How to Convert a Webpage to PDF in ASP.NET

Curtis Chau

Updated:

Converting web pages to PDF in ASP.NET is straightforward with IronPDF's ChromePdfRenderer class, which transforms HTML strings, URLs, and ASPX pages into high-quality PDF documents using just a few lines of C# code.

When you need to generate downloadable reports, invoices, or archival documents in an ASP.NET application, converting web content to PDF is one of the most common requirements. IronPDF gives you a direct path to convert a webpage to PDF in ASP.NET, handling everything from simple HTML strings to fully rendered dynamic web pages -- without requiring any third-party browser installations or complex configuration.

This guide walks through the primary conversion methods available in IronPDF, from basic HTML string rendering to URL-based page capture and ASP.NET Web Forms integration. By the end, you'll have working C# code for each scenario and a clear understanding of when to use each approach.

How Do You Install and Set Up IronPDF?

Before converting any content, install IronPDF into your ASP.NET project. The library is distributed via NuGet and works with .NET 6, .NET 8, .NET 10, and .NET Framework:

Install-Package IronPdf
dotnet add package IronPdf
Install-Package IronPdf
dotnet add package IronPdf
SHELL

After installation, add the namespace at the top of your C# file:

using IronPdf;
using IronPdf;
Imports IronPdf
$vbLabelText   $csharpLabel

IronPDF works with both ASP.NET Web Forms and ASP.NET Core applications. It supports Windows Server and IIS deployments, Docker containerization, Azure Functions, and AWS Lambda for cloud-native architectures. Review the installation overview for platform-specific setup details and Linux deployment instructions.

How Do You Convert an HTML String to PDF?

The ChromePdfRenderer class is the main entry point for PDF generation in IronPDF. When you have HTML content as a string -- whether generated dynamically or loaded from a template -- the RenderHtmlAsPdf method converts it directly to a PDF document.

This approach is ideal for generating reports, invoices, and receipts where you construct the HTML programmatically from database records or application data. The renderer processes the HTML using the same Chromium-based engine that powers modern browsers, so CSS layouts, web fonts, and standard HTML5 elements all render correctly.

using IronPdf;

var renderer = new ChromePdfRenderer();

string htmlContent = @"
    <h1>Quarterly Sales Report</h1>
    <p>Q3 2025 -- Summary of key revenue metrics and product performance.</p>
    <table>
        <thead><tr><th>Product</th><th>Units</th><th>Revenue</th></tr></thead>
        <tbody>
            <tr><td>Widget A</td><td>320</td><td>$8,960</td></tr>
            <tr><td>Widget B</td><td>150</td><td>$6,750</td></tr>
            <tr><td>Widget C</td><td>210</td><td>$3,055.30</td></tr>
        </tbody>
    </table>";

var pdf = renderer.RenderHtmlAsPdf(htmlContent);
pdf.SaveAs("quarterly-report.pdf");
using IronPdf;

var renderer = new ChromePdfRenderer();

string htmlContent = @"
    <h1>Quarterly Sales Report</h1>
    <p>Q3 2025 -- Summary of key revenue metrics and product performance.</p>
    <table>
        <thead><tr><th>Product</th><th>Units</th><th>Revenue</th></tr></thead>
        <tbody>
            <tr><td>Widget A</td><td>320</td><td>$8,960</td></tr>
            <tr><td>Widget B</td><td>150</td><td>$6,750</td></tr>
            <tr><td>Widget C</td><td>210</td><td>$3,055.30</td></tr>
        </tbody>
    </table>";

var pdf = renderer.RenderHtmlAsPdf(htmlContent);
pdf.SaveAs("quarterly-report.pdf");
Imports IronPdf

Dim renderer As New ChromePdfRenderer()

Dim htmlContent As String = "
    <h1>Quarterly Sales Report</h1>
    <p>Q3 2025 -- Summary of key revenue metrics and product performance.</p>
    <table>
        <thead><tr><th>Product</th><th>Units</th><th>Revenue</th></tr></thead>
        <tbody>
            <tr><td>Widget A</td><td>320</td><td>$8,960</td></tr>
            <tr><td>Widget B</td><td>150</td><td>$6,750</td></tr>
            <tr><td>Widget C</td><td>210</td><td>$3,055.30</td></tr>
        </tbody>
    </table>"

