Free QR Code Tools
Handy helpers for the jobs around a QR code: check what a code contains, find the right print size and prepare the link before you turn it into a code. All free, no sign-up.
Tools for every step before printing
A good QR code starts with a good link and ends with a code that people can actually scan. The QR code reader shows what an existing code contains, from an image or a screenshot. The print size calculator tells you how large to print a code for the distance people will scan it from.
Before you create the code, prepare the destination. The WhatsApp link generator builds a chat link with a pre-filled message, and the UTM builder adds campaign tags so your web analytics shows which poster or flyer brought the visit.
When the link is ready, paste it into the free generator – or create a dynamic code in your account to see scan statistics next to your UTM data. Whatever you create, test the code with at least two different phones before it goes to print.
Are these tools really free?
Yes. All tools on this page are free to use and don't require an account or an email address.
Can I read a QR code without a phone?
Yes. Upload an image or screenshot to the QR code reader and it shows the content, so you can check a link before you open it.
How big should I print my QR code?
It depends on the scanning distance and the amount of content. The print size calculator gives a minimum size, and our print size guide explains the rules behind it.
Why add UTM tags to a QR code link?
UTM tags tell your web analytics which campaign, medium and source a visit came from, so printed campaigns show up separately from other traffic.
Turn your link into a QR code.
Use the free generator, or create a dynamic QR code you can edit and track after printing.
