IronPDF is a versatile PDF library designed to handle a wide range of PDF operations, including adding page numbers. IronPDF operates internally on a Chromium engine, allowing it to offer precise rendering of HTML content as PDFs. With its simple API, adding page numbers to your PDF is both efficient and straightforward.

The following code is an example of how to add page numbers using IronPDF in C#:

using IronPdf;
class Program
{
    static void Main(string[] args)
    {
        var html = "<h1>Hello World!</h1><p>This document was generated using IronPDF</p>";

        // Instantiate ChromePdfRenderer
        ChromePdfRenderer renderer = new ChromePdfRenderer()
        {
            // Set rendering options for page header
            RenderingOptions = {
                HtmlHeader = new HtmlHeaderFooter
                {
                    HtmlFragment = "<center><i>{page} of {total-pages}</i></center>" // Page number format
                },
            }
        };

        // Render given HTML as PDF
        PdfDocument pdf = renderer.RenderHtmlAsPdf(html);

        // Save the resulting PDF with page numbers
        pdf.SaveAs("pageNumbers.pdf");
    }
}

using IronPdf;
class Program
{
    static void Main(string[] args)
    {
        var html = "<h1>Hello World!</h1><p>This document was generated using IronPDF</p>";

        // Instantiate ChromePdfRenderer
        ChromePdfRenderer renderer = new ChromePdfRenderer()
        {
            // Set rendering options for page header
            RenderingOptions = {
                HtmlHeader = new HtmlHeaderFooter
                {
                    HtmlFragment = "<center><i>{page} of {total-pages}</i></center>" // Page number format
                },
            }
        };

        // Render given HTML as PDF
        PdfDocument pdf = renderer.RenderHtmlAsPdf(html);

        // Save the resulting PDF with page numbers
        pdf.SaveAs("pageNumbers.pdf");
    }
}

Output

This code demonstrates how to easily insert page numbers in the header of a PDF document. The HtmlHeaderFooter object is used to specify the header content, and placeholders like {page} and {total-pages} automatically populate with the page number and the total page count respectively.

With this approach, IronPDF simplifies the process of rendering HTML as PDFs while managing page number placement effortlessly.

PDFSharp is a comprehensive library for working with PDFs in C#. It provides tools for creating, modifying, and reading PDFs. Though it is not designed specifically for HTML-to-PDF conversion, it offers robust control over PDF documents, including the ability to add page numbers using custom page events. Whether you wish to add page numbers to just the first page, or second page, a range of pages, or just all of them.

Here’s an example of how to add page numbers using PDFSharp:

using PdfSharp.Pdf;
using PdfSharp.Pdf.IO;
using PdfSharp.Drawing;
internal class Program
{
    static void Main(string[] args)
    {
        // Create a new PDF document
        var doc = new PdfDocument();
        doc.Info.Title = "Page Numbers Example";

        // Add a new page to the document
        PdfPage page = doc.AddPage();

        // Create graphics object for drawing
        var gfx = XGraphics.FromPdfPage(page);
        var font = new XFont("Arial", 12);

        // Draw page number in the footer
        gfx.DrawString("Page " + doc.PageCount, font, XBrushes.Black, new XPoint(500, 770));

        // Save the PDF file
        doc.Save("PdfSharpOutput.pdf");
    }
}

using PdfSharp.Pdf;
using PdfSharp.Pdf.IO;
using PdfSharp.Drawing;
internal class Program
{
    static void Main(string[] args)
    {
        // Create a new PDF document
        var doc = new PdfDocument();
        doc.Info.Title = "Page Numbers Example";

        // Add a new page to the document
        PdfPage page = doc.AddPage();

        // Create graphics object for drawing
        var gfx = XGraphics.FromPdfPage(page);
        var font = new XFont("Arial", 12);

        // Draw page number in the footer
        gfx.DrawString("Page " + doc.PageCount, font, XBrushes.Black, new XPoint(500, 770));

        // Save the PDF file
        doc.Save("PdfSharpOutput.pdf");
    }
}
