How to Merge PDF File using Python?

Hi Guys,

I am going to show you how to merge pdf files using python. We will talk about merging multiple pdfs into a single pdf using a python script.

Have you ever had multiple pdf files that you need to merge into one single document? It is easier than you might think to merge or combine two or more pdf into one single file in python.

PyPDF2 is a python library used to work with PDF files. You can use it to extract document information, split document page by page, merge multiple pages, encrypt and decrypt, etc. In this tutorial, you will learn how to merge multiple files using this module.

Step 1 :

You first need to install the package using pip:

pip install PyPDF2

Step 2 : Python Script

#import PyPDF2 Package

import PyPDF2


# Open the files that have to be merged one by one

pdf1File = open('/var/www/samplepdf1.pdf', 'rb')

pdf2File = open('/var/www/samplepdf2.pdf', 'rb')

# Read the files that you have opened

pdf1Reader = PyPDF2.PdfFileReader(pdf1File,strict=False)

pdf2Reader = PyPDF2.PdfFileReader(pdf2File,strict=False)

# Create a new PdfFileWriter object which represents a blank PDF document

pdfWriter = PyPDF2.PdfFileWriter()

# Loop through all the pagenumbers for the first document

for pageNum in range(pdf1Reader.numPages):

pageObj = pdf1Reader.getPage(pageNum)


# Loop through all the pagenumbers for the second document

for pageNum in range(pdf2Reader.numPages):

pageObj = pdf2Reader.getPage(pageNum)


# Now that you have copied all the pages in both the documents, write them into the a new document

pdfOutputFile = open('var/www/mergeSample.pdf', 'wb')


# Close all the files - Created as well as opened
