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.

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

To install the ironpdf package necessary to create, edit, and open PDF files, start by opening a terminal in PyCharm and run the following command:

 pip install ironpdf

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.

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 PdfDocument

# Load the PDF document from a specified file path
pdf = PdfDocument.FromFile('F:\\PDF\\EditorDemo.pdf')

# Call the Flatten method to remove all form fields and controls
pdf.Flatten()

# Save the flattened PDF to a new file
pdf.SaveAs("flattenpdf.pdf")

from ironpdf import PdfDocument

# Load the PDF document from a specified file path
pdf = PdfDocument.FromFile('F:\\PDF\\EditorDemo.pdf')

# Call the Flatten method to remove all form fields and controls
pdf.Flatten()

# Save the flattened PDF to a new file
pdf.SaveAs("flattenpdf.pdf")

PYTHON

This example begins by importing the ironpdf module, setting the stage to utilize its functionalities for PDF operations. Using PdfDocument.FromFile(), it loads an existing PDF file, allowing various manipulations. The Flatten() method is called to remove interactive elements like form fields, converting them into a static part of the PDF content. Finally, SaveAs() is used to save the modified PDF to a new file, thus completing the flattening process.
