FocoLink

FocoLink is a small program that auto-shortens any URL you copy to your clipboard.

The program stays minimized in your system tray, and whenever you copy a URL it sends a popup saying the link is being shortened. In seconds the address on your clipboard gets replaced with a much smaller one.

Unfortunately the application runs a bit short on other options. It's got a link history for you to check out, and really not much else. Even still, that might be one of FocoLink's strong points: it's ideal for helping people who don't know much about software crop their URLs quickly and almost without lifting a finger.