Dim pdf = renderer.RenderHtmlAsPdf(htmlContent)
pdf.SaveAs("quarterly-report.pdf")

If your HTML references external stylesheets or images using relative paths, provide the base directory as a second argument. This tells IronPDF where to resolve those references:

using IronPdf;

var renderer = new ChromePdfRenderer();

string html = @"
    <link rel='stylesheet' href='styles.css'>
    <h1>Company Report</h1>
    <div>Annual Summary</div>";

// Provide the base path so the renderer can locate relative resources
var pdf = renderer.RenderHtmlAsPdf(html, @"C:\Reports\Assets\");
pdf.SaveAs("annual-report.pdf");
using IronPdf;

var renderer = new ChromePdfRenderer();

string html = @"
    <link rel='stylesheet' href='styles.css'>
    <h1>Company Report</h1>
    <div>Annual Summary</div>";

// Provide the base path so the renderer can locate relative resources
var pdf = renderer.RenderHtmlAsPdf(html, @"C:\Reports\Assets\");
pdf.SaveAs("annual-report.pdf");
Imports IronPdf

Dim renderer As New ChromePdfRenderer()

Dim html As String = "
    <link rel='stylesheet' href='styles.css'>
    <h1>Company Report</h1>
    <div>Annual Summary</div>"

' Provide the base path so the renderer can locate relative resources
Dim pdf = renderer.RenderHtmlAsPdf(html, "C:\Reports\Assets\")
pdf.SaveAs("annual-report.pdf")
$vbLabelText   $csharpLabel

How Do You Convert a URL to PDF?

When you need to capture an existing web page -- whether an internal application route or a public URL -- IronPDF's RenderUrlAsPdf method fetches the full page content and converts it to PDF. The output preserves styles, images, and layout exactly as rendered in a browser.

Rendering a Static Web Page

For pages that serve mostly static content, a basic call to RenderUrlAsPdf is sufficient. The method handles SSL certificates, redirects, and content encoding automatically:

using IronPdf;

var renderer = new ChromePdfRenderer();

// Optional: wait a short time for the page to finish loading
renderer.RenderingOptions.WaitFor.RenderDelay(500);

var pdf = renderer.RenderUrlAsPdf("https://en.wikipedia.org/wiki/PDF");
pdf.SaveAs("wikipedia-pdf-article.pdf");
using IronPdf;

var renderer = new ChromePdfRenderer();

// Optional: wait a short time for the page to finish loading
renderer.RenderingOptions.WaitFor.RenderDelay(500);

var pdf = renderer.RenderUrlAsPdf("https://en.wikipedia.org/wiki/PDF");
pdf.SaveAs("wikipedia-pdf-article.pdf");
Imports IronPdf

Dim renderer = New ChromePdfRenderer()

' Optional: wait a short time for the page to finish loading
renderer.RenderingOptions.WaitFor.RenderDelay(500)

Dim pdf = renderer.RenderUrlAsPdf("https://en.wikipedia.org/wiki/PDF")
pdf.SaveAs("wikipedia-pdf-article.pdf")
$vbLabelText   $csharpLabel

Rendering Pages with JavaScript or Authentication

For pages that require authentication or use JavaScript to load data dynamically, configure the renderer with the appropriate credentials and wait strategy:

using IronPdf;

var renderer = new ChromePdfRenderer();

// Enable JavaScript for pages that load content after the initial HTML response
renderer.RenderingOptions.EnableJavaScript = true;
renderer.RenderingOptions.WaitFor.NetworkIdle(500);

// Provide credentials for authenticated internal pages
renderer.LoginCredentials = new ChromeHttpLoginCredentials()
{
    NetworkUsername = "service-account",
    NetworkPassword = "secure-password"
};

var pdf = renderer.RenderUrlAsPdf("https://app.internal/reports/monthly");
pdf.SaveAs("monthly-report.pdf");
using IronPdf;

var renderer = new ChromePdfRenderer();

// Enable JavaScript for pages that load content after the initial HTML response
renderer.RenderingOptions.EnableJavaScript = true;
renderer.RenderingOptions.WaitFor.NetworkIdle(500);

// Provide credentials for authenticated internal pages
renderer.LoginCredentials = new ChromeHttpLoginCredentials()
{
    NetworkUsername = "service-account",
    NetworkPassword = "secure-password"
};

var pdf = renderer.RenderUrlAsPdf("https://app.internal/reports/monthly");
pdf.SaveAs("monthly-report.pdf");
Imports IronPdf

