@DolluM39Hi just simple create function for do it. below is sample code.

1. Download the pdfbox jar and import on Pega.

2. Create function and using method from pdf box

import java.io.File; 
import java.io.IOException; 

import java.util.List; 
import java.util.Iterator;  

public class SplittingPDF { 
   public static void main(String[] args) throws IOException { 
      
      //Loading an existing PDF document 
      File file = new File("C:/pdfBox/splitpdf_IP.pdf"); 
      PDDocument doc = PDDocument.load(file); 

      //Instantiating Splitter class 
      Splitter splitter = new Splitter(); 
      
      //splitting the pages of a PDF document 
      List<PDDocument> Pages = splitter.split(doc); 

      //Creating an iterator 
      Iterator<PDDocument> iterator = Pages.listIterator();         

      //Saving each page as an individual document 
      int i = 1; 
      
      while(iterator.hasNext()){ 
         PDDocument pd = iterator.next(); 
         pd.save("C:/pdfBox/splitOP"+ i++ +".pdf");             
      } 
      System.out.println("PDF splitted");     
   } 
}
