Long URLs is the full address. But you can make custom ‘shorthands’ for those long addresses, e.g. if every character counts. It requires an additional lookup when the URL is accessed again, but that is often no issue at all. There are several suppliers of this service: e.g. goo.gl, bit.ly, tinyurl.com, is.gd (open to all), and some community-restricted ones (e.g. LinkedIn, Ow.ly). (If you have your own domain and server, you could probably install something similar for yourself.)

E.g. http://bit.ly/2DeFuF1
