What is a Url Shortener?

Have you ever clicked on a link that looked like “t.ly/demo”? If so, you’ve already experienced what a URL shortener does, even if you weren’t aware of it at the time. URL shorteners are tools that take those long urls and shrink them down into short URLs. The long URL is stored in a database and the software does a redirect by looking up the short URL and finding the long URL. It happens in milliseconds and most people dont even realize the redirect happened.

Why Shorten a URL?

URLs can get long with query strings and parameters. These parameters are needed for the webpage to load correctly but a short URL doesn’t need them since it will handle the redirect. A short URL is easy for an end user to type or remember which means it’s great for marketing content.

How Do They Work?

A url redirect is really a simple concept. When you use a URL shortener, the service creates a tiny link that points to the original, longer URL and saves it in a database. Behind the scenes, it sets up a “redirect,” which is basically an instruction telling anyone who clicks on the short link to quickly hop over to the real destination.

Let’s say you have a super-long link like: https://www.example.com/blog/categories/how-to-guides/url-shortening-basics

A URL shortener might compress it into something like: t.ly/example

Both links get you to the same webpage, but the second one is much easier to share.

Have You Clicked One Before?

Chances are you already have—maybe in a tweet, a text message, or inside an email newsletter. You clicked on a short link, ended up on a longer page, and barely noticed anything happening in between. That moment of “in-between” is the redirect at work and it happens in milliseconds.

Benefits Beyond Shortening

Many URL shorteners also offer extra features like analytics. That means you can track how many people clicked your link, where they’re from, and more. This is great for businesses that want to see how their content is performing.

A Word of Caution

Short links can also hide where they’re really taking you, which is why some people are cautious about clicking them. This is why we built a URL Expander tool that will inspect any URL tell you where it redirects and warn you if it’s potentially dangerous. It’s always good to know where a link leads!

In the end, URL shorteners aren’t magic—they’re a simple (but clever) way to make links more convenient for sharing. The next time you see or share a short link, you’ll know exactly what’s happening behind the scenes. It might just look like a random string of letters and numbers, but there’s really just a redirect behind the scenes.
