Split PDF File in Java

In this article, I will introduce two methods to split a PDF file in Java application:

1. Split a PDF to single page PDF files

2. Split a PDF to multiple PDF files by page range

The below examples use Free Spire.PDF for Java library.

Imported NameSpace:

import com.spire.pdf.PdfDocument;
import com.spire.pdf.PdfPageBase;
import com.spire.pdf.graphics.PdfMargins;

import java.awt.geom.Point2D;

Split a PDF to single page PDF files

//load the PDF file
PdfDocument doc = new PdfDocument();
doc.loadFromFile("sample.pdf");

//split every page of the PDF into a separate file
doc.split("Split/splitDocument-{0}.pdf", 0);
doc.close();

Split a PDF to multiple PDF by page range

//load the PDF file
PdfDocument doc = new PdfDocument();
doc.loadFromFile("sample.pdf");

//create a new PDF file
PdfDocument newDoc1 = new PdfDocument();
PdfPageBase page;

//add 2 pages to the new PDF, and draw the content of page 1-2 of the original PDF to the new added pages
for(int i = 0;i<2;i++)
{
    page = newDoc1.getPages().add(doc.getPages().get(i).getSize(), new PdfMargins(0));
    doc.getPages().get(i).createTemplate().draw(page, new Point2D.Float(0,0));
}

//save the result file
newDoc1.saveToFile("Split/Doc1.pdf");

//create a new PDF file
PdfDocument newDoc2 = new PdfDocument();

//add 3 pages to the new PDF, and draw the content of page 3-5 of the original PDF to the new added pages
for(int i = 2;i<5;i++)
{
    page = newDoc2.getPages().add(doc.getPages().get(i).getSize(), new PdfMargins(0));
    doc.getPages().get(i).createTemplate().draw(page, new Point2D.Float(0,0));
}

//save the result file
newDoc2.saveToFile("Split/Doc2.pdf");
