URL Unshortener

Shortened URLs are everywhere — in social media posts, email newsletters, marketing campaigns, SMS messages, and anywhere that long URLs are unwieldy. Services like bit.ly, t.co, and tinyurl.com take a long URL and replace it with a compact one. URL Unshortener reveals the full destination URL before you click, so you know where you're actually going.

The security case for URL unshortening is real and immediate. A shortened URL completely obscures the destination — it could point to a legitimate article, a phishing page, a malware download, or anything else. When you receive a shortened URL from an unknown sender or in an unsolicited message, checking the full destination before clicking is a basic precaution. Phishing campaigns and malware distribution regularly use URL shorteners specifically because they hide the destination.

Privacy is another driver. Some shortened URLs contain tracking parameters that identify you as a specific recipient, record when and from where you clicked, and feed data back to marketing platforms. Unshortening reveals these parameters, giving you the option to remove them before visiting the page if you'd prefer not to be tracked through a specific campaign link.

Technical and research use cases involve following redirect chains to understand how traffic is being routed. When investigating a campaign, auditing link performance, or building tooling that processes URLs, knowing the actual destination (and the redirect path to reach it) is often necessary. URL Unshortener shows the final resolved URL and, where applicable, the intermediate redirects in the chain.
