How to Extract Metadata From PDF Files Using Python?

Well, if you are a techie (even if you are not) using Python language you can take out the metadata of any PDF. All you have to do is to install the pyPDF2 package.

Let’s see how you can achieve this-

The PDF sample used here is called “reportlab-sample.pdf”.

Here’s the code:

# get_doc_info.py

from PyPDF2 import PdfFileReader

def get_info(path):
with open(path, ‘rb’) as f:
pdf = PdfFileReader(f)
info = pdf.getDocumentInfo()
number_of_pages = pdf.getNumPages()

print(info)

author = info.author
creator = info.creator
producer = info.producer
subject = info.subject
title = info.title

if __name__ == ‘__main__’:
path = ‘reportlab-sample.pdf’
get_info(path)

As you can see, we have imported the PdfFileReader class from PyPDF2. This class can read a PDF and extract data from it. Next, we create our get_info function that will take a PDF file path as its argument. Then we will open the file in read-only binary mode. Finally, we pass that file handler into “PdfFileReader” and create an instance out of it.

We can use the getDocumentInfo method for how to extract metadata from PDF. It will return an instance of PyPDF2.pdf.DocumentInformation, which will have useful attributes like author, creator, producer, subject, and title.
