Solution 1

before uploading would mean you want to do that on client side. Putting such a code on client side will impose certain constraints on the users. ideally this should be done on server side so ensure all the dependencies(for whatever method you use for compression are present on server).

If you want to give the illusion that the compression is happening before upload then perhaps some Ajax could help.

Thanks for suggestion.
Actually my purpose is to reduce image or any file (of big size) so that my uploading time will reduce.Hence i willing to do compress at client side only.is it possible?

Try converting the file into binary format and then store it in database.
