URL Shortener Info

URL shortening requires storing the long URL on a server and issuing redirects - it can't be done purely client-side. Services like TinyURL and Bitly maintain databases that map short codes to original URLs. This page helps you prepare URLs for shortening by stripping unnecessary tracking parameters.

Tracking parameters like utm_source, fbclid, and gclid are added by marketing platforms and social media to track clicks and campaigns. They make URLs long and can contain personal data. Remove them before sharing unless you specifically need to track campaign performance.

A shortener stores the long URL in a database and generates a short code (e.g., bit.ly/abc123). When someone visits the short link, the service looks up the code and redirects to the original URL using a 301 (permanent) or 302 (temporary) HTTP redirect.

You're trusting the shortening service to maintain the redirect permanently and not insert malware, trackers, or ads. Preview short links before clicking using a link expander. For your own links, consider using a custom domain with your own shortener for brand consistency and trust.

For casual use, TinyURL (free, no account). For analytics and branded links, Bitly or Rebrandly. For custom domains, Short.io. For the simplest experience, is.gd supports custom slugs without registration. All services listed on this page are free-tier options.
