Python 3 Tkinter Script to Build Screenshot Capture Desktop App Using Pillow Module

Welcome folks today in this blog post we will be building a screenshot capture desktop app in python using pillow module. All the full source code of the application is shown below.

Get Started

In order to get started you need to install the below libraries using the pip command as shown below

pip install pillow

Now we need to make an app.py file and copy paste the following code

app.py

import tkinter as tk
from tkinter import filedialog
from PIL import ImageGrab

# Create a Tkinter root window
root = tk.Tk()


# Create a button to trigger the screenshot function
screenshot_button = tk.Button(text="Take Screenshot", command=take_screenshot)
screenshot_button.pack()

# Run the Tkinter event loop
root.mainloop()

import tkinter as tk

from tkinter import filedialog

from PIL import ImageGrab

# Create a Tkinter root window

root = tk.Tk()

# Create a button to trigger the screenshot function

screenshot_button = tk.Button(text="Take Screenshot", command=take_screenshot)

screenshot_button.pack()

# Run the Tkinter event loop

root.mainloop()

As you can see we are importing the tkinter and pillow module and then we have the button to take the screenshot of the window and save it as png image.

Now we will be writing the function which will execute when we hit the take screenshot button to take the full screenshot and save it as png image file

# Function to take a screenshot and save it to a file
def take_screenshot():
    # Ask the user to select a file to save the screenshot to
    file_path = filedialog.asksaveasfilename(defaultextension=".png")
    if file_path:
        # Use ImageGrab to capture the screen and save the image to the file
        ImageGrab.grab().save(file_path)

# Function to take a screenshot and save it to a file

def take_screenshot():

# Ask the user to select a file to save the screenshot to

file_path = filedialog.asksaveasfilename(defaultextension=".png")

if file_path:

# Use ImageGrab to capture the screen and save the image to the file

ImageGrab.grab().save(file_path)

As you can see in the above code we are using the filedialog module and inside it we are asking the user to save the screenshot at a specified location and inside it we are providing the default extension for the image which is .png and then we are capturing the screenshot using the pillow module and we are using the grab() method and then we are using the save() method to save the image file at the specified location.
