This post will introduce the IronPDF for Python module to convert an existing PDF file to a PDFA file.

How to Convert PDF to PDFA in Python

Download the Python PDF Library to convert PDF to PDF/A in Python.
Create a New Python Project in PyCharm or any other IDE.
Load an existing PDF file using PdfDocument.FromFile method.
Convert PDF to PDFA using SaveAsPdfA method.
Run the project to get the converted PDFA file.

IronPDF

Compared to other languages, Python provides significantly greater dynamism for programmers and enables developers to rapidly and easily create graphical user interfaces. Therefore, incorporating the IronPDF library into Python is a straightforward process. A wide range of pre-installed tools, such as PyQt, wxWidgets, Kivy, and various other packages and libraries, can be utilized to efficiently and securely assemble a fully functional GUI.

Python web design and development are greatly simplified with the aid of IronPDF. This is primarily attributed to the abundance of Python web development paradigms available, including Django, Flask, and Pyramid. Websites and online services like Reddit, Mozilla, and Spotify have successfully employed these frameworks.

IronPDF allows users to inspect and annotate PDF files.
Images can be extracted from documents using IronPDF.
With IronPDF, it is very easy to add headers, footers, text, pictures, bookmarks, watermarks, and more to documents.
Users can combine and split pages within a new or existing document using IronPDF.
Conversion of documents to PDF objects is possible without relying on an Acrobat viewer.
IronPDF allows the creation of a PDF document from a CSS file.
CSS files with media-type specifications can be used to construct documents with IronPDF.

Configure Python Environment

Setup Python

Ensure that Python is installed on your computer. Visit the official Python website to download and install the latest version of Python suitable for your operating system. Once Python is installed, create a virtual environment to isolate the requirements for your project. Utilize the venv module to create and manage virtual environments, providing a clean and separate workspace for your conversion project.

New Project in PyCharm

For this tutorial, PyCharm, an IDE for Python development, is recommended. Download and install PyCharm from the official website.

After launching the PyCharm IDE, select "New Project" from the menu, as shown in the figure below.

IronPDF Library Requirement

IronPDF in Python utilizes .NET. Therefore, it is necessary to have the .NET Runtime installed on your machine in order to use IronPDF for Python. This comes pre-installed on Windows, but Linux and Mac users may need to install .NET before using this Python package.

IronPDF Library Setup

In order to be able to generate, modify, and open files with the ".pdf" extension, the ironpdf package must be installed. Open a terminal window and enter the following command to install the package in PyCharm:

 pip install ironpdf

The ironpdf package has been installed, as shown in the screenshot below.

Creating PDF/A from PDF Document

With the assistance of the IronPDF library, creating a PDF/A document is a straightforward process. These files are designed to store information for long-term preservation. Below is an example code snippet for converting a PDF file to a PDF/A file:

from ironpdf import PdfDocument, PdfAVersions

# Load an existing PDF file
pdf = PdfDocument.FromFile("sample.pdf")

# Save it as a PDF/A file, specifying the desired version
pdf.SaveAsPdfA("Converted_pdfa.pdf", PdfAVersions.PdfA3)

from ironpdf import PdfDocument, PdfAVersions

# Load an existing PDF file
pdf = PdfDocument.FromFile("sample.pdf")

# Save it as a PDF/A file, specifying the desired version
pdf.SaveAsPdfA("Converted_pdfa.pdf", PdfAVersions.PdfA3)

PYTHON

The above code demonstrates how to convert PDF files to PDF/A format using just a few lines of Python code with the assistance of IronPDF. In the initial step, we import the necessary classes from the IronPDF library, which allows access to all the features provided by IronPDF, particularly through the PdfDocument class.

By using the FromFile method, the input PDF file is loaded by specifying its file path as a parameter. The PdfDocument object provides the SaveAsPdfA method, which allows you to save and convert the PDF file into the PDF/A format. The SaveAsPdfA method requires two parameters: the new save file location and the PDF/A version. The PDF/A version parameter is optional, and if not specified, it will default to PdfAVersions.PdfA3.
