PDFBox Removing Pages

We can remove pages from existing PDF document. removePage() method of the PDDocument class is used to remove the page from the document.

Follow the steps below to remove page from the existing PDF document-

Load PDF Document

We can load the existing PDF document by using the static load() method. This method accepts a file object as a parameter. We can also invoke it using the class name PDDocument of the PDFBox.

File file = new File("Path of Document"); 
PDDocument doc = PDDocument.load(file); 

List the Number of Pages

We need to list the number of pages that exist in the PDF document by using the getNumberOfPages() method as shown below.

intnoOfPages= doc.getNumberOfPages();	
System.out.print(noOfPages);

Remove Page

The removePage() method of the PDDocument class is used to remove a page from the document. In this method, we need to pass the index of the page as a parameter which we want to delete from the PDF document. The indexing of the page starts from zero which means, if we want to delete the 4th page from the PDF document then its index is 3.

Save Document

After removing the required document, we have to save it to our desired location. save() method is used to save the document. The save() method accepts a string value and passes a path of the document as a parameter.

Close Document

After completing the task, we need to close the PDDocument class object by using the close() method.

Example-

import java.io.File; 
import java.io.IOException;
import org.apache.pdfbox.pdmodel.PDDocument; 

public class RemovePage {	
	public static void main(String[] args)throws IOException {
		
		//Loading an existing document
	      File file = new File("/eclipse-workspace/blank.pdf");
	      PDDocument doc = PDDocument.load(file);
	
	//Listing the number of existing pages
	intnoOfPages= doc.getNumberOfPages();
	
	      System.out.print(noOfPages);
	
	//Removing the pages
	doc.removePage(1);
	
	      System.out.println("Page removed successfully.");

	//Saving the document
	doc.save(new File("/eclipse-workspace/blank.pdf"));

	//Closing the document
	doc.close();
	}
}

Output:

After successful execution of above program, we can see the following message.
