I want to change the height of multi page TIFF image so I am using below code snippet to scale it. But It returns just first page from the tiff file , I guess it converts it to JPEG image. How to retain all pages of the file??

It has nothing to do with JPEGs. Here's code that shows how to read multi-image TIFFs: http://www.pagu.at/blog/multi-page-tiff-handling-with-imageio. Just ignore everything to do with PDFs.

Thank you Ulf Dittmer, I tried from the sample example but still getting single first page that too with OutOfMemory exception. Please find updated code below.

How big are the images? How much memory does the JVM have allocated?

Now I tried with ImageWriter
Below is the updated code which reads array of bytes,processes the image(scaling) and returns the array of bytes.I have not yet included scaling code. but now I don't get any image and no exception as well.

I don't quite follow that code. Please post a compilable version that reads a particular multi-page TIFF from the disk (say, "example.tiff"). If you do that I promise to look into it; this interests me.
