Ideally, you’d want to make all similar colors transparent as well.įor example, the color of the shirt in my image is white, but there’s many different grayscale shades that need to be made transparent as well, otherwise the shirt wont be entirely transparent. Seeing as how nuanced the color composition of images can be, chances are you don’t just want to make a single color transparent. Step 3: Set the farthest full-transparency color

Alternatively, you can also click on the white stripe to manually input a color code if you prefer to do it that way.įor this example image I will be making the shirt color transparent, so I clicked on the area of the image where the shirt is. With the dropper selected, click on the area of your image that contains the color you’d like to make transparent. It’s the first item at the top of the list, located next to the white stripe: The dropper icon to select is highlighted in red. To pick the color that you’d like to make transparent in GIMP, click on the dropper icon in the Color to Alpha menu labelled “ pick color from the image” when you hover your cursor over it.
Step 2: Pick the color that you’d like to make transparent Lighter areas become more transparent, whereas darker areas remain more opaque. The reason why this happens is because by default, the Color field in the Color to Alpha menu is white (as indicated by the white stripe in the menu.) This means that the white portion of all of the colors in your image are reduced to transparency based on a scale of how much white the color contains. Once opened, you should notice that a large portion of the image on your canvas becomes partially transparent: Your image may look something like this when you first open the Color to Alpha menu. To access this menu, navigate to Colors > Color to Alpha.