Dim renderer As New ChromePdfRenderer()

' Enable JavaScript for pages that load content after the initial HTML response
renderer.RenderingOptions.EnableJavaScript = True
renderer.RenderingOptions.WaitFor.NetworkIdle(500)

' Provide credentials for authenticated internal pages
renderer.LoginCredentials = New ChromeHttpLoginCredentials() With {
    .NetworkUsername = "service-account",
    .NetworkPassword = "secure-password"
}

Dim pdf = renderer.RenderUrlAsPdf("https://app.internal/reports/monthly")
pdf.SaveAs("monthly-report.pdf")

How Do You Convert an ASPX Page to PDF in ASP.NET Web Forms?

For ASP.NET Web Forms applications, IronPDF provides the AspxToPdf class that converts the currently rendered ASPX page directly to a PDF -- without requiring a separate HTTP request or re-rendering the page content.

Basic One-Line ASPX Conversion

Call RenderThisPageAsPdf() inside a page event handler, and IronPDF intercepts the response and replaces it with a PDF download:

using IronPdf;

protected void Page_Load(object sender, EventArgs e)
{
    // Configure paper settings before rendering
    IronPdf.AspxToPdf.RenderingOptions.PaperSize = IronPdf.Rendering.PdfPaperSize.Letter;
    IronPdf.AspxToPdf.RenderingOptions.MarginTop = 20;
    IronPdf.AspxToPdf.RenderingOptions.MarginBottom = 20;

    // Convert the current ASPX page to PDF and send it to the browser
    IronPdf.AspxToPdf.RenderThisPageAsPdf(
        IronPdf.AspxToPdf.FileBehavior.InBrowser,
        "invoice-" + DateTime.UtcNow.ToString("yyyy-MM-dd") + ".pdf"
    );
}
using IronPdf;

protected void Page_Load(object sender, EventArgs e)
{
    // Configure paper settings before rendering
    IronPdf.AspxToPdf.RenderingOptions.PaperSize = IronPdf.Rendering.PdfPaperSize.Letter;
    IronPdf.AspxToPdf.RenderingOptions.MarginTop = 20;
    IronPdf.AspxToPdf.RenderingOptions.MarginBottom = 20;

    // Convert the current ASPX page to PDF and send it to the browser
    IronPdf.AspxToPdf.RenderThisPageAsPdf(
        IronPdf.AspxToPdf.FileBehavior.InBrowser,
        "invoice-" + DateTime.UtcNow.ToString("yyyy-MM-dd") + ".pdf"
    );
}
Imports IronPdf

Protected Sub Page_Load(sender As Object, e As EventArgs)
    ' Configure paper settings before rendering
    IronPdf.AspxToPdf.RenderingOptions.PaperSize = IronPdf.Rendering.PdfPaperSize.Letter
    IronPdf.AspxToPdf.RenderingOptions.MarginTop = 20
    IronPdf.AspxToPdf.RenderingOptions.MarginBottom = 20

    ' Convert the current ASPX page to PDF and send it to the browser
    IronPdf.AspxToPdf.RenderThisPageAsPdf(
        IronPdf.AspxToPdf.FileBehavior.InBrowser,
        "invoice-" & DateTime.UtcNow.ToString("yyyy-MM-dd") & ".pdf"
    )
End Sub

How Do You Add Headers and Footers to PDF Documents?

Headers and footers are standard for professional reports and invoices. IronPDF supports both text-based and HTML-based headers and footers, with built-in placeholders for dynamic values like page numbers and the current date.

