Build A YouTube Video Downloader Using Python GUI

Downloading YouTube videos directly from your desktop might sound complicated, but by following few steps you can create your own YouTube Video Downloader using Python Tkinter.

Using Python’s tkinter library for the graphical user interface and <strong><a href="https://github.com/Josh-XT/pytube2">pytube</a></strong> to handle the video downloads, you can build a fully functional YouTube downloader that looks clean and works efficiently.

Libraries You Will Need

We’ll use two main libraries:
Tkinter : The standard GUI library that comes built-in with Python
Pytube : A lightweight Python library used to download YouTube videos.

To install pytube, run the following command in your terminal:

<strong>pip install pytube</strong>

Logic Behind the Downloading YouTube Videos

This GUI app will allow you to:

Enter a YouTube video link.
Click a button to download the video.
Automatically save the video to your system.

You can later improve it to include quality options, download progress, or audio-only download.

Complete Code: YouTube Video Downloader Using Python

from tkinter import *
from pytube import YouTube
from tkinter import messagebox

# Function to download the video
def download_video():
    try:
        url = url_entry.get()
        yt = YouTube(url)
        stream = yt.streams.get_highest_resolution()
        stream.download()
        messagebox.showinfo("Success", "Download Completed!")
    except Exception as e:
        messagebox.showerror("Error", f"Something went wrong:\n{e}")

# Create GUI window
root = Tk()
root.title("YouTube Video Downloader")
root.geometry("400x200")
root.resizable(False, False)

# Add widgets
title_label = Label(root, text="Enter YouTube Video URL", font=("Arial", 14))
title_label.pack(pady=10)

url_entry = Entry(root, width=50, font=("Arial", 12))
url_entry.pack(pady=5)

download_btn = Button(root, text="Download", font=("Arial", 12), bg="#FF0000", fg="white", command=download_video)
download_btn.pack(pady=20)

# Start the GUI event loop
root.mainloop()

Flow for Code:

A small window opens where you paste a YouTube link. When you click Download, it takes the link and finds the video.
It grabs the highest quality video available. Then it saves it to your computer and shows a success message (or error if failed).

In short, Code Logic and How to run it?

a)_GUI Creation: The app window is built using Tkinter. It has a title, an input field for the URL, and a download button.

b) Downloading: When the user clicks the “Download” button, the app fetches the video from the link using pytube.

c) Stream Handling: We select the highest resolution available and download it.
d) Feedback: A success or error popup appears using messagebox.

The downloaded video will be saved to the same folder where your Python file is located. You can modify the stream.download() call to set a specific path.

Common Issues & Fixes

i) URL not working?: Double-check the URL. Some shortened URLs or age-restricted videos might fail.

ii) Video not downloading?: Make sure pytube is up-to-date: cssCopyEditpip install pytube --upgrade

iii) Slow download?: This depends on your internet connection and the video file size.

Conclusion

Building a YouTube Video Downloader using Python and Tkinter is a fantastic beginner project that introduces you to GUI development, external libraries, and internet tools—all in one package.

The best part? It’s fully customizable. Once you get the basics working, you can continue to improve and personalize it based on your needs.
