How to Parse A PDF File in Python
1.0 Introduction
Modern libraries have streamlined PDF creation. When choosing a library for PDF projects, consider build, read, and conversion capabilities for optimal integration and performance. Python offers tools like IronPDF that can efficiently parse existing PDFs.
2.0 IronPDF
Python is a programming language that enables developers to quickly and easily construct graphical user interfaces. It offers greater dynamism for programmers compared to other languages. Therefore, integrating the IronPDF library with Python is a straightforward process.
To rapidly and securely build a fully functional GUI, developers can utilize several pre-installed tools, including PyQt, wxWidgets, Kivy, and many other packages and libraries. It is worth noting that IronPDF is not a pure Python PDF library; instead, it allows the inclusion of various features from other frameworks like .NET Core.
IronPDF simplifies Python web design and development, particularly due to the popularity of Python web development paradigms such as Django, Flask, and Pyramid. Notable websites and online services, including Reddit, Mozilla, and Spotify, have utilized these frameworks. You can learn more about Python in IronPDF on the IronPDF for Python website.
2.1 Features of IronPDF
- IronPDF is capable of generating PDF files from various sources, including HTML, HTML5, ASPX, and Razor/MVC View. It provides functionality to create PDFs from HTML pages and images.
- The IronPDF toolkit offers a range of tools for tasks such as creating interactive PDFs, filling and submitting interactive forms, split and combine PDF files, extract text and images from PDF files, search for certain words within a PDF file, rasterize PDF pages to images, convert PDF to HTML.
- With support for user-agents, proxies, cookies, HTTP headers, and shape variables, IronPDF allows HTML login form validation.
- Access to protected documents in IronPDF is granted through the use of usernames and passwords.
- IronPDF helps generate PDF files and print with just a few lines of code from various sources like strings, streams, URLs, etc.
3.0 Setup Python
3.1 Environment Setup
Ensure that Python is installed on your PC. Visit the official Python website to download and install the latest version of Python suitable for your operating system. Once Python is installed, set up a virtual environment to isolate the dependencies for your project. Use the "venv" module to create and manage virtual environments, providing your conversion project with a clean and independent workspace.
3.2 New Project in PyCharm
We're going to use PyCharm, an IDE for writing Python code, for this demonstration.
Click "New Project" after launching the PyCharm IDE.
The PyCharm welcome screen
When you select "New Project", a new window will emerge, allowing you to specify the project's location and its environment. This new window can be seen in the screenshot below.

Click the Create button to start a new project, after setting the Project location and environment path. This will open a new window where the program can be developed. This tutorial recommended Python 3.9.

3.3 IronPDF Library Requirement
IronPDF, a Python library, relies primarily on .NET 6.0. As a result, to make use of IronPDF for Python, your PC has to have the .NET 6.0 runtime installed. Before Linux and Mac users may use this Python module, .NET may need to be installed. You can obtain the required runtime environment from the .NET website.
3.4 IronPDF Library Setup
The "ironpdf" package needs to be installed in order to create, edit, and open files with the ".pdf" extension. To install the package in PyCharm, open a terminal window and type the following command:
pip install ironpdf
pip install ironpdf
The screenshot underneath shows the setup of the 'ironpdf' package.

4.0 Parse PDF with IronPDF
With the assistance of the IronPDF libraries, it is possible to extract text from PDF files. IronPDF provides various techniques for text extraction. The first approach involves retrieving all the content on the page as a single string. The second approach involves reading the content page by page, starting from the first page. The following code snippet demonstrates a pattern for inspecting current PDF files using IronPDF.
There are two methods available to extract data from a PDF:
- Extracting from the PDF by page.
- Extracting the whole PDF as text.
Below is the PDF file which we're going to use for this article. It has two pages.
A PDF with the page number at the top of each page
4.0.1 TEXT EXTRACTION BY PAGES
The sample code provided below demonstrates how to use the page number to retrieve data from a PDF file.
from ironpdf import PdfDocument
# Open a PDF file and create a PDF document object
pdfDocument = PdfDocument.FromFile("F:\\PDF\\1.pdf")
# Extract text from the first page (index 0)
AllText = pdfDocument.ExtractTextFromPage(0)
# Print the extracted text from the first page
print(AllText)
from ironpdf import PdfDocument
# Open a PDF file and create a PDF document object
pdfDocument = PdfDocument.FromFile("F:\\PDF\\1.pdf")
# Extract text from the first page (index 0)
AllText = pdfDocument.ExtractTextFromPage(0)
# Print the extracted text from the first page
print(AllText)
The code snippet demonstrates the usage of the FromFile
function to read a PDF file and create a PDF document object. This object allows access to texts and images within the PDF. To extract the text from a particular page, the ExtractTextFromPage
method can be used by providing the page number as a parameter. This method will return a string containing all the words on the specified page. The output will be displayed as below.
A screenshot of the terminal with text output "Page 1"
The rectangle box which highlighted in the result is the data extracted text from the PDF file on the page number 1, which has the index as 0.
4.0.2 EXTRACT FROM ALL PAGE
The first approach to quickly and easily obtain all the PDF content as a string is shown in the code example that follows.
from ironpdf import PdfDocument
# Create a PDF file object from the file path
pdf = PdfDocument.FromFile('F:\\PDF\\1.pdf')
# Extract all text from the entire PDF
all_text = pdf.ExtractAllText()
# Print the extracted text from the entire PDF
print(all_text)
from ironpdf import PdfDocument
# Create a PDF file object from the file path
pdf = PdfDocument.FromFile('F:\\PDF\\1.pdf')
# Extract all text from the entire PDF
all_text = pdf.ExtractAllText()
# Print the extracted text from the entire PDF
print(all_text)
The example code shown above explains how to read a PDF from an existing file path and turn it into a PDF file object using the FromFile
function. The PDF's plain text will be extracted and converted into a string using the object's ExtractAllText
function and it will print the extracted text on the terminal. The result will be shown like below.
A screenshot of the terminal with text output "Page 1", and "Page 2"
The rectangle boxes which are highlighted in the result contain the data extracted text from all the pages of the PDF file.
We are able to create PDFs using C# with the help of IronPDF. To learn more about IronPDF, visit the IronPDF website.
