By | January 6, 2022

In this tutorial, we will introduce how to use python pypdf2 library to split a large pdf file to a small one by pages.

Preliminary

We should install python pypdf2 first.

pip install pypdf2

Read a pdf file using pypdf2

Here is an example:

from PyPDF2 import PdfFileReader, PdfFileWriter

pdf_input = r'2022010614181218.pdf'
pdf = PdfFileReader(pdf_input)

Get pages you wanted from source pdf

Here is an example:

pdf_writer = PdfFileWriter()
output_filename =  "fengyijun.pdf"

for page in range(2, 3):
    pdf_writer.addPage(pdf.getPage(page))

In this example, we will create a PdfFileWriter instance to save pages you want to extract from source pdf.

You shoud notice: the page index starts from 0, which means the first page = 0, the second page = 1.

This example we will extract the third page from 2022010614181218.pdf to save a new pdf.

Save pages to new pdf

Finally, we can save pages extracted from source pdf to a new pdf file.

with open(output_filename, 'wb') as out:
    pdf_writer.write(out)
