How to Duplicate Pages in a PDF in Java (Tutorial)

Sometimes you might want to duplicate pages in a PDF. For example, when filling in multiple copies of a form. Our Java PDF toolkit, JPedal, makes this an easy task.

In this post, I will show you the three simple steps of duplicating pages using JPedal.

1. Download JPedal

You can download a JPedal trial jar here.

2. Add to your project

For this example, I am going to use Maven. If you want to use another build system, check out the setup page on our support site.

Install the downloaded jar to your local Maven repository:

mvn install:install-file -Dfile= -DgroupId=com.idrsolutions -Dpackaging=jar -DartifactId=jpedal -Dversion=1.0

Add the following to your pom.xml file:

<dependencies>
    <dependency>
        <groupId>com.idrsolutions</groupId>
        <artifactId>jpedal</artifactId>
        <version>1.0</version>
    </dependency>
</dependencies>

3. Add to your code

Create an instance of PDF Manipulator and call the copy page method.

final PdfManipulator pdf = new PdfManipulator();
pdf.loadDocument(new File("inputFile.pdf"));
pdf.copyPage(1, 2);
pdf.apply();
pdf.writeDocument(new File("outputFile.pdf"));
pdf.closeDocument();
pdf.reset();
