QR codes have become one of the most practical tools for sharing information quickly — whether you are a business owner, a freelancer, or simply someone who wants to share a link without typing it out. Creating one takes less than a minute, costs nothing, and requires no technical knowledge whatsoever. Here is everything you need to know about creating a QR code in 2026, from the basics to getting the most out of it.
What Is a QR Code?
A QR code — short for Quick Response code — is a two-dimensional barcode that stores information such as a URL, text, contact details, or Wi-Fi credentials. When scanned with a smartphone camera, it instantly opens the stored content without the user having to type anything.
QR codes can store significantly more information than a standard barcode and can be read from any angle, which is why they became the default format for contactless interaction across industries — from restaurant menus and event tickets to product packaging and marketing campaigns.
What Can a QR Code Link To?
Before creating a QR code, it helps to know what you want it to do. Common uses include:
- A website URL or landing page
- A contact card (vCard) with your name, phone number, and email
- A Wi-Fi network — so guests can connect without a password
- A Google Maps location
- A plain text message or instruction
- An app store download link
- A social media profile
- A payment link
For most people, linking to a URL is the most common and versatile use case.

How to Make a QR Code That Actually Gets Scanned
Generating a QR code is straightforward. Getting people to scan it takes a little more thought.
Design it to stand out A plain black-and-white QR code blends into the background. Customising the colours to match your brand makes it look intentional and professional — which increases trust and encourages scanning.
Always include a call to action Never place a QR code without telling people what they will get when they scan it. “Scan to get 10% off”, “Scan to watch the demo”, or “Scan to book a table” all perform significantly better than a bare code with no context.
Get the size right For print materials, a QR code should be at least 2 cm × 2 cm to scan reliably. For posters or signage viewed from a distance, scale it up accordingly — a code on a window display needs to be much larger than one on a business card.
Test before you print Always scan your QR code yourself before committing to a large print run. Check that it opens the correct destination and that the link works on both iOS and Android.
Use tracking to measure performance A trackable QR code tells you how many people scanned it and when. This is invaluable for measuring the effectiveness of print campaigns, comparing different placements, and making data-driven decisions about where to put your code next.

Many QR code generators charge a monthly subscription for features like custom colours, scan tracking, and high-resolution downloads. Nesdzo’s QR Code Generator offers all of these for free — custom design, scan tracking, and downloadable images — with no sign-up required.