Text and HTML Headers

The TextHeaderFooter class lets you define simple text on the left, center, and right of each page. Placeholders like {page}, {total-pages}, and {date} are populated automatically during rendering. When you need branded headers with logos and custom layouts, use HtmlHeaderFooter instead -- its HTML fragment is processed by the same rendering engine as the document body:

using IronPdf;

var renderer = new ChromePdfRenderer();

// Simple text header with divider line
renderer.RenderingOptions.TextHeader = new TextHeaderFooter()
{
    CenterText = "Quarterly Financial Report",
    LeftText = "Document ID: {document-id}",
    RightText = "{date:yyyy-MM-dd}",
    DrawDividerLine = true,
    FontSize = 10,
    FontFamily = "Arial"
};

// HTML footer with branded layout
renderer.RenderingOptions.HtmlFooter = new HtmlHeaderFooter()
{
    HtmlFragment = @"
        <div style='border-top: 1px solid #ccc; padding: 8px; font-size: 10px;
                    display: flex; justify-content: space-between;'>
            <span>© 2026 Enterprise Corp</span>
            <span>Page {page} of {total-pages}</span>
            <span>Classification: Internal</span>
        </div>",
    MaxHeight = 40
};

renderer.RenderingOptions.MarginTop = 40;
renderer.RenderingOptions.MarginBottom = 40;

var pdf = renderer.RenderHtmlAsPdf("<h1>Report Content</h1><p>Financial data goes here.</p>");
pdf.SaveAs("report-with-headers.pdf");
using IronPdf;

var renderer = new ChromePdfRenderer();

// Simple text header with divider line
renderer.RenderingOptions.TextHeader = new TextHeaderFooter()
{
    CenterText = "Quarterly Financial Report",
    LeftText = "Document ID: {document-id}",
    RightText = "{date:yyyy-MM-dd}",
    DrawDividerLine = true,
    FontSize = 10,
    FontFamily = "Arial"
};

// HTML footer with branded layout
renderer.RenderingOptions.HtmlFooter = new HtmlHeaderFooter()
{
    HtmlFragment = @"
        <div style='border-top: 1px solid #ccc; padding: 8px; font-size: 10px;
                    display: flex; justify-content: space-between;'>
            <span>© 2026 Enterprise Corp</span>
            <span>Page {page} of {total-pages}</span>
            <span>Classification: Internal</span>
        </div>",
    MaxHeight = 40
};

renderer.RenderingOptions.MarginTop = 40;
renderer.RenderingOptions.MarginBottom = 40;

var pdf = renderer.RenderHtmlAsPdf("<h1>Report Content</h1><p>Financial data goes here.</p>");
pdf.SaveAs("report-with-headers.pdf");
Imports IronPdf

Dim renderer = New ChromePdfRenderer()

' Simple text header with divider line
renderer.RenderingOptions.TextHeader = New TextHeaderFooter() With {
    .CenterText = "Quarterly Financial Report",
    .LeftText = "Document ID: {document-id}",
    .RightText = "{date:yyyy-MM-dd}",
    .DrawDividerLine = True,
    .FontSize = 10,
    .FontFamily = "Arial"
}

' HTML footer with branded layout
renderer.RenderingOptions.HtmlFooter = New HtmlHeaderFooter() With {
    .HtmlFragment = "
        <div style='border-top: 1px solid #ccc; padding: 8px; font-size: 10px;

How Do You Configure PDF Page Layout and Rendering Options?

IronPDF gives you full control over the page layout, margins, DPI, and CSS rendering behavior through the RenderingOptions property. This is where you configure paper size, print vs. screen CSS, and interactive form generation.

Key Rendering Options

using IronPdf;

var renderer = new ChromePdfRenderer();

// Set paper dimensions and orientation
renderer.RenderingOptions.PaperSize = IronPdf.Rendering.PdfPaperSize.Letter;
renderer.RenderingOptions.PaperOrientation = IronPdf.Rendering.PdfPaperOrientation.Portrait;

// Define margins (values in millimeters)
renderer.RenderingOptions.MarginTop = 25;
renderer.RenderingOptions.MarginBottom = 25;
renderer.RenderingOptions.MarginLeft = 19;
renderer.RenderingOptions.MarginRight = 19;

// Use print-specific CSS rules and set output DPI
renderer.RenderingOptions.CssMediaType = IronPdf.Rendering.PdfCssMediaType.Print;
renderer.RenderingOptions.DPI = 300;

// Preserve HTML form elements as interactive PDF form fields
renderer.RenderingOptions.CreatePdfFormsFromHtml = true;

var pdf = renderer.RenderHtmlAsPdf("<h1>Custom Layout Document</h1><p>Content with configured layout.</p>");
pdf.SaveAs("configured-output.pdf");
using IronPdf;

var renderer = new ChromePdfRenderer();

