Adding Page Numbers using IronPDF

IronPDF offers an easy way to add page numbers to PDFs. The following code demonstrates how to do this:

using IronPdf;
class Program
{
    static void Main(string[] args)
    {
        var html = "<h1>Hello World!</h1><p>This document was generated using IronPDF</p>";
        ChromePdfRenderer renderer = new ChromePdfRenderer()
        {
            RenderingOptions = {
                HtmlHeader = new HtmlHeaderFooter
                {
                    HtmlFragment = "<center><i>{page} of {total-pages}</i></center>"
                },
            }
        };
        PdfDocument pdf = renderer.RenderHtmlAsPdf(html);
        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>";
        ChromePdfRenderer renderer = new ChromePdfRenderer()
        {
            RenderingOptions = {
                HtmlHeader = new HtmlHeaderFooter
                {
                    HtmlFragment = "<center><i>{page} of {total-pages}</i></center>"
                },
            }
        };
        PdfDocument pdf = renderer.RenderHtmlAsPdf(html);
        pdf.SaveAs("pageNumbers.pdf");
    }
}

Imports IronPdf
Friend Class Program
	Shared Sub Main(ByVal args() As String)
		Dim html = "<h1>Hello World!</h1><p>This document was generated using IronPDF</p>"
		Dim renderer As New ChromePdfRenderer() With {
			.RenderingOptions = {
				HtmlHeader = New HtmlHeaderFooter With {.HtmlFragment = "<center><i>{page} of {total-pages}</i></center>"}
			}
		}
		Dim pdf As PdfDocument = renderer.RenderHtmlAsPdf(html)
		pdf.SaveAs("pageNumbers.pdf")
	End Sub
End Class

Output

In this code, we create an HTML header for the PDF document, where {page} and {total-pages} represent dynamic placeholders for the current page number and total pages. The RenderHtmlAsPdf method converts the HTML into a PDF. With this feature, you can choose to include a single page or however many of the next pages within the PDF.

How to Add Page Numbers using QuestPDF

In QuestPDF, adding page numbers can be done in a similar fashion. Below is the code to add page numbers using QuestPDF:

using QuestPDF.Fluent;
using QuestPDF.Infrastructure;
using QuestPDF;
class Program
{
    static void Main(string[] args)
    {
        QuestPDF.Settings.License = LicenseType.Community;
        var document = Document.Create(container =>
        {
            container.Page(page =>
            {
                page.Content().Text("Hello, QuestPDF!");
                page.Header().AlignCenter().Text(text =>
                {
                    text.Span("Page ");
                    text.CurrentPageNumber();
                    text.Span(" of ");
                    text.TotalPages();
                });
            });
        });
        document.GeneratePdf("QuestPdfOutput.pdf");
    }
}

using QuestPDF.Fluent;
using QuestPDF.Infrastructure;
using QuestPDF;
class Program
{
    static void Main(string[] args)
    {
        QuestPDF.Settings.License = LicenseType.Community;
        var document = Document.Create(container =>
        {
            container.Page(page =>
            {
                page.Content().Text("Hello, QuestPDF!");
                page.Header().AlignCenter().Text(text =>
                {
                    text.Span("Page ");
                    text.CurrentPageNumber();
                    text.Span(" of ");
                    text.TotalPages();
                });
            });
        });
        document.GeneratePdf("QuestPdfOutput.pdf");
    }
}

Imports QuestPDF.Fluent
Imports QuestPDF.Infrastructure
Imports QuestPDF
Friend Class Program
	Shared Sub Main(ByVal args() As String)
		QuestPDF.Settings.License = LicenseType.Community
		Dim document = Document.Create(Sub(container)
			container.Page(Sub(page)
				page.Content().Text("Hello, QuestPDF!")
				page.Header().AlignCenter().Text(Sub(text)
					text.Span("Page ")
					text.CurrentPageNumber()
					text.Span(" of ")
					text.TotalPages()
				End Sub)
			End Sub)
		End Sub)
		document.GeneratePdf("QuestPdfOutput.pdf")
	End Sub
End Class

This QuestPDF code defines a simple document with a page number in the header. The CurrentPageNumber() and TotalPages() methods are used to dynamically generate the page number relative to each page.

Conclusion
