How to Convert HTML(Webpage) to PDF with C#/VB.NET


Because the wonderful reading effect of PDF documents, people would like to convert their electronic documents to PDF, especially articles and papers. Besides it, the other advantage of PDF document is that it can include lots of contents which can make our document be more appealed to readers, for example, comic images, audio, even video. In this post, I will introduce a method to convert HTML to PDF by using C# and VB.NET. It doesn’t means to convert a HTML file to PDF, but the contents in one webpage to a PDF document.


Sometimes, we want to introduce a website to others, such as own homepage or blog in PDF. Just with a hyperlink, people will have no interest with it, while, if we present the contents in this website, people may feel better. At that time, we need to convert this website to PDF.

Following, the method I will give is very simple because I use a .NET PDF component, Spire.PDF for .NET. Therefore, before starting with coding, I add its dll file as reference in my project. After everything is prepared, we can go to steps.


  1. Create a blank PDF document
  2. Add website address and load this address in PDF document. In this step, we need to send four parameters to LoadFromHTML method, url string, bool value to enable JavaScript or not, bool value to enable hyperlinks or not, bool value to auto detect page break.
  3. Save and launch file.

Main Coding (C#):

using System;
using Spire.Pdf;

namespace HTMLtoPDF
    class fromhtml
        static void Main(string[] args)
            //Create PDF
            PdfDocument doc = new PdfDocument();

            //Load Website
            String url =”;
            doc.LoadFromHTML(url, false, true, true);

            //Save PDF

            //Launch PDF


Imports System
Imports Spire.Pdf

Namespace HTMLtoPDF
       Friend Class fromhtml
              Shared Sub Main(ByVal args() As String)

                     ‘Create PDF Document
                     Dim doc As New PdfDocument()
                     Dim page As PdfPageBase = doc.Pages.Add()
                     ‘Load Website
                     Dim url As String =;
                     doc.LoadFromHTML(url, False, True, True)

                     ‘Save PDF

                     ‘Launch Pdf
              End Sub
       End Class
End Namespace

    You actually make it appear really easy with your presentation however I find this topic to be really
    one thing that I believe I’d by no means understand. It seems too complex and very broad for me. I am looking forward to your subsequent put up, I will try to get the hang of it!
