Extract text from PDF File using Python

All of you must be familiar with what PDFs are. In fact, they are one of the most important and widely used digital media. PDF stands for Portable Document Format. It uses .pdf extension. It is used to present and exchange documents reliably, independent of software, hardware, or operating system.

We will extract text from pdf files using two Python libraries, pypdf and PyMuPDF, in this article. 

Extracting text from a PDF file using the pypdf library.

Python package pypdf can be used to achieve what we want (text extraction), although it can do more than what we need. This package can also be used to generate, decrypting and merging PDF files. Note: For more information, refer to Working with PDF files in Python

Installation

To install this package type the below command in the terminal.

pip install pypdf

Example:Input PDF:👁 extract-pdf-text-python

Output:

👁 extract-pdf-python

Let us try to understand the above code in chunks:

reader = PdfReader('example.pdf')

• We created an object of PdfReader class from the pypdf module.
• The PdfReader class takes a required positional argument of the path to the pdf file.

print(len(reader.pages))

• pages property gives a List of PageObjects. So, here we can use the in-built len() function of python to get the number of pages in the pdf file.

page = reader.pages[0]

• Now, as reader.pages is a list of PageObjects, we can get a specific Page of the pdf by tapping into the index of the page. In python list indexing starts from 0, so reader.pages[0] gives us the first page of the pdf file.

text = page.extract_text()
print(text)

• Page object has function extract_text() to extract text from the pdf page.

Extracting text from a PDF file using the PyMuPDF library.

PyMuPDF is a Python library that supports file formats like XPS, PDF, CBR, and CBZ. But for now, in this article, we are going to concentrate on PDF (Portable Document Format) files.

Installation

pip install pymupdf
pip install fitz

To extract the text from the pdf, we need to follow the following steps:

1. Importing the library
2. Opening document
3. Extracting text

Note: We are using the sample.pdf here; to get the pdf, use the link below.  

sample.pdf - Link

1. Importing the library

2. Opening document

Here we created an object called "doc," and filename should be a Python string.

3. Extracting text

Here, we iterated pages in pdf and used the get_text() method to extract each page from the file.

Conclusion

We have seen two Python libraries, pypdf and PyMuPDF, that can extract text from a PDF file. Comment on your preferred library from the above two libraries.
