How To Merge PDF Files in Python

We’ll use the PyPDF2 python module for pdf manipulation. So first, We’ll install this into the python application.

Install pypdf2 in python

To use the PyPDF2 library in Python, We need to first install PyPDF2. Run the below code to install the PyPDF2 module in the system.

pip install PyPDF2

How To Combine PDF Files In Python

The below python script help to merge two pdf files into one file.

import PyPDF2

def main():
	# pdf files to merge
	all_files = ['first.pdf', 'second.pdf']

	# output pdf file name
	output_file = 'combined.pdf'

	# merge object
	pdfMerger = PyPDF2.PdfFileMerger()

	for pdf in all_files:
		pdfMerger.append(pdf)

	# writing combined pdf to output file
	with open(output_file, 'wb') as f:
		pdfMerger.write(f)

if __name__ == "__main__":
	# calling the main function
	main()

The above code will combine first.pdf and second.pdf file output into the new pdf(combined.pdf) file.

Let’s have a look at some of the program’s key features:

• Step 1: Define all pdf files that we need to merge.
• Step 2: Define output files that ll hold all pdf files content after merge.
• Step 3: We create an object pdfMerger of pdf merger class Using PdfFileMerger.
• Step 4: Iterate on all pdf list and append file object of each pdf to pdf merger object using append() method.
• Step 5: Finally, We’ll write the pdf pages to the output pdf(combined.pdf) file using write method of pdf merger object.
