6 GIMP Remove Background Method:

Each of the methods is for particular image types. Before using any of the processes, you must examine and determine the style of the image first.

Method 1 – Using the color tool:

This one is the easiest among all other methods. This one is best suited for images with a single-colored background.  When you click on a single color on the picture, this tool will select all the pixels to consist of that specific color.

To access the tool, press Shift + O and then pick the color you want to remove. All the pixels will get selected. You can now delete or change the background according to your need.

This method is an easy process to remove a single color from any image. Remember, the technique will not work as expected if the background consists of a gradient or multiple shades.

Method 2 – Using Fuzzy Select Tool:

This method nicely removes the background from an Image in GIMP. Fuzzy select tool replicates the work of magic wand tool in Adobe Photoshop. 

For removing the background using the Fuzzy Select tool, use the following steps:

  1. Open the image in GIMP. Go to File on the top, and click open.

The shortcut for opening an image file is Ctrl + O. 

  • Select the Fuzzy Select tool; the icon appears as a magic wand. You can select the tool by pressing U on the keyboard.
  • Click and drag around the subject to make a selection.
  • Add to your selection by pressing and holding Shift and then clicking the areas you want to include
  • Remove unwanted selection by holding Ctrl on the keyboard and clicking on the portions
  • After you see the overall selection, make sure if it requires any other tweaking
  • If the selection is from the background, click delete on the keyboard to remove the background
  • If the selection is on the subject, go to Select and choose Invert. Now press delete

This GIMP delete selection method works very fine if you are good at making the selection.

The perfect coordination between adding and removing selections makes the whole process much faster and smoother.

Method 3 – Using Path Tool:

This method is a bit more advanced. This one is the best and professional way to get GIMP transparent background. Using the Path tool requires some previous skills and consumes more time.

This process creates the cleanest and more professional result. Path tools have pretty much the same working procedure as pen tools in Adobe Photoshop. You can manually place smooth lines and curves on the border of the subject.

Follow the process :

  1. Open or import the image to GIMP
  2. Select the path tool. The shortcut is B.
  3. Make a selection around the subject’s outline
  4. After completing the selection, the subject got selected. For removing the background, you have to invert (Ctrl + I) the section and then click delete on the keyboard.

If there are many other colors involved in the image, selecting the subject, using the Fuzzy Select tool or Color tool becomes challenging. This method helps to set the issue manually and create a cleaner look.

This GIMP cut out image background works very nicely.
