What Is the Difference Between a QR Code and a Short Link?
A QR code is an image a camera reads. A short link is a short URL that redirects to a longer one. Many QR codes contain a short link.

A QR code is an image that a phone camera reads; a short link is a short web address that redirects to a longer one. The QR code changes how people get to a link (scanning instead of typing), and the short link changes what the link looks like and where it is managed. They aren’t rivals: a lot of QR codes contain a short link.
The short version
| QR code | Short link | |
|---|---|---|
| What it is | A two-dimensional barcode | A URL on a short domain |
| How people use it | Point a camera at it | Click, tap or type it |
| Can hold | A URL, plain text, contact details and more | Only a web address |
| Works best on | Print, packaging, signs, screens across a room | Social posts, SMS, email, slides, radio |
| Can be changed later | Only if it holds a redirect (a dynamic code) | Yes, if you control the redirect |
| Can count visits | Only if it holds a redirect | Yes, at the redirect |
The last two rows trip people up. Editing and counting come from the redirect behind the code or link.
What a QR code is
A QR code, Wikipedia explains, is “a type of two-dimensional matrix barcode,” invented in 1994 by Masahiro Hara at Denso Wave to label car parts. DENSO WAVE’s history page says the QR “stands for quick response,” and that the company kept the patent but declared it would not exercise it. That’s why any app or generator can make one for free.
The pattern stores data. That data can be a web address, but it can also be text, a contact card or Wi-Fi login details. When a phone sees a web address in the pattern, it offers to open it. If the address is long, the pattern gets denser, because there’s more to encode.
What a short link is
URL shortening makes a web address “substantially shorter.” You get a short domain plus a key, and visiting it sends you on to the original page. The first service most people heard of, TinyURL, launched in 2002.
Under the hood, it’s a standard web redirect. MDN’s guide to HTTP redirects says redirect responses “have status codes that start with 3” and a Location header holding the new address, and browsers load that address straight away. A permanent move is 301 (or 308). A temporary one is 302 (or 307). For a short link you might repoint later, a temporary redirect fits better, since crawlers don’t treat the new address as a replacement for the old one.
How they work together
Put a short link inside a QR code and you get what’s usually called a dynamic QR code. The printed pattern holds the short redirect URL. The redirect service decides where it goes and logs each visit.
That gives you three things a plain QR code with a long URL can’t:
- Edit after printing. Change the destination on the server and every printed code follows. See dynamic vs static QR codes.
- Count scans. Every scan passes through the redirect, so it can be counted. How to track QR code scans covers what you can learn from that.
- A lighter pattern. A short URL takes less space than a long one with tracking tags, so the squares can be bigger at the same print size.
A real example: a café prints table cards with a QR code for the menu and the short link cafe.link/menu underneath. Diners with a camera scan it. Someone on a phone with a broken camera types the link. The owner edits the menu URL once a season and never reprints the cards.
When to use each
A QR code fits when the reader is looking at something physical with a phone in hand: a table card, a poster, a box, a slide shown in a room. Typing a URL from a poster is slow and error-prone. Scanning isn’t.
If the reader is already on a device, send a short link. That covers SMS, social posts, newsletters and podcast read-outs. Nobody scans a QR code on the phone they’re reading it on. For texts and social posts, custom short links for business covers why a branded domain matters.
On print, put both whenever you have room, each with its own tracking, so you know how many people scanned and how many typed. UTM parameters for QR codes shows how to tag them.
My take
I’d never print a QR code that holds a long, direct URL for a campaign. Put a short link you control inside it. The day the landing page moves (and it will), you fix one redirect instead of reprinting. The only codes I’d leave static are ones whose content never changes, like Wi-Fi details for a router.
The limitation: the redirect is a dependency
Both short links and dynamic QR codes depend on the service doing the redirect. If it stops, every link tied to it breaks. That’s link rot, and Wikipedia notes many shortening services “may not have a sustainable business model in the long term.” A May 2012 study it cites found 61% of URL shorteners had shut down. Even Google’s goo.gl, announced on 14 December 2009, was wound down. In 2024 Google said its links would stop working on 25 August 2025, then later said it would only switch off links with no traffic since late 2024.
QRAnalytica has the same dependency: dynamic codes run through QRAnalytica’s redirect servers. A custom domain for the short links helps, because you can point that domain at another service. It doesn’t remove the dependency. If the service you’re on goes down, your codes go down with it.
Short links also hide where they go. Wikipedia notes a short URL “obscures the target address and can be used to redirect to an unexpected site,” and the same is true of a QR code. How to scan a QR code safely covers what to check.
FAQ
Is a QR code just a link?
No. A QR code is a pattern that stores data, and that data can be a web address, plain text, contact details or Wi-Fi settings. When it stores a web address, the phone offers to open it.
Can a QR code contain a short link?
Yes, and dynamic QR codes work exactly that way. The pattern holds a short redirect URL, and the redirect sends the scanner to the real page, which you can change later.
Which is better for print, a QR code or a short link?
Use both where you can. The QR code serves people with a phone in hand, and the short link printed underneath serves people who prefer to type it or are reading from a screen they can’t scan.
Do short links expire?
Only if the service behind them stops redirecting. Google’s goo.gl, for example, announced in 2024 that its links would stop working, then later narrowed that to links with no recent traffic. If you own the domain and the redirect service stays up, the link keeps working.
Can I track scans and clicks separately?
Yes, if the QR code and the typed link point at different short URLs or carry different tracking tags. Then you can see how many people came from the printed code and how many typed or clicked the link.
