrl+Z on Windows or Command+Z on Mac. Deselect the shapes, select the shape to retain first and the cutter afterward, then apply Subtract again. Selection order—not simply the shapes’ front-to-back position—is the key instruction to follow.
Fix: The result has unexpected holes or regions
Check that you chose the intended operation: Combine removes overlap, while Union removes internal boundaries and creates one solid silhouette. Inspect the overlap and selection order, and try merging fewer shapes at a time. Fragment is useful when you want separate regions; Edit Points can refine the resulting outline.
Fix: Colors or outlines look wrong
Apply the desired fill and outline to the result after merging. Remove and reapply effects if they create unwanted edges. With Fragment, remember that the output may contain several separate objects.

If you need to keep components independently editable, group them rather than merging. For a one-off slide visual, layered shapes and background-colored overlays can imitate a cutout, but this is not true geometric subtraction and may break if the background changes.
For advanced vector editing, a vector editor can provide boolean operations. Check that the exported or imported result suits your workflow before relying on it as an editable PowerPoint shape.
FAQ
Does Group merge shapes?
No. Group keeps objects separate but lets you manipulate them together. Merge Shapes changes their geometry and creates a new shape or separate regions.
Which shape should I select first for Subtract?
Select the shape you want to retain first, then select the shape that should cut it. If the result is wrong, undo and repeat with the intended base shape selected first.
Can I merge more than two shapes?
Yes, you can select multiple shapes, but the result can become harder to predict as geometry gets more complex. Try the operation with two shapes first or merge incrementally.

Can I edit a merged shape afterward?
Generally, yes. Select it and use Shape Format → Edit Shape → Edit Points to adjust its outline. Keep a copy of the original shapes if you may need to change their individual geometry.
Can I use Merge Shapes in PowerPoint for the web?
Microsoft’s support page lists desktop editions for this feature, not the web version. If the command is unavailable in the browser, use a supported desktop edition.
Does Save as Picture keep the shape editable?
No. The saved copy is an image. Keep the PowerPoint presentation if you need to continue editing the merged shape’s points.
