URL Shortener

Long URLs are ugly, impossible to remember, and often get truncated in social media previews or print materials. Short links solve all three problems — they take a minute to create, fit anywhere, and their redirect can carry tracking parameters invisible to the user. This URL shortener creates short links with custom aliases, automatic QR code generation, and templated UTM parameters so your social shares and marketing campaigns have clean attribution.

The core flow is paste-and-shorten. Drop a long URL, optionally provide a custom alias (so toolrs.com/launch instead of a random hash), and click. The resulting short link redirects to the original URL with a 301 or 302 depending on your choice. A QR code is generated automatically so you can print posters, conference materials, or product packaging that link back through the short URL and keep your tracking.

Beyond simple shortening, the tool has marketing-minded features. UTM parameters (source, medium, campaign, term, content) can be added to the destination URL through a template so every shortened link in a campaign gets consistent tracking. Branded short domains work if you configure one. Analytics showing click counts and referrer breakdown help you learn what's working. For privacy, the tool never stores the destination URL in plain text on a shared database — it uses ephemeral links when you want them, persistent links when you need them.

A URL shortener works by mapping a short token to a long URL in a database, then running a redirect server that takes the short token path, looks up the long URL, and sends an HTTP redirect response. The short token is typically 5-8 alphanumeric characters (base62 encoded: 0-9a-zA-Z) giving billions of unique combinations even in a short space.

Redirect behavior matters. A 301 "Moved Permanently" redirect is cacheable and signals to browsers and search engines that the link should always resolve to the target. A 302 "Found" redirect is non-cacheable and used when you might change the destination later (product launches, A/B tests). This tool lets you pick per link.

Custom aliases trade uniqueness for memorability. A custom alias like /launch is easy to type on a live stage or say on a podcast; a random hash /xY3k2p is not. The tool reserves custom aliases while keeping random-token generation for bulk use.

QR code generation uses the short URL as payload, which means the resulting QR is small and easy to scan — a real advantage over encoding the long URL directly. UTM parameters are appended to the destination URL, so when users click through, your analytics tools see the attribution. For privacy and safety, links can be set to expire, password-protected, or set to one-time use. Rate limits prevent abuse. Malicious URL detection screens destinations against known phishing and malware lists before creating a short link.

Commercial shorteners like Bitly offer robust analytics but gate advanced features behind paid tiers. Native platform shorteners (Twitter's t.co) work only within that platform. Browser extensions shorten but lack custom aliases and QR codes. This tool combines shortening, custom aliases, QR generation, UTM templating, and analytics in one browser-based interface — free, privacy-conscious, and simple.
