Convert ASPX to PDF

Developers often use ASP.NET (ASPX) websites to generate dynamic PDF files such as forms, receipts, or managerial reports for customers to download. While this process can be complicated, the IronPDF library can demonstrate how to convert ASPX to PDF in just one line.

Convert ASPX File PDF

• Install the IronPDF C# PDF Library
• Convert ASPX to PDF with 1 line of code
• Compare the website to PDF render output example

Step 1

1. Install the IronPDF C# Library

First, let's access the free development C# Library for converting ASPX files to PDF. You can download directly or access via NuGet. Install as usual into your Visual Studio project.

Install-Package IronPdf

2. Convert ASPX to PDF

Convert

Now that you have IronPDF, you'll see that it has the functionality for HTML conversion as well as ASPX to PDF generation. We keep it simple, just one line of code, so engineers at any level are able to use it.

We can convert ASPX pages to either our own developed webpage or any website which is developed on ASP.NET.

Let's see an example. We'll use the method “RenderThisPageasPdf()” to cleanly convert the current page to PDF without any issues.

/**
Convert ASPX to PDF
anchor-convert-aspx-to-pdf
**/
using System;
using System.Web.UI;
using IronPdf;

namespace aspxtopdf
{
    public partial class SiteMaster : MasterPage
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            AspxToPdf.RenderThisPageAsPdf();
        }
    }
}

/**
Convert ASPX to PDF
anchor-convert-aspx-to-pdf
**/
using System;
using System.Web.UI;
using IronPdf;

namespace aspxtopdf
{
    public partial class SiteMaster : MasterPage
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            AspxToPdf.RenderThisPageAsPdf();
        }
    }
}

'''Convert ASPX to PDF

Imports System
Imports System.Web.UI
Imports IronPdf

Namespace aspxtopdf
	Partial Public Class SiteMaster
		Inherits MasterPage

		Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
			AspxToPdf.RenderThisPageAsPdf()
		End Sub
	End Class
End Namespace

IronPDF offers developers methods to render PDF documents into images and extract text and content from a PDF. Additionally, IronPDF is also capable of rendering charts in PDFs, adding barcodes using the IronBarcode library, enhancing security with passwords and watermarking programmatically.

3. View Rendered Output

Using C#, IronPDF offers an option to automate and create PDF documents.

In this example, this dummy ASPX website is used to convert the ASPX file to PDF. You can directly compare the output file, and how closely the PDF result matches the original website. This kind of high-quality rendering is unique to IronPDF and especially valuable when working with clients.
