I want to convert into image. I am using code 

private static void StartBrowser(string source)
{
    var th = new Thread(() =>
    {
        var webBrowser = new WebBrowser();
        webBrowser.ScrollBarsEnabled = false;
        webBrowser.DocumentCompleted += webBrowser_DocumentCompleted;
        webBrowser.DocumentText = source;
        Application.Run();
    });
    th.SetApartmentState(ApartmentState.STA);
    th.Start();
}

static void webBrowser_DocumentCompleted(
    object sender,
    WebBrowserDocumentCompletedEventArgs e)
{
    var webBrowser = (WebBrowser)sender;
    using (Bitmap bitmap =
        new Bitmap(webBrowser.Width, webBrowser.Height))
    {
        webBrowser.DrawToBitmap(
            bitmap,
            new System.Drawing
                .Rectangle(0, 0, bitmap.Width, bitmap.Height));
        bitmap.Save(@"c:\\filename.jpg",
            System.Drawing.Imaging.ImageFormat.Jpeg);
    }
}
