Frequently asked Questions
Are QR Codes for free?
Yes, the term QR Code (QR = Quick Response) itself is a registered trademark of Denso Wave Incorporated, but the use of QR codes is free.
The QR Codes that you create on our website can be used free of charge and commercially and you can create as many static QR codes as you want.
You can learn more about the history of QR Codes here: https://www.qrcode.com/en/history
I have already created and printed my QR Code. Can I change the URL of my QR Code?
Yes, in a dynamic QR Code you can change the destination URL at any time.
Static QR Codes have the destination address is permanently entered and the URL can
not be changed after creation.

static versus a dynamic QR Code.
Do my QR Codes expire?
Static QR Codes never expire since the target URL is encoded in the QR Code and you will be redirected to the URL directly.
Dynamic QR Codes in your free account will never expire, except you
will delete the QR Code yourself or the target URL is redirecting you
to an expired website. Our
broken link checker will always
keep you informed if your QR Codes are working.
After the evaluation period on one of our paid subscription plans, your account will be deactivated and therefore your QR Codes will stop working
if you do not subscribe.
However, once subscribed your QR Codes will not expire if you have been a customer for at least one year and if you have no pending invoices.
Are you displaying ads or banners when scanning a QR Code?
No, we do not display any ads.
Our platform does not show ads in any context.
What you are probably seeing are ads from your QR Code scanner application.
Some developers create QR Code readers that display adds while scanning the QR Codes.
This is a really bad experience for the user.
Here you will find free, fast and robust alternatives that will make scanning a better experience with no ads.

What is the minimum size of a QR Code?
A QR code with a length of up to 72 characters (this is the length of a typical URL) should be printed in a
size of 2 x 2 cm when scanned from a distance of 20 cm.
Theoretically, smaller sizes of 1 x 1 cm are possible on modern smartphones with a camera that supports autofocus.

Is a QR Code still readable when some areas of the QR Code are damaged?
When creating a QR Code, a certain level of error correction
can be specified so that the code stays readable,
even if the QR Code is partially damaged or hidden.
There are 4 different levels:
- Level L - up to 7%
- Level M - up to 15%
- Level Q - bis 25%
- Level H - up to 30% may be damaged
The higher the error correction, the more the QR code can be damaged,
but the bigger is the size of the QR Code.
