        {
            // read parameters from the webpage
            string url = TxtUrl.Text;

            string pdf_page_size = DdlPageSize.SelectedValue;
            PdfPageSize pageSize = (PdfPageSize)Enum.Parse(typeof(PdfPageSize), 
                pdf_page_size, true);

            string pdf_orientation = DdlPageOrientation.SelectedValue;
            PdfPageOrientation pdfOrientation =

            int webPageWidth = 1024;
            try
            {
                webPageWidth = Convert.ToInt32(TxtWidth.Text);
            }
            catch { }

            int webPageHeight = 0;
            try
            {
                webPageHeight = Convert.ToInt32(TxtHeight.Text);
            }
            catch { }

            // instantiate a html to pdf converter object
            HtmlToPdf converter = new HtmlToPdf();

            // set converter options
            converter.Options.PdfPageSize = pageSize;
            converter.Options.PdfPageOrientation = pdfOrientation;
            converter.Options.WebPageWidth = webPageWidth;
            converter.Options.WebPageHeight = webPageHeight;

            // create a new pdf document converting an url
            PdfDocument doc = converter.ConvertUrl(url);

            // save pdf document
            doc.Save(Response, false, "Sample.pdf");

            // close pdf document
            doc.Close();
        }
    }
}

You can add the image from the URL into a PDF using the DocumentEditor. Here is the documentation and code that highlights this.

addImage = () => { // Load file
        //Allows the user to input an image of their choosing for the specific file types allowed at the cursor location 
        var input = document.createElement('input'); 
        input.type = 'file'; 
        input.style.display = 'none'; 
        input.accept = '.png, .docx, .doc, .jpg, .pdf'; 
        input.onchange = function (e) { 
            var files = input.files; 
            if (!files || !files.length) 
                return; 
            file = files[0]; 
            var url = URL.createObjectURL(file); 
            editor.engine.images.insertImage(url); 
        }; 
        input.click(); 
    }

exportAsPdf = () => { 
        //exports the current document for saving 
        var promise = editor.document.toFile("untitled", lt.Document.Writer.DocumentFormat.pdf); 
        var err = null; 
        promise.then(function (name: string) { }); 
        promise.catch(function (err: string) { 
            alert("There was an issue exporting the document. " + err); 
        }); 
    }

Add add these 2 dll in solution.

Itextsharp.dll
itextsharp.pdfa.dll

add namespaces  ----

using iTextSharp.text;
using iTextSharp.text.pdf;
using iTextSharp.text.html;
using iTextSharp.text.html.simpleparser;

protected void btnCreatePDF_Click(object sender, EventArgs e)
{
    Document doc = new Document(PageSize.A4, 10f, 10f, 100f, 0f);
    string pdfFilePath = Server.MapPath(".") + "/PDFFiles";
    PdfWriter writer = PdfAWriter.GetInstance(doc, new FileStream(pdfFilePath + "/Default.pdf", FileMode.Create));
    doc.Open();
    try
    {
        Paragraph paragraph = new Paragraph("Getting Started ITextSharp.");
        string imageURL = Server.MapPath(".") + "/image2.jpg";
        iTextSharp.text.Image jpg = iTextSharp.text.Image.GetInstance(imageURL);
        //Resize image depend upon your need
        jpg.ScaleToFit(140f, 120f);
        //Give space before image
        jpg.SpacingBefore = 10f;
        //Give some space after the image
        jpg.SpacingAfter = 1f;
        jpg.Alignment = Element.ALIGN_LEFT;
        doc.Add(paragraph);
        doc.Add(jpg);
    }
    catch (Exception ex)
    { }
    finally
    {
        doc.Close();
    }
}
