There are many ways to remove a white background using Photoshop. Assuming the outlines of the image are fairly clear cut, one of the easiest ways is to use the “Magic Wand Tool.”
Before using the tool though, the user will need to adjust the layers. If a white background is going to be removed, it needs a transparent background to replace it. First select the Background layer and rename it. Create a new layer (Ctrl / Command + Shift + N) and make sure the color is set to “None.”
In the Layers menu, move the newly created layer underneath the one with the white background. Use the Magic Wand Tool to select the white background and delete.
