Splitting a large Pdf file with PDFBox gets large result files

Question

I am processing some large pdf files, (up to 100MB and about 2000 pages), with pdfbox. Some of the pages contain a QR code, I want to split those files into smaller ones wit

Thx! Tilman you are right, the PDFSplit command generates smaller files. I checked the PDFSplit code out and found that it removes the page links to avoid not needed resources.

Code extracted from Splitter.class :

private void processAnnotations(PDPage imported) throws IOException
    {
        List annotations = imported.getAnnotations();
        for (PDAnnotation annotation : annotations)
        {
            if (annotation instanceof PDAnnotationLink)
            {
                PDAnnotationLink link = (PDAnnotationLink)annotation;   
                PDDestination destination = link.getDestination();
                if (destination == null && link.getAction() != null)
                {
                    PDAction action = link.getAction();
                    if (action instanceof PDActionGoTo)
                    {
                        destination = ((PDActionGoTo)action).getDestination();
                    }
                }
                if (destination instanceof PDPageDestination)
                {
                    // TODO preserve links to pages within the splitted result  
                    ((PDPageDestination) destination).setPage(null);
                }
            }
            else
            {
                // TODO preserve links to pages within the splitted result  
                annotation.setPage(null);
            }
        }
    }

So eventually my code looks like this:

PDDocument documentoPdf = 
        PDDocument.loadNonSeq(new File("docs_compuestos/50.pdf"), new RandomAccessFile(new File("./tmp/t"), "rw"));

        int numPages = documentoPdf.getNumberOfPages();
        List pages = documentoPdf.getDocumentCatalog().getAllPages();


        int previusQR = 0;
        for(int i =0; i

Thank you very much!!
