PDFBox Load Existing Document

This section describes how to load PDF document that already exists in our system. By loading the existing document we can perform many operations on it like adding text, removing text, adding an image, removing page etc.

Follow the steps below to load the existing PDF document -

Load Existing 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); 

Perform Operations

After loading the existing PDF document, we can perform the operations on it like adding text, removing text, adding an image, removing page etc.

Save Document

After adding 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;
import org.apache.pdfbox.pdmodel.PDPage;

public class Main {

	public static void main(String[] args)throws IOException {
			
	//Loading an existing document 
	      File file = new File("/eclipse-workspace/blanck.pdf"); 
	      PDDocument doc = PDDocument.load(file); 
	
	      System.out.println("PDF loaded"); 
	
	//Adding a blank page to the document 
	doc.addPage(new PDPage());  

	//Saving the document 
	doc.save("/eclipse-workspace/blanck.pdf");

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