QR Code Guides
Learn how QR codes really work
Clear, simple how-to guides: create and scan codes, pick the right size and error correction, design custom codes, and fix codes that will not scan.
Want to understand QR codes before you print thousands of them? These plain-language guides walk you through how they work and how to get great results every time.
Start with the basics: choose fixed content, create a clear code, then test it on a real phone. Static QR codes do not expire and do not need tracking.
How to Create a QR Code
Creating a QR code is simpler than most people expect. You only need to decide where it points and pick the right file to download.
How to Scan a QR Code
Almost every modern phone can read a QR code straight from the camera, with no extra app to install.
How QR Codes Work
A QR code looks random, but every part of the pattern has a job, from the big corner squares to the tiny scattered modules.
QR Code Best Practices
A QR code only works if people can scan it easily and know why they should. A few simple rules make all the difference.
QR Code Error Correction Explained
Error correction is the safety net built into every QR code, letting it recover data even when part of the pattern is missing.
QR Code Sizes: How Big Should It Be
There is no single correct size, only the right size for the distance people scan from. A simple ratio gets it right every time.
Static vs Dynamic QR Codes
Both look identical, but one is fixed forever while the other can be edited and measured long after it is printed.
Custom QR Code Design
A custom code can carry your colours and logo without becoming unscannable, as long as you respect a few limits.
QR Codes for Print
Codes that scan perfectly on screen can fail in print if the file, resolution or margins are not prepared properly.
QR Code Security and Safety
A QR code is just a link, so the same caution you use with messages and emails keeps you safe when scanning.
QR Code Not Working: How to Fix It
A code that will not scan almost always has a simple, fixable cause, from poor contrast to a tiny size or a dead link.
The Free QR Code Guide
You can create high-quality QR codes without paying a cent, as long as you know what free really includes.
Common questions
Are the QR codes static?
Yes. This generator creates static QR codes that store the link or data in the pattern itself, with no redirect or scan tracking from us.
What should I check before printing?
Test the code at final size on at least two phones. Size, contrast and clear quiet space matter more than decoration.
