Drop pdf file to sharepoint in asp.net

Question

what's the best way to accomplish this task? (new to sharepoint)

Do we need to install sharepoint on webserver in order to use sharepoint.dll/spsite object or just adding the reference to sharepoint.dll in asp.net is sufficient ?

If yes then what features of sharepoint need to be installed?

TIA
