PDF is a stable file format, and it is difficult for us to duplicate a PDF page by simply copying and pasting. This article will introduce how I duplicate a page within a PDF document using a free Java library (Free Spire.PDF for Java).
Import jar dependency (2 Methods)
● Download the free library and unzip it. Then add the Spire.Pdf.jar file to your project as dependency.
● Directly add the jar dependency to maven project by adding the following configurations to the pom.xml.

public class DuplicatePage {
public static void main(String[] args) {
//Load a sample PDF document
PdfDocument pdf = new PdfDocument("C:\\Users\\Administrator\\Desktop\\The Scarlet Letter.pdf");
//Get the first page
PdfPageBase page = pdf.getPages().get(0);
//Get the page size
Dimension2D size = page.getActualSize();
//Create a template based on the page
PdfTemplate template = page.createTemplate();
for (int i = 0; i < 5; i++) {
//Add a new page to the document
page = pdf.getPages().add(size, new PdfMargins(0));
//Draw template on the new page
page.getCanvas().drawTemplate(template, new Point2D.Float(0, 0));
}
//Save the file
pdf.saveToFile("output/DuplicatePage.pdf");
}
}
