Frequently asked questions
Is the QR Code Generator really free?
Yes. Every QR code and design is generated locally in your browser with a maintained JavaScript library. Your content is never uploaded to our servers — there is nothing to upload to.
Do I need to create an account to use the tools?
Yes — all five tools (QR Code Generator, QR Design Studio, vCard Generator, Link-in-Bio Builder and UTM Link Builder) are free to use with no account and no sign-up.
Do the QR codes expire?
Yes. We generate static QR codes: the data is encoded directly into the QR pattern itself, so the code works forever, needs no subscription, and keeps working even if this website ever went offline.
Can I download and print the QR codes?
Yes. PNG downloads are standard image files and the Design Studio can export genuine vector SVG files. Both contain exactly the data shown in the preview. Always test a scan with your phone before printing.
Is my uploaded logo or contact data sent to a server?
Absolutely. All image processing — including optional logo uploads — happens locally in your browser via the FileReader API. Files are never sent to a server.
How do I scan a QR code with my phone?
Modern phones (iPhone and most Android devices) scan QR codes directly with the built-in camera app — no extra app needed. If scanning fails, check size, contrast and lighting; our scanning-troubles guide walks through the common fixes.
Does the Link-in-Bio Builder host my page online?
No. The builder gives you a live preview and lets you download a standalone HTML file (or a JSON configuration) that you upload to your own hosting. We never invent a public URL for your page.
What are UTM parameters and do they track clicks by themselves?
UTM parameters are labels added to a URL (like utm_source=newsletter) so analytics tools such as Google Analytics can tell you where visitors came from. Adding them doesn't track anything by itself — the destination website must have analytics installed.
