Creating Images with Transparent Background

This section provides a tutorial example on how to create an image with transparent background with GIMP by add the Alpha Channel and removing the solid background color.

To test this out, let's create an image with transparent background with GIMP first.

1. Click menu File > New to create a new image with a size of 144 x 144 pixels.

2. Click menu Layer > Transparency > Add Alpha Channel. In order to have a transparent background, an image must have the Alpha Channel added. Of course, you can remove the Alpha Channel, if you don't want the transparent background.

3. Click menu Select > All. The current solid background color is selected. By default, GIMP always creates new images with a solid background color, white.

4. Click menu Edit > Clear. The selected solid background color is deleted. You see a checkerbox pattern on the entire image indicating that there is no other elements on the image except the transparent background.

5. Now add the English text "PEACE" and the Chinese text "和平" on the image.

6. Save the image with name, GIMP_Peace_Transparent.gif, and format, GIF. We have a GIF image with transparent background created now.
