You can use Spire.PDF library to add page numbers to the result PDF. First, install Spire.PDF via NuGet Package Manager. Second, refer to the following code to add page numbers. using Spire.Pdf; using Spire.Pdf.Graphics; using System; using Spire.Pdf.Widget; using System.Drawing; using Spire.Pdf.AutomaticFields; namespace AddPageNumbers { class Program { static void Main( string [] args) { PdfDocument doc = new PdfDocument(); doc.LoadFromFile(@ "C:\Users\Administrator\Desktop\sample.pdf" ); //set the margins PdfUnitConvertor unitCvtr = new PdfUnitConvertor(); PdfMargins margin = new PdfMargins(); margin.Top = unitCvtr.ConvertUnits(2.54f, PdfGraphicsUnit.Centimeter, PdfGraphicsUnit.Point); margin.Bottom = margin.Top; margin.Left = unitCvtr.ConvertUnits(3.17f, PdfGraphicsUnit.Centimeter, PdfGraphicsUnit.Point); margin.Right = margin.Left; //draw page number DrawPageNumber(doc.Pages, margin); //save the file doc.SaveToFile( "AddPageNumbers.pdf" , FileFormat.PDF); } private static void DrawPageNumber(PdfPageCollection collection, PdfMargins margin) { foreach (PdfPageBase page in collection) { PdfBrush brush = PdfBrushes.Black; PdfTrueTypeFont font = new PdfTrueTypeFont( new Font( "Arial" , 10f, FontStyle.Bold), true ); PdfStringFormat format = new PdfStringFormat(PdfTextAlignment.Left); int x = Convert.ToInt32(page.Canvas.ClientSize.Width / 2); int y = Convert.ToInt32(page.Canvas.ClientSize.Height-margin.Bottom); Rectangle bounds = new Rectangle(x, y, 50, 20); PdfPageNumberField field = new PdfPageNumberField(); field.Font = font; field.Brush = brush; field.StringFormat = format; field.Bounds = bounds; field.Draw(page.Canvas); } } } } For more information, visit this link: https://www.e-iceblue.com/Tutorials/Spire.PDF/Spire.PDF-Program-Guide/Page-Setting/How-to-Add-Page-Numbers-to-Existing-PDF-Document-in-C.html
