I'm not really sure what you are asking, but the answer is probably not or
maybe?

First you will need to get your content into a ByteArray you can then use the
ByteArray compress() method to compress the byte array and then you can use the
various and sundry communications functions to send the compressed byteArray to
whatever server and its backend that you are using.

What are you trying to do? I'm guessing that getting the content into the
bytearray might be the hardest part. How big are these files, what are you
hoping to gain, etc.
