How to Remove Image Background in GIMP using the Fuzzy Select Tool

The Fuzzy Select or the Magic Wand tool is one of the most used tools to remove background in GIMP. It removes areas that have a color similar to the selected areas. It helps if the background and the subject have contrasting colors. Also, the task will be easier if the foreground has sharp edges.

Launch the GIMP application. Open the image from which you want to remove background by selecting File > Open in the upper left corner. You will see the image in the editor window.

To add Alpha Channel, right-click on the image, and select Layer > Transparency > Add Alpha Channel.

Now, you can use the Fuzzy Select tool. Select Tools (in the upper menu) > Selection Tools > Fuzzy Select, or press U on your keyboard. Or, you can select the Fuzzy Select tool icon from the tool panel.

Select Tools > Selection Tools > Fuzzy Select

Select the background by clicking on the background color.

How Does GIMP Remove Background Using The Paths Tool

If you are working with complex backgrounds, you can use the Paths tool to trace the outline of the object. When you create a path using a dotted outline around it, you can use curves and straight lines for precision. The edge selecting process may be time consuming, but believe us, the results will be amazing. Here is how to remove the background from a picture using the Paths tool.

Open GIMP and open your image. Add the Alpha Channel as in the previous method. Next, open the Path tool by selecting Tools > Paths.

Select Tools > Paths
Select Tools > Paths

Start with any point at the edge of the subject and click on the next point to make a straight line. You can also click and drag to make curved lines. Proceeding in this way, make an outline of the subject. Finally, press enter to make a selection.

You can invert the selection by navigating to the Select menu > Invert. Here, we have extended the outline to manually select the background instead of using the Invert option. Next, press the Delete key to remove the background. If you don’t add the Alpha Channel, the final image will have a white background, as in the image below.

Remove Background from Image in GIMP Using the Select By Color Tool

From the name, it is easy to guess that the Select By Color tool can remove background in GIMP by selecting the color to be removed. Like the Fuzzy Selection tool, you can click on a color pixel, and it will choose the adjacent areas with the same color or shades for deletion. Our image perfectly shows how the single dark blue color of the background can be easily removed by the Select By Color tool.

Launch the GIMP app and open the desired image in the image editor. Add the Alpha Channel and choose the tool by selecting Tools > Selection Tools > By Select Color. You can also select the tool by pressing Shift + O.

Select Tools > Selection Tools > By Select Color
Select Tools > Selection Tools > By Select Color

Click anywhere on the background color, and the area around it with the same color will be selected.

How to Remove Background from Image in GIMP using the Foreground Select Tool

The Foreground Select Tool is used to remove background in GIMP by indicating what the foreground object is. You can use this tool if the object has finer detail, like hair or fur. For example, you can draw a crude outline to distinguish the foreground from background and then use a mask layer.

Open the GIMP software, open the image, and add the Alpha Channel.

Select Tools > Selection Tools > Foreground Select.

Layer mask is one of the best tools for image manipulations. It can be used to remove background in GIMP by modifying the layer transparency. This is done by adjusting the colors of the background and foreground to make them distinct.

Open the GIMP app and open the image. Add the Alpha Channel. On the layers menu, right-click on the image near the Eye button and select “Add Layer Mask”.

Final Thoughts

It is easy to remove backgrounds with distinctive color differences. But here, you can remove background in GIMP neatly even if there are feathered edges or similar shades in the subject. There are no complicated methods; the tools are easy to use if you follow the detailed instructions.

Some of the tools are apt if the background has a single color while others do not ask for a solid color background. You can also use a combination of tools if you feel that one tool does not give satisfactory results.
