Paint 3D is a photo-editing tool that allows users to crop images into various shapes. While the software does not support direct cropping of non-rectangular shapes, it is possible to crop a circle or any other 2D shape with a few workarounds. This involves using the 2D shape tool to draw the desired shape on the image and then cropping and erasing the excess parts of the image. The cropped image can then be saved in the PNG format to retain transparency. Additionally, Paint 3D offers features such as Magic Select and Select in 3D to easily select and cut out objects from pictures.
| Characteristics | Values |
|---|---|
| Cropping a circle shape | Draw a circle on the image by selecting the circle from the 2D shapes at the top. Then, adjust the crop selection so that it touches the inner edges of the circle. |
| Removing the background | Click on the Brushes icon and select the eraser. Erase the extra part by dragging the mouse over the outer areas. |
| Making the background transparent | Save the image in PNG format to retain transparency. |
| Cropping non-rectangular shapes | While you cannot directly crop non-rectangular shapes, you can use the above workaround to crop a circle. |
| Keyboard shortcuts | Hold down the Shift key while dragging a corner handle to maintain the aspect ratio, or press Enter after clicking the Crop icon in the minimized sidebar. |

How to crop a circle in Paint 3D
To crop a circle in Paint 3D, follow these steps:
- Open your image file in Paint 3D.
- Use the 2D shapes function to draw a circle around the target. Ensure that the ''Fill' is set to 'None' and the 'Line type' is 'Solid' with sufficient thickness. Adjust the circle so that the inner boundary covers the target fully.
- Once you are happy with the circle, crop the image using a 1:1 aspect ratio, up to the outer edge of the circle.
- Everything outside the circle should now be cleared.
- To crop the image further down to the object boundary, use the ''Magic Select' function and click 'Next'. Paint 3D will automatically detect the edge of the object and crop away everything else.
- If the automatic crop is not accurate, you can refine the cutout by manually adding or removing sections.
- Finally, separate the image from the cropped section by clicking 'Done'.
By following these steps, you can crop a circle in Paint 3D without the need for advanced editing software.

Using the Magic Select tool
Paint 3D's Magic Select tool is a simple, free tool that can be used to edit 2D photos. It works best with simple, well-lit objects that have clear distinctions between them. To use the tool, open your image with the "Edit with Paint 3D" shortcut, which will take you into the 2D editing tool. Size your photo to fill the screen, then use the Magic Select tool to choose the object you want to remove. If you remove a person or object from the scene, Magic Select will fill in the background that was behind it. When you're happy with your selection, drag the object off the canvas into the 3D virtual space next to it. From there, you can cut and paste your edited object into a new image. Keep in mind that Magic Select may struggle with complex images and lighting effects, so it's best to keep it simple. If you need to retrace your steps, use the Undo or History tool in the upper-right corner.
