To convert TIFF images to PDF/JPEG in Java, just use the iText PDF (version 5.1.3) library to read Tiff files and create a PDF from it.

This code will convert all TIFF files to PDF/JPG. The most common issue you will get is "Byte array is not a valid JPEG-file." & "jpeg 2000 Old format"

public static void TiffToJpg(String tiff, String output)
            throws IOException, DocumentException {

        // PDF conversation starts here
        Document document = new Document();

        FileOutputStream fos = new FileOutputStream(output);
        PdfWriter writer = PdfWriter.getInstance(document, fos);
        writer.open();

        document.open();

        String fileName = tiff;
        Iterator readers = javax.imageio.ImageIO
                .getImageReadersBySuffix("tiff");
        if (readers.hasNext()) {
            File fi = new File(fileName);
            ImageInputStream iis = javax.imageio.ImageIO
                    .createImageInputStream(fi);
            TIFFDecodeParam param = null;
            ImageDecoder dec = ImageCodec.createImageDecoder("tiff", fi, param);
            int pageCount = dec.getNumPages();
            ImageReader _imageReader = (ImageReader) (readers.next());

            if (_imageReader != null) {
                _imageReader.setInput(iis, true);
                int count = 1;
                for (int i = 0; i < pageCount; i++) {
                    BufferedImage bufferedImage = _imageReader.read(i);

                    BufferedImage img2 = new BufferedImage(
                            bufferedImage.getWidth(),
                            bufferedImage.getHeight(),
                            BufferedImage.TYPE_INT_RGB);

                    // Set the RGB values for converted image (jpg)
                    for (int y = 0; y < bufferedImage.getHeight(); y++) {
                        for (int x = 0; x < bufferedImage.getWidth(); x++) {
                            img2.setRGB(x, y, bufferedImage.getRGB(x, y));
                        }
                    }

                    System.out.println("Page: " + (i + 1));
                    // Set the RGB values for converted image (jpg)

                   //To image
                      /*  String s = "C:/Users/TIFF/tiff"+i+".jpg";
                    ImageIO.write(img2, "jpg", new File(s));*/

                    //To pdf
                    ByteArrayOutputStream baos = new ByteArrayOutputStream();
                    ImageIO.write(img2, "jpg", baos);
                    baos.flush();
                    // Convert byteArrayoutputSteam to ByteArray
                    byte[] imageInByte = baos.toByteArray();
                    document.add(Image.getInstance(imageInByte));
                    baos.close();

                }
                document.close();
            }
        }
    }
