SHUURL is a URL-shrinking service that adds some security styling to your links, providing everyone who clicks a security rating and thumbnail preview of the page you're linking to. Every URL you shorten with SHUURL is compared to the database at the Web of Trust, a crowd-sourced website rating service. Anyone who follows the URL will stop first at the SHUURL website and see a thumbnail of the site you've linked to alongside its WoT rating. That preview is a nice protection layer, but some images may be too small to tell if its safe for work or not—something you can solve with the more standard TinyURL service by turning on previews. SHUURL is a free service, no sign-up required.
