Вы можете Yse evopdf для этого. Пример кода: http://www.evopdf.com/demo/default.aspx:

protected void convertToPdfButton_Click(object sender, EventArgs e) 
    { 
    // Create a HTML to PDF converter object with default settings 
    HtmlToPdfConverter htmlToPdfConverter = new HtmlToPdfConverter(); 

    // Set license key received after purchase to use the converter in licensed mode 
    // Leave it not set to use the converter in demo mode 
    htmlToPdfConverter.LicenseKey = "4W9+bn19bn5ue2B+bn1/YH98YHd3d3c="; 

    // Set HTML Viewer width in pixels which is the equivalent in converter of the browser window width 
    htmlToPdfConverter.HtmlViewerWidth = int.Parse(htmlViewerWidthTextBox.Text); 

    // Set HTML viewer height in pixels to convert the top part of a HTML page 
    // Leave it not set to convert the entire HTML 
    if (htmlViewerHeightTextBox.Text.Length > 0) 
     htmlToPdfConverter.HtmlViewerHeight = int.Parse(htmlViewerHeightTextBox.Text); 

    // Set PDF page size which can be a predefined size like A4 or a custom size in points 
    // Leave it not set to have a default A4 PDF page 
    htmlToPdfConverter.PdfDocumentOptions.PdfPageSize = SelectedPdfPageSize(); 

    // Set PDF page orientation to Portrait or Landscape 
    // Leave it not set to have a default Portrait orientation for PDF page 
    htmlToPdfConverter.PdfDocumentOptions.PdfPageOrientation = SelectedPdfPageOrientation(); 

    // Set the maximum time in seconds to wait for HTML page to be loaded 
    // Leave it not set for a default 60 seconds maximum wait time 
    htmlToPdfConverter.NavigationTimeout = int.Parse(navigationTimeoutTextBox.Text); 

    // Set an adddional delay in seconds to wait for JavaScript or AJAX calls after page load completed 
    // Set this property to 0 if you don't need to wait for such asynchcronous operations to finish 
    if (conversionDelayTextBox.Text.Length > 0) 
     htmlToPdfConverter.ConversionDelay = int.Parse(conversionDelayTextBox.Text); 

    // The buffer to receive the generated PDF document 
    byte[] outPdfBuffer = null; 

    if (convertUrlRadioButton.Checked) 
    { 
     string url = urlTextBox.Text; 

     // Convert the HTML page given by an URL to a PDF document in a memory buffer 
     outPdfBuffer = htmlToPdfConverter.ConvertUrl(url); 
    } 
    else 
    { 
     string htmlString = htmlStringTextBox.Text; 
     string baseUrl = baseUrlTextBox.Text; 

     // Convert a HTML string with a base URL to a PDF document in a memory buffer 
     outPdfBuffer = htmlToPdfConverter.ConvertHtml(htmlString, baseUrl); 
    } 

    // Send the PDF as response to browser 

    // Set response content type 
    Response.AddHeader("Content-Type", "application/pdf"); 

    // Instruct the browser to open the PDF file as an attachment or inline 
    Response.AddHeader("Content-Disposition", String.Format("{0}; filename=Getting_Started.pdf; size={1}", 
     openInlineCheckBox.Checked ? "inline" : "attachment", outPdfBuffer.Length.ToString())); 

    // Write the PDF document buffer to HTTP response 
    Response.BinaryWrite(outPdfBuffer); 

    // End the HTTP response and stop the current page processing 
    Response.End(); 
}

Это не работает с asp.net 5 –

OK. Поэтому вы можете опубликовать причину, по которой ваш пользователь хочет конвертировать HTML в PDF. Используя evopdf, вы можете создать обработчик ASHX, который обработчик преобразует HTML-страницу (или строку HTML) в PDF и записывает в ответ. – feeeper
