PythonでPDFをPDFAに変換する方法

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.

Configure Python Environment

 pip install ironpdf

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)

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.

The output PDF file

In the output, both the source file and the created PDF/A file are displayed. However, the watermark can be removed by using the licensed version of the software. For more detailed tutorials and information, you can click on the following tutorial for HTML to PDF converter.
