Add Headers/Footers on Specific Pages

IronPDF has the ability to add headers and footers to existing PDF files.

We can also use methods of IronPDF to add customized Headers and Footers to old or new PDF documents. To do so, we wait until after the PDF is rendered using the following methods:

Below is an example of how you can add headers and footers to a PDF using the IronPDF library in C#:

using IronPdf;

class Program
{
    static void Main()
    {
        // Load an existing PDF document
        var pdfDocument = PdfDocument.FromFile("existing-document.pdf");

        // Create a text header
        var textHeader = new TextHeaderFooter()
        {
            CenterText = "My Company",
            DrawDividerLine = true // Draw a line beneath the header
        };

        // Add the text header to the PDF
        pdfDocument.AddHeaders(textHeader);

        // Create a text footer
        var textFooter = new TextHeaderFooter()
        {
            RightText = "Page {page} of {total-pages}", // Adds page number to the footer
            DrawDividerLine = true
        };

        // Add the text footer to the PDF
        pdfDocument.AddFooters(textFooter);

        // Save the PDF with new headers and footers
        pdfDocument.SaveAs("document-with-headers-and-footers.pdf");
    }
}

using IronPdf;

class Program
{
    static void Main()
    {
        // Load an existing PDF document
        var pdfDocument = PdfDocument.FromFile("existing-document.pdf");

        // Create a text header
        var textHeader = new TextHeaderFooter()
        {
            CenterText = "My Company",
            DrawDividerLine = true // Draw a line beneath the header
        };

        // Add the text header to the PDF
        pdfDocument.AddHeaders(textHeader);

        // Create a text footer
        var textFooter = new TextHeaderFooter()
        {
            RightText = "Page {page} of {total-pages}", // Adds page number to the footer
            DrawDividerLine = true
        };

        // Add the text footer to the PDF
        pdfDocument.AddFooters(textFooter);

        // Save the PDF with new headers and footers
        pdfDocument.SaveAs("document-with-headers-and-footers.pdf");
    }
}

Explanation:

Loading the PDF: An existing PDF document is loaded from a file using PdfDocument.FromFile().
Creating Headers and Footers:
- TextHeaderFooter(): This object is instantiated to define the content and style of text headers and footers.
- For the header, CenterText is set to display the company name, with an optional divider line.
- For the footer, RightText is set to display the current page number and total pages.
Adding Headers and Footers: The AddHeaders() and AddFooters() methods are used to apply headers and footers to the PDF document.
Saving the PDF: The modified document is saved with a new name.
