A URL shortener is a web-based tool or service that takes a long and complex URL (Uniform Resource Locator) and generates a shorter, more manageable version. The purpose of a URL shortener is to make lengthy URLs more user-friendly, shareable, and easier to remember. The shortened URL typically redirects users to the original, longer URL when clicked or entered into a web browser. This redirection is usually achieved through the use of HTTP redirects or JavaScript.
