How Can I Increase The Resolution Of My Icon In My GUI Window?

Question

I have been doing lots of little tasks in Python to continue learning it and I got to GUIs In python via this code:

from tkinter import * 

count = 0

def click(): 
    global count 
    count += 1
    print("You have clicked the button "+str(count)+" Times")

Window = Tk()

Photo = PhotoImage(file="Pig2.png")

Like_Button = PhotoImage(file="Like-Button2.png")

Window.geometry("600x600")

Window.title("The Ultimate GUI Program")

Icon = PhotoImage(file="AngryBird.png")

Window.iconphoto(True,Icon)

button = Button(Window,
                text="Click me",
                command=click,
                font=("Comic Sans,",10,"bold"),
                fg="Red",
                bg="black",
                activeforeground="Red",
                activebackground="black",
                image=Like_Button,
                compound="bottom") 

button.place(x=50,y=50) 


Window.config(background="white") 

Label = Label(Window, 
              text="You are using the best program ever!", 
              font=("Arial",10,"bold"),
              fg="red",
              bg="white",relief=RAISED,bd=10,
              padx=10,
              pady=10,image=Photo,
              compound="bottom")


Label.place(x=170,y=170) # -Placing the image in a specifed place 

Window.mainloop() # - Displays the window on the computer screen

However when using this code to create this a very simple GUI program it makes my icon in the corner of the window very pixelated compared to the icon in the taskbar.

How can I fix this?

My Image dimensions are 50 X 50 and the format of the file is png

Here is what my program looks like:

Here is what it looks like on the taskbar:

I have to fill in the part saying what I tried however except for trying to look up how to fix this I don't know what else to try myself.
