It seems that this question has been asked in many different forums. I googled and find the most proper one for you, in which no external PDF creator or PDF reader SDK is required. Hope it can help you a little.

" Have a look at chapter 6 of iText in Action, 2nd edition, especially at subsection 6.4.1: Concatenating and splitting PDF documents.
Listing 6.22, ConcatenateStamp.java, shows you how you should create a PDF from copies of pages (in your case: all pages) of multiple other PDFs; the sample additionally adds a new "Page X of Y" footer; this demonstrates how you can add content at given positions on the pages while merging the source files.

Hi Rahul,
Maybe it cannot be implemented directly, here is a kind of method to help draw the footer in existing pdf file. Of course, it need to use another component but not iTextSharp, it's Spire.PDF. Try the code below,
private static void DrawPageNumber(PdfPageCollection section, PdfMargins margin, int startNumber, int pageCount)
{
foreach (PdfPageBase page in section)
{
page.Canvas.SetTransparency(0.5f);
PdfBrush brush = PdfBrushes.Black;
PdfPen pen = new PdfPen(brush, 0.75f);
PdfTrueTypeFont font = new PdfTrueTypeFont(new Font("Arial", 10f, FontStyle.Bold), true);
PdfStringFormat format = new PdfStringFormat(PdfTextAlignment.Right);
format.MeasureTrailingSpaces = true;
float space = font.Height * 0.75f;
float x = margin.Left;
float width = page.Canvas.ClientSize.Width - margin.Left - margin.Right;
float y = page.Canvas.ClientSize.Height - margin.Bottom + space;
page.Canvas.DrawLine(pen, x, y, x + width, y);
y = y + 1;
String numberLabel
= String.Format("{0} of {1}", startNumber++, pageCount);
page.Canvas.DrawString(numberLabel, font, brush, x + width, y, format);
page.Canvas.SetTransparency(1);
}
}
