compress BitmapData

i am rendering a BitmapData from my webcam and sending the rendered ByteArray (i cant compress using ZLIB because its not running on AIR) file as binary to a server side. problem is each JPEG picture is around 40kb and it needs to be compressed a bit. now i am not talking about resizing the image, just making the file size smaller. anyone know how to do this?

Why not encode to jpeg on the client and just send the compressed image?

yeah, thats what i wound up doing at the end because i was encoding as PNG before, the only downturn is that there is only 1kb of difference between minimium and maximium quality.
