Step 1 Install IronPDF

Download and install the IronPDF from the IronPDF website, or you can download and install using NuGet Package Manager in Visual Studio with the following command:

Install-Package IronPdf

Step 2 Import IronPdf and Create an HTML String

First import the IronPdf package and then create an HTML string to be converted to PDF with page numbers.

using IronPdf;

var html = @"
    <p> Hello Iron</p>
    <p> This is 1st Page </p>
    <div style = 'page-break-after: always;' ></div>
    <p> This is 2nd Page</p>
    <div style = 'page-break-after: always;' ></div>
    <p> This is 3rd Page</p>";
using IronPdf;

    <p> This is 1st Page </p>
    <div style = 'page-break-after: always;' ></div>
    <p> This is 2nd Page</p>
    <div style = 'page-break-after: always;' ></div>

Private html = "

    <p> This is 1st Page </p>
    <div style = 'page-break-after: always;' ></div>
    <p> This is 2nd Page</p>
    <div style = 'page-break-after: always;' ></div>
    <p> This is 3rd Page</p>"
VB   C#

Step 3 Instantiate ChromePdfRenderOptions and Customize Page Number Format

In the following code example, first we initialize a PDF renderer (ChromePdfRenderer) with specific HTML footer settings. It defines the content, styling, and layout of the footer that will be added to each page of the PDF when it is generated using HTML Header Footer class.

// Instantiate Renderer
var renderer = new ChromePdfRenderer
{
    RenderingOptions =
    {
        HtmlFooter = new HtmlHeaderFooter()
        {

            MaxHeight = 15, // millimeters
            HtmlFragment = "<center><i>{page} of {total-pages}<i></center>",
            DrawDividerLine = true
        }
    }
};
// Instantiate Renderer
var renderer = new ChromePdfRenderer
{
    RenderingOptions =
    {
        HtmlFooter = new HtmlHeaderFooter()
        {

            MaxHeight = 15, // millimeters
            HtmlFragment = "<center><i>{page} of {total-pages}<i></center>",
            DrawDividerLine = true
        }
    }
};
' Instantiate Renderer
Dim renderer = New ChromePdfRenderer With {
	.RenderingOptions = {
		HtmlFooter = New HtmlHeaderFooter() With {
			.MaxHeight = 15,
			.HtmlFragment = "<center><i>{page} of {total-pages}<i></center>",
			.DrawDividerLine = True
		}
	}
}
VB   C#

Step 4 Render HTML as PDF Document

Once you've configured your page numbering preferences, call the RenderHtmlAsPdf method to convert it to PDF. IronPDF will apply the page numbers to each page of the PDF.

var pdf = renderer.RenderHtmlAsPdf(html);
var pdf = renderer.RenderHtmlAsPdf(html);
Dim pdf = renderer.RenderHtmlAsPdf(html)
VB   C#

Step 5 Save the PDF

After adding the page numbers, save the PDF document with the page numbers included.

pdf.SaveAs("pageNumber.pdf");
pdf.SaveAs("pageNumber.pdf");
pdf.SaveAs("pageNumber.pdf")
VB   C#

Here is the output:
