Welcome folks today in this post we will be merging images to pdf document using pypdf2 library in python. All the full source code of application is shown below.

Get Started

First of all you need to install the following library using the pip command as shown below

pip install pypdf2

In order to get started you need to make an app.py file and copy paste the following code

app.py

from tkinter import *
from tkinter import filedialog
from PIL import ImageTk, Image
from PyPDF2 import PdfFileWriter, PdfFileReader

img_list = []
root = Tk()
root.title('Opening files')


def open_file():
    global page
    root.filename = filedialog.askopenfilenames(initialdir=".s",
                                                title="Select a file",
                                                filetypes=(
                                                ("PNG Files", "*.png"),
                                                ("All files", "*.*")))

    file_list = list(root.filename)

    for name in file_list:
        page = Image.open(name)
        page = page.convert("RGB")
        img_list.append(page)
        my_label = Label(text=name).pack()


def generate_pdf():
    global page
    global img_list
    page.save(r"Gone with the Blastwave.pdf", save_all=True,
              append_images=img_list)

    print(img_list)


# def stop():
#   exit()


my_button = Button(root, text="Add file", command=open_file).pack()
my_button2 = Button(root, text="Generate PDF", command=generate_pdf).pack()
my_button3 = Button(root, text="Cancel", command=exit).pack()
root.mainloop()


pages_to_delete = [0]  # page numbering starts from 0
infile = PdfFileReader('New_File.pdf', 'rb')
output = PdfFileWriter()

for i in range(infile.getNumPages()):
    if i not in pages_to_delete:
        p = infile.getPage(i)
        output.addPage(p)

with open('New_File.pdf', 'wb') as f:
    output.write(f)

Now if you execute the python script by typing the below command as shown below

python app.py
