Using the above code to convert from jpeg to tiff.
I want to compress the image so using compression types from

Is there any other compression type or way which can give me more smaller or same size as that of original image?

Might be relevant. I've just noticed that what one creates the
then FileImageOutputStreamSpi creates, which in turn does new RandomAccessFile(f, "rw") and that does not overwrite / truncate the output file, but re-uses it. That means TIFFImageWriter writes to it up to necessary position, but the trailing "junk" stays there. Which means that if you write in your test scenario to the same output file, and by chance started with uncompressed scenario, then filesize will not change and will stay the same but modification time changes.

If that is not your case, then I would say that LZW (lossless compression) generally cannot be better than JPEG (lossy). Also, what do you refer as "Original image"? You should refer raster as original image, e.g. try to write to TIFF without compression – that will be your baseline.
I've got no option but to sell you all for scientific experiments. Or a tiny ad:
