Frequently asked questions
The questions that come up most often, answered in full. If yours is not here, the two pages on static and dynamic codes cover the choice that matters most.
Is the generator free?
Yes. All fourteen QR code types can be generated, customised and downloaded free of charge, in any number and with no watermark. There is no time-limited trial: static codes do not even need an account.
Do I need to sign up to create a QR code?
Not for static codes: create, customise and download them with no account and no limits. Dynamic codes do need one, because the short address, the redirect and the analytics live on our servers and need an owner. The free plan is enough — it is a sign-up, not a subscription.
What is the difference between a static and a dynamic QR code?
A static QR code carries the information inside itself and works offline, but cannot be changed. A dynamic QR code carries a short address: the destination it points to can be changed at any time without reprinting, and every scan is counted.

Can I change the destination after printing the QR code?
Yes. The printed code always points to the same short address: change the destination from the panel and anyone scanning lands on the new content, with nothing to reprint.
Which formats can I download the QR code in?
PNG at 1024 or 2048 pixels for web and print, vector SVG for lossless enlargement, and JPEG for lighter files. The file you download is exactly what the preview showed, frame and logo included.
Can I customise colours, shapes and logo?
Yes: six module shapes, corner marker style and colour, background colour, three frames with editable text and a logo picked from twelve icons or loaded from an address. The preview updates as you choose, with no page reload.
Will the QR code still scan after I customise it?
The generator watches that for you: it warns when the contrast between modules and background drops below the level at which optical readers start to fail, when the modules are lighter than the background, and when the chosen shape is one that stricter decoders struggle with. Before a large print run, test it with two different phones anyway.
Do QR codes expire or stop working?
No, the codes you generate never expire. If the owner deactivates a dynamic QR code, anyone scanning it sees a notice page instead of the destination.
What analytics do I get on scans?
For every dynamic code: scans day by day, unique visitors, device type, country and city of origin, and the latest reads with the redirect response time. The dashboard shows the same figures across all your codes, compared with the previous period.
What happens to the data of people who scan?
We record the time of the scan, the device type and the approximate geographic origin, and nothing else. The IP address is never stored in the clear: it is used only to derive country and city, and is made unrecognisable before being written. Whoever scans has nothing to install and nothing to accept.

The choice that matters most is between static and dynamic codes: the two dedicated pages explain it in full, with the strengths and limits of each mode.
