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.

// Import necessary namespaces
using System;
using System.Web.UI;
using IronPdf;

namespace aspxtopdf
{
    public partial class SiteMaster : MasterPage
    {
        // The Page_Load event is triggered when the page is loaded
        protected void Page_Load(object sender, EventArgs e)
        {
            // Use IronPDF to render the current ASPX page as a PDF
            AspxToPdf.RenderThisPageAsPdf();
        }
    }
}

// Import necessary namespaces
using System;
using System.Web.UI;
using IronPdf;

namespace aspxtopdf
{
    public partial class SiteMaster : MasterPage
    {
        // The Page_Load event is triggered when the page is loaded
        protected void Page_Load(object sender, EventArgs e)
        {
            // Use IronPDF to render the current ASPX page as a PDF
            AspxToPdf.RenderThisPageAsPdf();
        }
    }
}

' Import necessary namespaces
Imports System
Imports System.Web.UI
Imports IronPdf

Namespace aspxtopdf
	Partial Public Class SiteMaster
		Inherits MasterPage

		' The Page_Load event is triggered when the page is loaded
		Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
			' Use IronPDF to render the current ASPX page as a PDF
			AspxToPdf.RenderThisPageAsPdf()
		End Sub
	End Class
End Namespace

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