// Set paper dimensions and orientation
renderer.RenderingOptions.PaperSize = IronPdf.Rendering.PdfPaperSize.Letter;
renderer.RenderingOptions.PaperOrientation = IronPdf.Rendering.PdfPaperOrientation.Portrait;

// Define margins (values in millimeters)
renderer.RenderingOptions.MarginTop = 25;
renderer.RenderingOptions.MarginBottom = 25;
renderer.RenderingOptions.MarginLeft = 19;
renderer.RenderingOptions.MarginRight = 19;

// Use print-specific CSS rules and set output DPI
renderer.RenderingOptions.CssMediaType = IronPdf.Rendering.PdfCssMediaType.Print;
renderer.RenderingOptions.DPI = 300;

// Preserve HTML form elements as interactive PDF form fields
renderer.RenderingOptions.CreatePdfFormsFromHtml = true;

var pdf = renderer.RenderHtmlAsPdf("<h1>Custom Layout Document</h1><p>Content with configured layout.</p>");
pdf.SaveAs("configured-output.pdf");
Imports IronPdf

Dim renderer As New ChromePdfRenderer()

' Set paper dimensions and orientation
renderer.RenderingOptions.PaperSize = IronPdf.Rendering.PdfPaperSize.Letter
renderer.RenderingOptions.PaperOrientation = IronPdf.Rendering.PdfPaperOrientation.Portrait

' Define margins (values in millimeters)
renderer.RenderingOptions.MarginTop = 25
renderer.RenderingOptions.MarginBottom = 25
renderer.RenderingOptions.MarginLeft = 19
renderer.RenderingOptions.MarginRight = 19

' Use print-specific CSS rules and set output DPI
renderer.RenderingOptions.CssMediaType = IronPdf.Rendering.PdfCssMediaType.Print
renderer.RenderingOptions.DPI = 300

' Preserve HTML form elements as interactive PDF form fields
renderer.RenderingOptions.CreatePdfFormsFromHtml = True

Dim pdf = renderer.RenderHtmlAsPdf("<h1>Custom Layout Document</h1><p>Content with configured layout.</p>")

How Do You Generate PDFs in ASP.NET Core MVC?

In ASP.NET Core MVC, you return a PDF directly from a controller action using File(). The pattern is to render an internal URL or HTML string to a PdfDocument object, then return its binary data with the application/pdf MIME type.

Returning a PDF from a Controller Action

The following example renders an internal report URL and returns the result as a file download. The Microsoft ASP.NET Core MVC documentation covers the base Controller class and File() return type in detail:

using IronPdf;
using Microsoft.AspNetCore.Mvc;

public class ReportsController : Controller
{
    public IActionResult GeneratePdf()
    {
        var renderer = new ChromePdfRenderer();

        renderer.RenderingOptions.PaperSize = IronPdf.Rendering.PdfPaperSize.Letter;
        renderer.RenderingOptions.MarginTop = 20;
        renderer.RenderingOptions.MarginBottom = 20;

        // Add a text footer with page numbers
        renderer.RenderingOptions.TextFooter = new TextHeaderFooter()
        {
            CenterText = "Page {page} of {total-pages}",
            FontSize = 9
        };

        // Build the URL to the internal report page and render it
        string reportUrl = $"{Request.Scheme}://{Request.Host}/reports/quarterly";
        var pdf = renderer.RenderUrlAsPdf(reportUrl);

        return File(pdf.BinaryData, "application/pdf", "quarterly-report.pdf");
    }
}
using IronPdf;
using Microsoft.AspNetCore.Mvc;

public class ReportsController : Controller
{
    public IActionResult GeneratePdf()
    {
        var renderer = new ChromePdfRenderer();

        renderer.RenderingOptions.PaperSize = IronPdf.Rendering.PdfPaperSize.Letter;
        renderer.RenderingOptions.MarginTop = 20;
        renderer.RenderingOptions.MarginBottom = 20;

        // Add a text footer with page numbers
        renderer.RenderingOptions.TextFooter = new TextHeaderFooter()
        {
            CenterText = "Page {page} of {total-pages}",
            FontSize = 9
        };

        // Build the URL to the internal report page and render it
        string reportUrl = $"{Request.Scheme}://{Request.Host}/reports/quarterly";
        var pdf = renderer.RenderUrlAsPdf(reportUrl);

        return File(pdf.BinaryData, "application/pdf", "quarterly-report.pdf");
    }
}
