Image to PDF in python with GUI using Tkinter – Tutorial

Here in this tutorial, we are going to create a desktop application “using Python Tkinter” which can convert any Image(JPG or PNG) to PDF formatted file.
Let’s create Image to PDF in python with GUI by following these simple steps.

Requirements to get started

You will need PIL/Pillow (python library) to open, read and converting images. Run these commands in terminal to install Pillow

For Mac and Linux

pip3 install Pillow

For windows

py -m pip install Pillow

Finished?
After you finish this, we can follow the next steps.

Python function to convert Image to PDF encoding.

First of all let’s define a function to convert image encoding to pdf format.

from PIL import Image
#...
def convert(img_path):
     img = Image.open(img_path)
     try:
         pdf = img.convert('RGB')
         return pdf
     except:
         return False
        

Here, “img_path” is path of the image file and the function will return a PDF(bytes). If you don’t need a GUI, you can use this function to convert the Image file into PDF.

Full code – Image to PDF converter

from PIL import Image
from Tkinter
def convert(img_path):
     img = Image.open(img_path)
     try:
         pdf = img.convert('RGB')
         return pdf
     except:
         return False

def button_click():
     image_path = filedialog.askopenfilename(filetypes=['Image Files', '.png', '.jpg'])
     pdf = convert(image_path)
     if pdf:
         file_path = filedialog.asksaveasfilename(filetypes=['PDF Files', '*.pdf']) +'.pdf'
         pdf.save(file_path)
         messagebox.showinfo('Saved', f'Your PDF is saved at\n{file_path}')
     else:
         messagebox.showerror('Error', 'An error Occured while converting file')
 GUI
 app = filedialog.Tk()
 app.title('PDF Converter')
 button = ttk.Button(app, text='Select & Convert', command=button_click)
 button.place(relx=0.5, rely=0.5, anchor='center')
 app.mainloop()

Result – Image to PDF
