URL shortener services are online tools that can condense long and complex URLs into shorter and more manageable links. These services generate a new, abbreviated URL that redirects users to the original destination. They have become popular due to their convenience in sharing links, especially on platforms with character limitations like social media. URL shorteners work by assigning a unique identifier to the original URL. When a user clicks on the shortened link, they are directed to the service's website, which then redirects them to the intended destination. This redirection happens instantly, allowing users to access the desired content without any noticeable delay.
