Compressing TIFF Image

Question

Hi guys,
Am trying to convert images on a folder to an TIFF format, It's working but the size of TIFF is too high. I have tried to compress the tiff using JAI encoder, still it's not working. Any body help me to reduce or compress the TIFF size on this please.
class imageFolder
     private static ImageEncoder enc = null;
     public boolean createTiffImage(String Foldername)
          try
               File dir = new File(Foldername);
               String[] children = dir.list();
               if (children == null)
                    System.out.println("No Images");
                    return false;
               else if (children.length == 0)
                    System.out.println("No Images");
                    return false;
               else
                    ImageWriter writer = null;
                    Iterator iter = ImageIO.getImageWritersByFormatName("tiff");
                    if (iter.hasNext())
                    writer = (ImageWriter)iter.next();
                    ImageOutputStream ios = ImageIO.createImageOutputStream(new File(Foldername+"ParentFile.tiff"));
                    writer.setOutput(ios);
                    FileInputStream ins = new FileInputStream(Foldername+children[0]);
                    BufferedImage img = ImageIO.read(ins);
                    ByteArrayOutputStream out = new ByteArrayOutputStream();
                    TIFFEncodeParam param = new TIFFEncodeParam();
                    param.setCompression(TIFFEncodeParam.COMPRESSION_DEFLATE);
                    ImageEncoder tiffEncoder = ImageCodec.createImageEncoder("TIFF",out, param);
                    tiffEncoder.encode(img);
                    System.out.println("File is created in the folder " + Foldername);
                    TIFFImageWriteParam tiffWriteParam = new TIFFImageWriteParam(Locale.US);
                    tiffWriteParam.setTilingMode(ImageWriteParam.MODE_EXPLICIT);
                    Graphics2D big = img.createGraphics();
          big.setFont(new Font("Dialog", Font.PLAIN, 10));
          big.setColor(Color.red);
               //big.drawString("", 4, 12);
          big.drawString("Sample Number", 4, 12);
                    writer.write(new IIOImage(img, null, null));
                    for (int i=1; i<=children.length; i++)
                         System.out.println(children.length);
                         ins = new FileInputStream(Foldername+children);
                         img = ImageIO.read(ins);
                         big = img.createGraphics();
               big.setFont(new Font("Dialog", Font.PLAIN, 10));
               big.setColor(Color.red);
                    big.drawString("", 4, 12);
               big.drawString("Sample Number", 4, 12);
                         writer.writeInsert(i, new IIOImage(img, null, null), null);
                    encodeAsTIFF(img,"ParentFile.tiff");
                    ios.flush();
                    writer.dispose();
                    ios.close();
                    return true;
          catch(Exception e)
               e.printStackTrace();
               return false;
     public static void main(String a[]) throws IOException
          imageFolder m1 = new imageFolder();
          String Foldername="e:/images/";
          System.out.println(m1.createTiffImage(Foldername));
     private static void encodeAsTIFF(BufferedImage bi, String outputFile) {
try {
outputFile = removeLastExt(outputFile)+".tiff";
OutputStream os = new FileOutputStream(outputFile);
TIFFEncodeParam param = new TIFFEncodeParam();
enc = ImageCodec.createImageEncoder("TIFF", os, param);
enc.encode(bi);
os.close();
} catch (IOException e) {
System.out.println("IOException at TIFF encoding..");
System.exit(1);
private static String removeLastExt(String name) {
int li = name.lastIndexOf(".");
return name.substring(0, li);

Hi,
This is the code I use to code compresses tiff images, it handles multi-page tiffs and could be of use.
I think the problem with your code is that the line tiffEncoder.encode(img); writes the output to the OutputStream associated with the ImageEncoder and doesn't modify the original RenderedImage.
public static byte[] compressTiff(byte[] data)
    try
        ByteArrayOutputStream bos = new ByteArrayOutputStream();
        ImageReader reader = (ImageReader)ImageIO.getImageReadersByFormatName("tiff").next();
        ImageInputStream imageInputStream =
            ImageIO.createImageInputStream(new ByteArrayInputStream(data));
        reader.setInput(imageInputStream);
        Iterator writers = ImageIO.getImageWritersByFormatName("tiff");
        ImageWriter writer = (ImageWriter)writers.next();
        int numPages = reader.getNumImages(true);
        List images = new ArrayList();
        for (int i = 0; i < numPages; i++ )
            images.add(reader.read(i));
        ImageOutputStream ios = ImageIO.createImageOutputStream(bos);
        writer.setOutput(ios);
        TIFFImageWriteParam param = new TIFFImageWriteParam(Locale.getDefault());
        param.setCompressionMode(TIFFImageWriteParam.MODE_EXPLICIT);
        param.setCompressionType("Deflate");
        BufferedImage firstIioImage = (BufferedImage)images.remove(0);
        writer.write(null, new IIOImage(firstIioImage, null, null), param);
        for (int i = 0; i < images.size(); i++)
            writer.writeInsert(i + 1, new IIOImage((BufferedImage)images.get(i), null, null), param);
        writer.dispose();
        ios.close();
        return bos.toByteArray();
    catch (IOException ex)
        throw new RuntimeException(ex);
}
