Convert ASPX to PDF

As developers, we often use ASP.NET (ASPX) websites to generate dynamic PDF files such as forms, receipts, or managerial reports for customers to download as a PDF. While this process can be a complicated string of code on its own, today we'll use the IronPDF library to show how to convert ASPX to PDF in just one line.

Code Examples

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();
		}
	}
}
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

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.

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();
        }
    }
}
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

3. View Rendered Output

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

In our example, we used a dummy ASPX website to convert the ASPX file to PDF. You can directly compare the output file, 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.
