How to add blank pages to an existing PDF in java?

I have a normal PDF file, I want to insert blank pages at the end of this PDF using iText, without changing the existing PDF contents.

Please try this short code snippet:

PdfDocument pdfDoc = new PdfDocument(new PdfReader(src), new PdfWriter(dest));
int index = pdfDoc.getNumberOfPages();
PageSize ps = new PageSize(pdfDoc.getFirstPage().getPageSize());
pdfDoc.addNewPage(index + 1, ps);
pdfDoc.close();

If src refers to a document with 10 pages, the code above will add an extra blank 11th page, using the same page size as the first page. You can specify any index and ps values. If you don’t need these settings, iText 7 provides a simple method:

pdfDoc.addNewPage();
