itextpdf 5.5.1 Issue with PDF content resolution w

i am working in HTML to PDF conversion using ItextPdf 5.5.1 and XMLWorker 5.5.1 in Java. i managed to convert PDF document having height as that of HTML contents but contents in PDF looking bigger and having unwanted spaces between lines. These spaces are not there in HTML document.

private static void createPdf() {

    try {
        // getting HTML file from the path
        InputStream is = new FileInputStream(new File("/Users/salman.nazir/Desktop/html/tq.txt"));
        Date now = new Date();

        File file = new File(("/Users/salman.nazir/Desktop"), "my_" + now.getTime() + ".pdf");

        ElementList el = parseToElementList(is, new XMLWorkerFontProvider("resources/fonts/"));

        // width of 204pt
        float width = 204;

        // height as 10000pt (which is much more than we'll ever need)
        float max = 10000;

        //column without a `writer`
        ColumnText ct = new ColumnText(null);

        ct.setSimpleColumn(new Rectangle(width, max));
        for (Element e : el) {


            // Add only HTML Body Element
            // Avoiding IllegalArgumentException ("Format not found.")

            if(!e.isContent()) {
                System.out.print("META DATA");
            }
            else {
                ct.addElement(e);
            }
        }
        ct.go(true);

        // Getting y posItion from simulation mode
        float y = ct.getYLine();
        Rectangle pagesize = new Rectangle(width, (max - y) + 25);
        // Document with predefined page size
        Document document = new Document(pagesize, 0, 0, 0, 0);
        // Getting PDF Writer
        PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream(file));
        document.open();
        // Column with a writer
        ct = new ColumnText(writer.getDirectContent());
        ct.setSimpleColumn(pagesize);
        for (Element e : el) {

            // Add only HTML Body Element
            // Avoiding IllegalArgumentException ("Format not found.")

            if(!e.isContent()) {
                System.out.print("META DATA");
            }
            else {
                ct.addElement(e);
            }
        }
        ct.go();
        // closing the document
        document.close();

        showPDFPath(file.getAbsolutePath());

    } catch (Exception e) {
        e.printStackTrace();

    }
}

is there any thing to set resolution anywhere in the code ? here is HTML code that is working fine in browser.
