How to Shorten a URL: The Complete Guide

You have a long, ugly URL and you need it short. Here is the whole process, and it works the same on Flyn, TinyURL, Bitly, or any other shortener worth using.

The four steps

1. Copy the long URL from your browser's address bar. Grab the entire thing, including the https:// and any parameters after the ?.
2. Paste it into the shortener. On the Flyn homepage, the input is the first thing on the page. No account, no credit card.
3. Click Shorten. You get back a link like flyn.to/x7Kq2.
4. Copy and share it. The short link behaves exactly like the long one: anyone who clicks lands on your original page.

Free without an account, permanent with one

That is genuinely all there is to the mechanical part. Anonymous links created this way on Flyn stay live for 30 days; create a free account and they are yours permanently, with click stats included.

A shortened URL is not a compressed version of your link. It is a brand-new, tiny URL that redirects to your original one. Understanding this single fact explains almost everything else about short links.

The redirect, step by step

When you shorten https://yourstore.com/collections/spring?utm_source=newsletter, the shortener saves that full URL in its database and assigns it a short code, say x7Kq2. When someone clicks flyn.to/x7Kq2, their browser asks Flyn's server for that page, the server looks up the code, and answers with an HTTP 301 redirect pointing at your original URL. The browser follows it automatically. The visitor sees nothing but a fast hop.

Why this design is a feature, not a hack

Because every click passes through the short domain first, the shortener can do useful work in that millisecond: count the click, record country and device, run an A/B split, route mobile visitors to an app, or let you change the destination later without touching the link you already shared. None of that is possible with a raw URL. The redirect layer is the whole product.

Want to see the machinery yourself? Paste any short link into the URL Expander and it shows you the full redirect chain and final destination without you having to click anything.

"Paste into a website" is the obvious route, but it is one of five. Which one fits depends on how many links you make and what happens after the click.

The browser extension route

If you shorten more than a couple of links a week, the copy-switch-tab-paste loop gets old. The Flyn Chrome extension shortens the page you are currently viewing in one click and puts the short link on your clipboard. Searches like "how to shorten a URL in Chrome" are really asking for this.

Bulk and API

Migrating a spreadsheet of product links or generating a short link for every row in your CRM is not a copy-paste job. Flyn supports CSV import and bulk operations on paid plans, and the REST API creates links programmatically: one POST to /api/shorten with your API key returns a short URL in JSON. Zapier-style automations sit on the same endpoint.

The random code a shortener hands you (x7Kq2) is short, but it is also meaningless. Almost every "how do I rename a URL link" question is solved by the custom slug: you choose the part after the slash.

Random code vs readable slug

• flyn.to/x7Kq2 tells the reader nothing.
• flyn.to/spring-sale tells them exactly where they are going, and that you put care into the link.

On Flyn you set the slug in the same form you paste the URL into; with a free account every link can have one. Three rules make slugs work harder.

The three slug rules

• Keep it short and readable: two to four words, hyphens between them. The free Slug Generator turns any headline into a clean slug.
• Make it match the destination. A slug that says /pricing should land on pricing. Mismatches feel like bait and erode trust instantly.
• Keep it evergreen. Avoid years and dates in slugs you will reuse, so /black-friday works every November without edits.

Every example so far used a shared domain. The next level is a branded short domain you own, like go.yourbrand.com or l.yourbrand.com, with every short link carrying your name instead of a shortener's.

Why branding a link pays

This is not cosmetic. Branded links consistently earn higher click-through than generic ones (the data we collected in why branded short links increase CTR puts the lift around 30%+), because the reader can verify the source before clicking. The same property keeps your links out of trouble: shared shortener domains carry the reputation of everyone using them, which is exactly how short links end up flagged as spam. Your own domain carries only your reputation.

Setting one up takes minutes

On Flyn you add a subdomain like go.yourbrand.com under Pro, point one CNAME record at Flyn, and SSL is provisioned automatically. From then on every link you shorten can use it. If you currently pay Bitly for this, compare notes with our alternatives hub or the Bitly migration guide; branded domains are the single feature where pricing differs most across shorteners.

The shortest way to say it: a generic short link borrows someone else's reputation, a branded short link builds yours. Every click you send through go.yourbrand.com is a tiny deposit in your own name.

Shortening without tracking is leaving the best part on the table. Because every click passes through the redirect, a good shortener can answer the questions a raw URL never can: how many people clicked, from where, on what device, coming from which site.

The two-layer tracking setup

The professional pattern combines two tools that answer different questions:

• Short-link analytics count and segment the click itself. Flyn counts every click on every link, free plan included, and Pro segments them by country, device, and referrer. Our guide to tracking clicks on a link covers reading these numbers.
• UTM parameters tell your website analytics where the visitor came from, surviving all the way into GA4 or PostHog. Build them with the free UTM Builder, then shorten the tagged URL. The full recipe lives in the ultimate UTM guide.

Order matters: add UTMs first, shorten second. The parameters hide inside the short link and reappear at the destination. Verify any link survived the round trip with the UTM Parser.

The mechanics are easy, which is exactly why the mistakes are so common: nobody thinks a 30-second task can go wrong. These are the ones that cost real clicks.

Mistakes that cost clicks

• Shortening the wrong URL. Test the long URL in a private window first. If it 404s, requires a login, or redirects, fix that before shortening. The Broken Link Checker catches dead destinations across a whole page.
• Random codes in human-facing places. Slides, print, podcasts (show notes especially), and live talks need readable slugs. Nobody can type x7Kq2 from memory.

Mistakes that cost trust

• Generic domains in cold email. Spam filters score the link domain, and shared shortener domains carry strangers' baggage. Branded domains are the fix, as covered above.
• Forgetting links can expire. Anonymous links often have a shelf life, and that is sometimes the point: the Expiring Link Generator makes self-destructing links deliberately. For permanent links, use an account.
• Never auditing old links. Destinations rot. A quarterly pass with the Bulk Health Checker finds short links whose destinations have died since you shared them.
• Ignoring what happens on the other side. Recipients increasingly check links before clicking, and you should make that easy, not hard. How they check, and how to be the sender whose links pass that check, is the subject of our companion guide on short link safety.

Avoid those six and you are ahead of most professional marketers. The full toolkit, from QR codes to rotating links, lives in the free tools library.
