iText tutorial: Merge & Split PDF files using iText JAR

In previous article about Generating PDF files using iText JAR, Kiran Hegde had described a nice and basic way of generating PDF files in Java using iTest JAR. It is a great starter tutorial for those who wants to start working with iText. In one of the requirement, I had to merge two or more PDF files and generate a single PDF file out of it. I thought of implementing the functionality from scratch in iText, but then thought to google it and see if already someone have written code for what I was looking for. As expected, I got a nice implementation of java code that merges 2 or more PDF files using iText jar. I thought of dissecting the code in this post and give credit to original author of the post.

Merge PDF files in Java using iText JAR

So here we go. First let us see the code.

package net.viralpatel.itext.pdf;

import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;

import com.lowagie.text.Document;
import com.lowagie.text.pdf.BaseFont;
import com.lowagie.text.pdf.PdfContentByte;
import com.lowagie.text.pdf.PdfImportedPage;
import com.lowagie.text.pdf.PdfReader;
import com.lowagie.text.pdf.PdfWriter;

public class MergePDF {

 public static void main(String[] args) {
  try {
   List<InputStream> pdfs = new ArrayList<InputStream>();
   pdfs.add(new FileInputStream("c:\\1.pdf"));
   pdfs.add(new FileInputStream("c:\\2.pdf"));
   OutputStream output = new FileOutputStream("c:\\merge.pdf");
   MergePDF.concatPDFs(pdfs, output, true);
  } catch (Exception e) {
   e.printStackTrace();
  }
 }

 public static void concatPDFs(List<InputStream> streamOfPDFFiles,
   OutputStream outputStream, boolean paginate) {

  Document document = new Document();
  try {
   List<InputStream> pdfs = streamOfPDFFiles;
   List<PdfReader> readers = new ArrayList<PdfReader>();
   int totalPages = 0;
   Iterator<InputStream> iteratorPDFs = pdfs.iterator();

   // Create Readers for the pdfs.
   while (iteratorPDFs.hasNext()) {
    InputStream pdf = iteratorPDFs.next();
    PdfReader pdfReader = new PdfReader(pdf);
    readers.add(pdfReader);
    totalPages += pdfReader.getNumberOfPages();
   }
   // Create a writer for the outputstream
   PdfWriter writer = PdfWriter.getInstance(document, outputStream);

   document.open();
   BaseFont bf = BaseFont.createFont(BaseFont.HELVETICA,
     BaseFont.CP1252, BaseFont.NOT_EMBEDDED);
   PdfContentByte cb = writer.getDirectContent(); // Holds the PDF
   // data

   PdfImportedPage page;
   int currentPageNumber = 0;
   int pageOfCurrentReaderPDF = 0;
   Iterator<PdfReader> iteratorPDFReader = readers.iterator();

   // Loop through the PDF files and add to the output.
   while (iteratorPDFReader.hasNext()) {
    PdfReader pdfReader = iteratorPDFReader.next();

    // Create a new page in the target for each source page.
    while (pageOfCurrentReaderPDF < pdfReader.getNumberOfPages()) {
     document.newPage();
     pageOfCurrentReaderPDF++;
     currentPageNumber++;
     page = writer.getImportedPage(pdfReader,
       pageOfCurrentReaderPDF);
     cb.addTemplate(page, 0, 0);

     // Code for pagination.
     if (paginate) {
      cb.beginText();
      cb.setFontAndSize(bf, 9);
      cb.showTextAligned(PdfContentByte.ALIGN_CENTER, ""
        + currentPageNumber + " of " + totalPages, 520,
        5, 0);
      cb.endText();
     }
    }
    pageOfCurrentReaderPDF = 0;
   }
   outputStream.flush();
   document.close();
   outputStream.close();
  } catch (Exception e) {
   e.printStackTrace();
  } finally {
   if (document.isOpen())
    document.close();
   try {
    if (outputStream != null)
     outputStream.close();
   } catch (IOException ioe) {
    ioe.printStackTrace();
   }
  }
 }
}

If you see what the code does is pretty simple.

In main() method, we create a List of InputStream objects that points to all the input PDF files we need to merge
We call MergePDF.concatPDFs() static method passing list of input PDFs, OutputStream object for merged output PDF and a boolean flag that represents whether you need to include page numbers at the end of each page as command line arguments
In concatPDFs() method, first we convert List of InputStream objects to List of PdfReader objects in first while loop. And also we keep count of the total pages in all the input PDF files.
Next we create BaseFont object using BaseFont.createFont() method. This will be the font for writing page numbers
Next we create output objects to write our merged PDF file using Document class object and PdfWriter.getInstance() method
Finally we write all the input PDFs into merged output PDF iterating each PDF and then writing each page of it in two while loops
And then, close all the streams and clear all the buffers. Good boys do this ;-)

So now we know how to merge PDF files into one, let us see the way to split a PDF file or extract a part of PDF into another PDF.

Split PDF files in Java using iText JAR

Let us see the code.

