Unmasking Shortened Links

February 27, 2023

Web links are great, when you’re on the web. But if you need to read off or write down a web address, or URL, to someone else, anything beyond a simple domain name is going to be way too complicated. Ideally, you want something short and memorable. Enter link-shortening services like Bitly, Owly and others. These services convert long, ugly URLs to short, simple, memorable links. Unfortunately, this also obscures the actual link. When you click a shortened link, you have no idea where it will take you. Today, I’ll give you some tools that will allow you to determine the final destination and even see an image of the site without actually going there.
