Is that short URL you're visiting REALLY going to contain cute kittens, or instead is it going to mug you and steal your wallet? Unshorten.It! takes any bullets for you, analysing the website for safety and letting you see it before you decide whether to proceed.
URL shortening is a technique on the World Wide Web in which a Uniform Resource Locator (URL) may be made substantially shorter and still direct to the required page. This is achieved by using a redirect which links to the web page that has a long URL. For example, the URL "http://example.com/assets/category_B/subcategory_C/Foo/" can be shortened to "https://example.com/Foo", and the URL "http://example.com/about/index.html" can be shortened to "https://goo.gl/aO3Ssc". Often the redirect domain name is shorter than the original one. A friendly URL may be desired for messaging technologies that limit the number of characters in a message (for example SMS), for reducing the amount of typing required if the reader is copying a URL from a print source, for making it easier for a person to remember, or for the intention of a permalink. In November 2009, the shortened links of the URL shortening service Bitly were accessed 2.1 billion times.