/**
 * @author viralpatel.net
 * 
 * @param inputStream Input PDF file
 * @param outputStream Output PDF file
 * @param fromPage start page from input PDF file
 * @param toPage end page from input PDF file
 */
public static void splitPDF(InputStream inputStream,
  OutputStream outputStream, int fromPage, int toPage) {
 Document document = new Document();
 try {
  PdfReader inputPDF = new PdfReader(inputStream);

  int totalPages = inputPDF.getNumberOfPages();

  //make fromPage equals to toPage if it is greater
  if(fromPage > toPage ) {
   fromPage = toPage;
  }
  if(toPage > totalPages) {
   toPage = totalPages;
  }


  // Create a writer for the outputstream
  PdfWriter writer = PdfWriter.getInstance(document, outputStream);

  document.open();
  PdfContentByte cb = writer.getDirectContent(); // Holds the PDF data
  PdfImportedPage page;

  while(fromPage <= toPage) {
   document.newPage();
   page = writer.getImportedPage(inputPDF, fromPage);
   cb.addTemplate(page, 0, 0);
   fromPage++;
  }
  outputStream.flush();
  document.close();
  outputStream.close();
 } catch (Exception e) {
  e.printStackTrace();
 } finally {
  if (document.isOpen())
   document.close();
  try {
   if (outputStream != null)
    outputStream.close();
  } catch (IOException ioe) {
   ioe.printStackTrace();
  }
 }
}
Code language: Java (java)

In above code, we have created a method splitPDF () that can be used to extracts pages out of a PDF and write it into another PDF. The code is pretty much self explanatory and is similar to the one to merge PDF files. Thus, if you need to split an input.pdf (having 20 pages) into output1.pdf (1-12 pages of input.pdf) and output2.pdf (13-20 of input.pdf), you can call the above method as follow:

public static void main(String[] args) {
 try {
  MergePDF.splitPDF(new FileInputStream("C:\\input.pdf"), 
     new FileOutputStream("C:\\output1.pdf"), 1, 12);
  MergePDF.splitPDF(new FileInputStream("C:\\input.pdf"), 
     new FileOutputStream("C:\\output2.pdf"), 13, 20);
  
 } catch (Exception e) {
  e.printStackTrace();
 }
}

Hi ,
I want to split the pdf if my pdf exceeds the given size.
For Example,
If my pdf size is 12MB,I want to split the pdf in to 5MB parts.
So i need to split the pdf in to 3, 5MB,5MB,2MB respectively.
Pls let me know whether this is possible.

Regards,
Prem

@Prem, This example only splits the PDF on basis of page numbers. I will definitely try to write code for splitting pdf on basis of size and update you.

@Viral Patel, Thanks for the great comprehensive tutorial on merger two PDF's, it does work great, and always 2nd pdf concatenates at the end of the merge PDF, How to add PDF in between the merge PDF @say, given particular page number...Please give me directions, Thanks

I would like to paste my code here to split a PDF based on bookmarks using iText. All my bookmarks are on level1. I based my code sample on the example on this page, and that's why I would like to place my code here. I couldn't really find any example of splitting a PDF based on bookmarks with iText, so I thought it could help other people if I put my code on this page:

public static void splitPDFByBookmarks(String pdf, String outputFolder){
        try
        {
            PdfReader reader = new PdfReader(pdf);
            //List of bookmarks: each bookmark is a map with values for title, page, etc
            List<HashMap> bookmarks = SimpleBookmark.getBookmark(reader);
            for(int i=0; i<bookmarks.size(); i++){
                HashMap bm = bookmarks.get(i);
                HashMap nextBM = i==bookmarks.size()-1 ? null : bookmarks.get(i+1);
                //In my case I needed to split the title string
                String title = ((String)bm.get("Title")).split(" ")[2];
                
                log.debug("Titel: " + title);
                String startPage = ((String)bm.get("Page")).split(" ")[0];
                String startPageNextBM = nextBM==null ? "" + (reader.getNumberOfPages() + 1) : ((String)nextBM.get("Page")).split(" ")[0];
                log.debug("Page: " + startPage);
                log.debug("------------------");
                extractBookmarkToPDF(reader, Integer.valueOf(startPage), Integer.valueOf(startPageNextBM), title + ".pdf",outputFolder);
            }
        }
        catch (IOException e)
        {
            log.error(e.getMessage());
        }
    }
    
    private static void extractBookmarkToPDF(PdfReader reader, int pageFrom, int pageTo, String outputName, String outputFolder){
        Document document = new Document();
        OutputStream os = null;
        
        try{
            os = new FileOutputStream(outputFolder + outputName);

            // Create a writer for the outputstream
            PdfWriter writer = PdfWriter.getInstance(document, os);
            document.open();
            PdfContentByte cb = writer.getDirectContent(); // Holds the PDF data
            PdfImportedPage page;
    
            while(pageFrom < pageTo) {
                document.newPage();
                page = writer.getImportedPage(reader, pageFrom);
                cb.addTemplate(page, 0, 0);
                pageFrom++;
            }
            
            os.flush();
            document.close();
            os.close();
        }catch(Exception ex){
            log.error(ex.getMessage());
        }finally {
            if (document.isOpen())
                document.close();
            try {
                if (os != null)
                    os.close();
            } catch (IOException ioe) {
                log.error(ioe.getMessage());
            }
        }
    }

Hi Goblin_Queen

NOT getting "page" key in the bookmark hashmap.

I am getting the page key only for first and last bookmark & not able to see the page key in the map for other than first and last bookmark. Thats why i cant navigate the pages of bookmarks.
[code language="java"]
List bookmarks = SimpleBookmark.getBookmark(reader);
System.out.println(bookmarks.size()+" bookmarks =>"+bookmarks );
[/code]
The above two lines gives the following result...

Viral : If you already found the script for splitting pdfs by page size, it would be VERY handy
Thx in advance

Hi Viral,

By any chance is it possible to split the pages randomly? E.g. I have a PDF document of 20 pages and now I was a new PDF containing only 2nd, 5th, 11th and 16th page of the original document.

Thanks in advance.
Vishnu.
