How to Choose a Free URL Shortener: 10-Point Checklist

Every free URL shortener looks the same on the homepage: paste a link, get a shorter one. The differences show up later — when you need analytics that aren't paywalled, an alias that isn't taken, or a link that still works next month. Choosing well up front costs ten minutes; choosing badly costs you every link you've already shared.

Here's a 10-point checklist to run any shortener through before you commit.

First, an honest warning: short links can die

A short link only works as long as the service behind it does. Shorteners have shut down over the years, and when they do, every link they ever issued goes dark — in old tweets, printed flyers, and forum posts, all at once. No free service can promise forever, so favor ones that are transparent about their limits and lifetimes rather than ones promising unlimited everything with no visible way to sustain it. If you want the background on how the redirect layer works and why this dependency exists, start with what a URL shortener actually does.

The 10-point checklist

1. Reliability and speed. The redirect adds a hop to every visit, so it must resolve in milliseconds, every time. Test a link from your phone on mobile data, not just your office wifi. Slow or flaky redirects silently cost you visitors.
2. Analytics included, not teased. Click counts, locations, devices, browsers, and referrers should come with every link on the free tier. Ideally the numbers are bot-filtered, so preview crawlers don't inflate them.
3. Custom aliases. You should be able to choose yourbrand-sale instead of x7Kp2q. Readable links earn more clicks and more trust, especially anywhere the URL is visible or typed by hand.
4. QR code generation. Every short link should come with a QR code, so print and packaging use the same tracked link as your digital channels — no separate QR tool required.
5. Safety screening. The service should block malicious destination URLs. This protects your audience and keeps the shortener's domain off spam blocklists — which keeps your links deliverable in email and messaging apps.
6. Transparent limits. How many links, for how long, with what features — stated plainly before you sign up. Clear limits are a sign of a service planning to stay alive; vague "unlimited free" promises often precede a paywall or a shutdown.
7. Link expiry control. Links should expire on your schedule within the service's window, not vanish unpredictably. Expiry is a feature — campaign links shouldn't outlive the campaign — but you need to set the date.
8. App-download routing. If you ever promote a mobile app, one link should route iPhones to the App Store and Androids to Google Play automatically. Bolting this on later with a different tool splits your analytics.
9. No forced paywalls for basics. Shortening, aliases, QR codes, and analytics are table stakes. A free tier that locks analytics or aliases behind payment isn't a free shortener; it's a trial.
10. Data privacy. Measurement should be aggregate — countries, devices, referrers — not personal profiles of the people who click. Read the privacy policy; if the business model is reselling click data, your audience is the product.

Three checks that deserve a closer look

Analytics depth

"Analytics included" ranges from a bare click counter to real reporting. Look for clicks over time, countries and cities, device and browser splits, referrers, and bot filtering — the reports that actually answer "which channel worked?" A shareable analytics page is worth extra credit if you report results to clients or teammates. Link Analytics 101 explains how to read each of these reports.

App download routing

Test the smart-link behavior on three devices: an iPhone should land on the App Store, an Android phone on Google Play, and a desktop browser should get something sensible — a download page with a QR code and store badges, or a direct store redirect. The full comparison in store link vs smart download link shows why this matters the moment your audience is mixed.

Safety and trust signals

Paste a known-bad test into the shortener and see if it's refused. Then check the other direction: does the service's domain have a clean reputation in the messaging apps you use? A shortener that tolerates spam gets its whole domain flagged, taking your legitimate links down with it — are shortlinks safe? covers how to evaluate this from the clicker's side too.

How opn.my answers the checklist

Since you'll want a concrete example to score, here's ours, stated plainly. opn.my is a free URL shortener with click analytics built in: 3 links with no account, 10 with a free account. Every link gets a custom alias option (3–32 characters), a QR code (free login to download), bot-filtered analytics with clicks, locations, devices, browsers, and referrers, plus a public shareable analytics page. App download links route each device to the right store with a per-platform breakdown. Malicious URLs are blocked by safety screening.

The honest limits: links live up to 90 days with configurable expiry, analytics live with the link, links can't be edited after creation, and there are no custom domains or team features. That trade — a smaller, clearly-bounded free service instead of an "unlimited" one — is exactly point six on the checklist. The how-to-use guide shows the whole flow in a couple of minutes.

Run the test yourself

Don't choose from feature tables — choose from behavior. Take your top candidate and spend ten minutes on it:

• Shorten a real URL and time the redirect on mobile data.
• Claim a custom alias and share the link in one channel you actually use.
• Check the analytics the next day for honest, bot-filtered numbers.
• Scan the QR code from a screen and from paper.
• Read the limits page and the privacy policy — all of it.

Any service that passes all five is a keeper. Any service that hides the answers probably just answered you anyway.
