You can use a second or third argument to Import and Export. I think
this should work (I tested it with a pdf file from the web):

Export[filename,Import[url,"Binary"],"Binary"]

I'm not sure whether this code and using mathematica in general is the
most effective way to solve this kind of problems, though...
