A URL shortener is a tool that converts a long URL (Uniform Resource Locator) into a shorter, more manageable link. This is done by creating a new, shorter URL that redirects to the original, longer one.  

Why use a URL shortener?

• Easier to share: Shortened URLs are easier to remember and share, especially on social media platforms with character limits.  
• Cleaner appearance: They make your links look more professional and less cluttered.  
• Track clicks: Many URL shorteners offer analytics tools to track how many times your link has been clicked and where the clicks are coming from.
