Python to Convert JPEG to PNG with Source Code

This project contains a simply python script to change the file extension from .jpeg to .png


Pillow module

pip install pillow

Two methods:

I accomplished this task in two ways

Using Terminal:

  • Add the image in jpeg format with name as ‘input’ in this folder.
  • Run script
  • output image will be generated in this folder

Using GUI:

Just run the script and pick any jpeg image from any location and then press ‘Convert Jpeg to Png’

Source Code:


from PIL import Image
im1 ='input.jpeg')  # takes input image from present folder'output.png')          # output image is generated the folder



import tkinter as tk from tkinter import filedialog from PIL import Image root = tk.Tk() # Tkinter window initialized root.title('Converter') # Title of the window canvas1 = tk.Canvas(root, width=300, height=250, bg='orange', relief='raised') canvas1.pack() label1 = tk.Label(root, text='File Converter', bg='lightsteelblue2') # giving a title to the screen label1.config(font=('helvetica', 20)) canvas1.create_window(150, 60, window=label1) im1 = None # variable to store path of image def getJPG(): '''Function to get image location and open it with pillow''' global im1 import_file_path = filedialog.askopenfilename() im1 = font = ('helvetica', 12, 'bold') bg = 'royalblue' fg = 'white' browseButton_JPG = tk.Button(text=" Import JPEG File ", command=getJPG, bg=bg, fg=fg, font=font) # Browse button canvas1.create_window(150, 130, window=browseButton_JPG) def convertToPNG(): '''Function to change file extenstion to png and save it to User's prefered location ''' global im1 if im1 is None: tk.messagebox.showerror("Error", "No File selected") else: export_file_path = filedialog.asksaveasfilename(defaultextension='.png') saveAsButton_PNG = tk.Button(text='Convert JPEG to PNG', command=convertToPNG, bg=bg, fg=fg, font=font) # Convert button canvas1.create_window(150, 180, window=saveAsButton_PNG) root.mainloop()
