The link shortener web-based project is a tool that allows users to shorten long URLs into shorter, more manageable links that are easier to share and remember. The project typically involves designing and building a web application that can receive a long URL as input from a user, generate a unique shortcode for that URL, and store the code and the associated URL in a database. When a user clicks on the short link, they are redirected to the original long URL. The project may also include additional features such as analytics tracking, custom URLs, and password-protected links.
