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.
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 the IronPDF Package or access via NuGet. Install as usual into your Visual Studio project.
# Install the IronPDF package via NuGet
nuget install IronPdf
# Install the IronPDF package via NuGet
nuget install IronPdf

2. Convert ASPX to PDF

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.
