Frequently Asked Questions
Twitter's t.co shortener often uses JavaScript redirects that simple expanders can't follow. Our tool detects HTTP redirects, meta refresh tags, AND JavaScript-based redirects to successfully expand all t.co links and other modern shorteners.
We use multiple shortening services with automatic fallback. First we try TinyURL, then Is.gd, Os.db, and others. If one service fails, we automatically try the next to ensure your URL gets shortened successfully.
Our tool detects three types of redirects: HTTP redirects (301, 302, 303, 307, 308), meta refresh redirects, and JavaScript-based redirects (window.location, document.location, location.replace, etc.).
Our tool can trace up to 15 consecutive redirects, which covers virtually all legitimate URL shorteners and most redirect chains. We also include protection against redirect loops.
