Rahul dai,

upload your pdf to some website, like geocities, ani you can use google translate to convert .pdf file too.

I'm not sure if we can translate it without uploading.

here's an example,

 the following is a korean version of pdf file

http://www.health.nsw.gov.au/mhcs/publication_pdfs/6970/DOH-6970-KOR.pdf

using google translate, following is the english version

http://translate.google.com/translate?u=http%3A%2F%2Fwww.health.nsw.gov.au%2Fmhcs%2Fpublication_pdfs%2F6970%2FDOH-6970-KOR.pdf&hl=en&ie=UTF-8&sl=ko&tl=en

If its not top secret, forward it to me, i'll try to see if its possible to do the same way.
