To add an Alpha channel, go to the Layer menu, select Transparency, and click on Add Alpha Channel.

Selecting Background with Fuzzy Select

Once you have the Fuzzy Select Tool activated, click on a solid color area of the background you wish to remove.

Adjust the Threshold setting, which you can find in the lower-left corner of your screen in the tool options.

Increase the number to expand the selection to more similar colors, or decrease it to make the selection more precise.

Deleting the Selected Area

After adjusting and finalizing your selection, simply press the Delete key.

Save your edited image as a PNG.

Note that the Fuzzy Select Tool is ideal for images with solid color backgrounds or when the background and the subject have high contrast.

It might require adjustments and multiple attempts to perfect the background removal, especially around detailed edges like hair or fur.

Foreground Select Tool

Outlining the Foreground

Start by roughly selecting the object you want to extract. Make sure to include a bit of the background around it.

Using the Brush Tool

Once your initial selection is outlined, press Enter or double-click inside the selection to create the mask.

Now, switch the mouse pointer to a Paintbrush icon. It’s time to refine your selection by drawing over the foreground. Use the brush tool to paint over the areas you want to keep, ensuring not to include background colors.

Paths Tool

Creating a Path

To start creating a path in GIMP, select the Path tool from the toolbox, which resembles a fountain pen next to a line with three dots.

Continue adding points by clicking along the edges of the subject you wish to isolate.

For more precise control over the shape, right-click on the image, select “Select,” and choose “To Path” to automatically generate points around your selection.

Converting Path to Selection

Once your path is complete, you can convert this path into a selection. This is done by using the “Select->From Path” command, which creates a selection from the active path, typically the last path you’ve created or edited.

If your path is not closed, GIMP will automatically connect the endpoints with a straight line, leaving the original path unchanged. To access this command, you can either use the keyboard shortcut Shift + V or click on the “Path to Selection” button in the Path dialog.
