Sometimes you may want to make image background transparent when you merge two or more pictures into one. On Windows computers, you can combine photos together using Microsoft Paint which is bundled with the Windows OS. It however doesn’t fully support transparency. Although you can change the picture format in Microsoft Paint, the output image still has white background when you save it as PNG files. Since Windows 10, we can find a redesigned version of the classic Paint app which is called Paint 3D. This image editor can help us easily turn white background transparent or make background of images transparent.
You can find the Paint 3D from Windows Start menu or do a search in the search box from Windows taskbar at your screen bottom. Launch Paint 3D in Windows 10, the Welcome Screen shows up. Choose New to create a new project in Paint 3D. The Brushes tab opens by default. Switch to the Canvas tab from the top toolbar. Turn on Transparent Canvas from the right pane. See below screenshot.
After that, click to expand the main Menu, choose Insert to add your photo to the image editor. Your photo will be put above the transparent canvas. Now we need to select the object you like to keep and remove the rest part, its background or background color. Click Select button, press and hold, then drag to select a rectangular area. If the object you want to keep is not rectangular, click Magic select, drag in the corners or sides of the blue box to focus on the object you want to keep.
Press Next button to refine your cutout or selection. You can mark any unselected areas to add them to your cutout and/or mark unwanted areas to remove them from your cutout. Click Done button, the selected object will be extracted from its background.
Now the object is separately from its background. They are now two independent layers above the canvas. To remove background from image or make background of images transparent, you can simply click to select the background layer, then click the Delete button from the Edit section in the right pane to remove image background.
To create a new photo with transparent, click the Menu button from the top left corner, choose Save as, select PNG as the file format, enable Transparency option before you save it to your computer.
