Are you looking for a way to make your Tkinter GUIs stand out? One way to add some visual appeal is by incorporating PNG images with transparency. With transparent backgrounds, you can create buttons and graphics that appear to float above your GUI’s interface. But, if you’ve tried using PNGs with Tkinter, you may have noticed that they don’t always display correctly. Don’t worry; we’ve got you covered with our step-by-step guide to enabling PNG transparency in Tkinter.

There’s no need to settle for plain, flat buttons when you can add some depth and dimension with PNG transparency. Our guide walks you through each step of the process, so even if you’ve never worked with Tkinter or image files before, you’ll be able to follow along. We’ll cover the basics of PNG images, how to install the necessary libraries, and how to modify your Tkinter code to allow for transparency.

By the end of our guide, you’ll be ready to create eye-catching, professional-looking GUIs that will impress your users. Say goodbye to dull and unappealing interfaces and hello to a world of possibilities with Tkinter’s PNG transparency. What are you waiting for? Dive into our guide today!

“How Do I Make Tkinter Support Png Transparency?” ~ bbaz


Tkinter is a module in Python that allows users to create GUI applications. One of its main features is the support for adding images, including PNG, to the interface. However, by default, Tkinter does not support transparency in PNG images. This can be limiting when creating designs and interfaces that require transparent backgrounds for the images. In this article, we’ll explore a step-by-step guide on how to enable PNG transparency in Tkinter.

What is PNG Transparency?

PNG transparency is the ability to make parts of an image transparent, allowing the background color or image to show through. This is often used in logos and icons when the user wants the image to blend in or stand out against a background. The transparency is achieved by using alpha channels, which store information about the image’s transparency levels.

The Default Behavior of Tkinter with PNG Images

When using PNG images in Tkinter, the default behavior is to ignore any alpha channels in the image and replace them with a solid color. This is because Tkinter uses the PhotoImage class to add images, which does not support transparency by default. As a result, any transparent parts of the image will be replaced with the image’s background color.

Why Enable PNG Transparency in Tkinter?

There are several reasons why you might want to enable PNG transparency in Tkinter. One of the most common is for designing GUIs with dynamic backgrounds, such as animations or video players. By enabling PNG transparency, you can make sure that your images will blend seamlessly into the interface, regardless of the background color or image. Additionally, it allows you to create more complex designs and interfaces, as you can layer images with transparency on top of each other, creating a more dynamic and professional look.

Step-by-Step Guide to Enabling PNG Transparency in Tkinter

Step One: Installing Pillow

The first step in enabling PNG transparency in Tkinter is to install the Python Imaging Library, or PIL. While this module is no longer maintained, it has a fork called Pillow, which is backwards-compatible with PIL and has more functionality. To install Pillow, you can use pip by entering the following command into your terminal:

pip install pillow

Step Two: Importing the Image Module from Pillow

Once you have installed Pillow, you need to import the Image module into your Python code. This will allow you to use the features of PIL with Tkinter. Here’s how to import it:

from PIL import Image

Step Three: Creating a PhotoImage Object from an RGBA Image

The next step is to create a PhotoImage object from an RGBA image. This is an image that contains an alpha channel and is necessary for transparency to work. You can create an RGBA image using the open() method from the Image module, like this:

img =

Step Four: Creating a Tkinter Compatible Image Object

Now that you have your RGBA image object, you need to create a Tkinter-compatible image object. To do this, you’ll create a new PhotoImage object and use the RGBA image as the data source. Here’s how:

photo = ImageTk.PhotoImage(img)

Step Five: Adding the Image to a Tkinter Widget

Finally, you can add the image to a Tkinter widget by using a label or canvas. Here’s an example using a label:

label = tk.Label(image=photo) # Replace tk with your tkinter namespace

Comparing Tkinter with and without PNG Transparency

There are several differences between using Tkinter with and without PNG transparency. Here are some of the main ones:


One of the most noticeable differences is the appearance of the images. With transparency enabled, the images have more depth and can be layered on top of each other. Without transparency, the images appear flat and can only be stacked horizontally or vertically.

File Size

Another difference is the file size of the images. When transparency is enabled, the images can be saved as PNG files, which are usually smaller in size than other image formats, such as BMP or TIFF. This can be an advantage when creating large interfaces or animations that require many images to be loaded.

CPU Load

Add transparency to images may increase the CPU Load of your application. When enabling transparency, the computer must do additional processing to determine what to display in the transparent portions. This can increase the CPU load of your application, especially if you are working with a large number of images or complex animations.

Final Thoughts

Enabling PNG transparency in Tkinter allows you to create more complex and dynamic interfaces with seamless image integration. While there are some drawbacks, such as increased CPU load, the benefits of improved appearance and file size make it worth considering for your GUI application. With the step-by-step guide we’ve provided, you can easily enable PNG transparency in your Tkinter projects and take your designs to the next level.
