A short URL, also known as a shortened URL or a tiny URL, is a condensed version of a longer web address that redirects to the original URL. It is typically created using a URL shortening service and is used to make long and complex URLs more manageable and shareable. Short URLs are often used in social media posts, emails, and other online platforms where character limits are a concern. They not only save space but also make it easier for users to remember and type in the URL. However, they can also be used for malicious purposes, so it is important to use them with caution and only from trusted sources.
