How to Flatten a PDF File in Python

There are scenarios where it is needed to flatten a PDF, which means removing these interactive elements and converting them into a static, non-editable format. In Python, it is possible to achieve this using the IronPDF library. This article will delve into how to flatten a PDF file using IronPDF.

IronPDF

Python is a computer language that helps programmers design graphical user interfaces quickly and easily. Python is also a lot more dynamic for programmers than other languages. As a result, introducing the IronPDF library to Python is a straightforward procedure. To quickly and safely develop a fully functional GUI, a wide range of pre-installed tools, including PyQt, wxWidgets, Kivy, and many other packages and libraries, can be used. We may incorporate a number of features from other frameworks, such as .NET Core, using IronPDF, which does not only support Python. Click here to learn more about Python IronPDF.

IronPDF makes Python web design and development simpler. Django, Flask, and Pyramid are three Python web development paradigms that have seen broad acceptance as a result. Just a handful of the websites and online services that have used these frameworks include Reddit, Mozilla, and Spotify.

IronPDF Features

• The creation of PDF documents from a variety of sources, including HTML, HTML5, ASPX, and Razor/MVC View, is possible with IronPDF. It provides the option to create PDF files from HTML pages and images.
• The IronPDF toolkit can assist with a variety of tasks, including creating interactive PDFs, finishing and submitting interactive forms, split and combine PDF files, extracting text and images, searching text within PDF files, rasterizing PDFs to images, changing font sizes, and converting PDF files.
• With support for user-agents, proxies, cookies, HTTP headers, and form variables, IronPDF provides HTML login form validation.
• Usernames and passwords are used by IronPDF to grant users access to documents that are secured.
• IronPDF can print a PDF file from a number of sources, such as a string, stream, or URL, with just a few lines of code.

With the help of IronPDF, it becomes easy to generate flattened PDF documents.

Setup Python

Environment Configuration

Check that Python is installed on your PC. Visit the official Python website to download and install the most recent version of Python that is compatible with your operating system. Once Python is installed, segregate the requirements for your project by creating a virtual environment. The venv module lets you create and manage virtual environments to provide your conversion project a neat, separate workspace.

New Initiative in PyCharm

PyCharm is recommended as an IDE for writing Python code, for this tutorial.

Select "New Project" once the PyCharm IDE has launched.

Create a New Project in PyCharm

When you select "New Project," a new window will open where you can specify the project's environment and location. The image below may help you see this.

Specify the project environment and location

Click the Create button to start a New Project after selecting the Project location and environment path. The software can then be built in the subsequent new window that appears. This tutorial makes use of Python 3.9.

IronPDF Library Requirement

IronPDF for Python, mostly makes use of .NET 6.0. As a result, in order to utilize IronPDF for Python, your computer 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. To obtain the required runtime environment, go to this download page from Microsoft.

IronPDF Library Installation

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

The screenshot below displays the installation of the ironpdf package.

Generate Flattened PDF using IronPDF

Flattening a PDF can be easily done with the help of IronPDF with just a few lines of code. Below is the source PDF which has text boxes form with a calendar control as a sample PDF file.

Source PDF containing a form with calendar and text box controls

In the PDF form which has three fields, which include two text boxes and one calendar control. It also contains some form field values. Below is the sample code.

from ironpdf import *

pdf = PdfDocument.FromFile('F:\\PDF\\EditorDemo.pdf')
pdf.Flatten()
pdf.SaveAs("flattenpdf.pdf")

from ironpdf import *

pdf = PdfDocument.FromFile('F:\\PDF\\EditorDemo.pdf')
pdf.Flatten()
pdf.SaveAs("flattenpdf.pdf")

The first line of code in the above code example imports the IronPDF library, allowing us to use all its features. Then the PdfDocument class is used to load the existing PDF document to perform various types of operations like merge PDFs, extracting text, images, etc., with the help of the available methods in the PdfDocument class. Now the Flatten method is used to flatten a PDF file. This function removes all the fields present in the PDF form such as the text boxes and calendar control, and the PDF file size drops. At last, the SaveAs() method is used to save the generated flattened PDF document into the desired location.
