better than dropbox for getting pdfs from mac to ipad

i download a lot of magazines and the easiest way to get them onto my ipad that ive found is to drop them into dropbox or box.com folders and then use the dropbox app/box.com app to download them when i want them.

it works well but its slower than it needs to be coz even though my ipad is 5 foot from my mac, its downloading from the internet.

any easy way to do a similar thing but have the files just transfer by wifi from mac to ipad rather than via the cloud?
