How to Export PDF UA Format Documents in C#

In this tutorial, we explore how to export PDF/UA-compliant documents using Iron PDF in C#. The process begins with installing Iron PDF through the NuGet package manager, followed by setting up the IronPDF library in the Program.cs file. After adding the IronPDF license key, the tutorial demonstrates how to load an existing PDF file (e.g., Wikipedia.pdf) using the FromFile method. The key operation involves using the SaveAsPdfUA method to convert and save the document as a PDF/UA-compliant file. The tutorial concludes by running the program and validating the output PDF to ensure compliance. This step-by-step guide is ideal for developers looking to leverage Iron PDF's functionality in C# for creating accessible PDF documents. For those new to Iron PDF, the tutorial encourages trying out the software with a provided download link.

Here's a walkthrough of the necessary code implementation:

// Import the IronPDF library
using IronPdf;

class Program
{
    static void Main(string[] args)
    {
        // Define the path to the PDF file you want to load
        string pdfPath = "Wikipedia.pdf";

        // Load the existing PDF file
        PdfDocument pdfDocument = PdfDocument.FromFile(pdfPath);

        // Check the loading status for debugging purposes
        if (pdfDocument != null)
        {
            Console.WriteLine("PDF loaded successfully.");
        }

        // Define the path to save the PDF/UA compliant document
        string pdfUaPath = "Wikipedia_PDFUA.pdf";

        // Convert and save the existing PDF as a PDF/UA compliant document
        pdfDocument.SaveAsPdfUA(pdfUaPath);

        // Confirm the PDF has been saved
        Console.WriteLine($"PDF/UA compliant document saved at: {pdfUaPath}");
    }
}

// Import the IronPDF library
using IronPdf;

class Program
{
    static void Main(string[] args)
    {
        // Define the path to the PDF file you want to load
        string pdfPath = "Wikipedia.pdf";

        // Load the existing PDF file
        PdfDocument pdfDocument = PdfDocument.FromFile(pdfPath);

        // Check the loading status for debugging purposes
        if (pdfDocument != null)
        {
            Console.WriteLine("PDF loaded successfully.");
        }

        // Define the path to save the PDF/UA compliant document
        string pdfUaPath = "Wikipedia_PDFUA.pdf";

        // Convert and save the existing PDF as a PDF/UA compliant document
        pdfDocument.SaveAsPdfUA(pdfUaPath);

        // Confirm the PDF has been saved
        Console.WriteLine($"PDF/UA compliant document saved at: {pdfUaPath}");
    }
}

' Import the IronPDF library
