Answer 1

Use iText 7 and this code:

public void generatePDF(String htmlFile) {
    try {

        //HTML String
        String htmlString = htmlFile;
        //Setting destination 
        FileOutputStream fileOutputStream = new FileOutputStream(new File(dirPath + "/USER-16-PF-Report.pdf"));

        PdfWriter pdfWriter = new PdfWriter(fileOutputStream);
        ConverterProperties converterProperties = new ConverterProperties();
        PdfDocument pdfDocument = new PdfDocument(pdfWriter);

        //For setting the PAGE SIZE
        pdfDocument.setDefaultPageSize(new PageSize(PageSize.A3));

        Document document = HtmlConverter.convertToDocument(htmlFile, pdfDocument, converterProperties);
        document.close();
    } 
    catch (Exception e) {
         e.printStackTrace();
    }

}
