Remove PDF Restrictions

The Java code below removes any PDF restrictions if they exist on the document .  The program accepts two arguments, the input and output file names, which can be the same if desired.  The program requires a couple pieces from the PDFBox subproject library, available at https://pdfbox.apache.org/download.cgi. 

This code will not open a PDF that requires a master password, but it's a simple addition to add that to the PDDocument.load().

import java.io.File;

import java.io.IOException;

import org.apache.pdfbox.pdmodel.PDDocument;

import org.apache.pdfbox.pdmodel.encryption.InvalidPasswordException;

public class pdfRemove {

  public static void main(String[] args) throws InvalidPasswordException, IOException {

    File file = new File(args[0]); 

PDDocument document = PDDocument.load(file);

    if (document.isEncrypted()) {
      document.setAllSecurityToBeRemoved(true);

}

    document.save(new File(args[1]));

document.close(); 

    }

  

}
