Frequently asked questions
What can I encode in a QR code with this tool?+
Any plain text works, including URLs, Wi-Fi credentials strings, plain messages, or contact card (vCard) text — the QR standard supports arbitrary text content.
Will custom colors reduce scannability?+
Keep good contrast between the foreground and background colors. Low-contrast combinations (e.g. light gray on white) can make the code harder for some scanners to read reliably.
What size should I use for print materials?+
For print, generate at a higher pixel size (512px or more) so the QR code stays crisp at the physical size you need; screens can use smaller sizes like 256px.
Do these QR codes expire?+
No, the QR code itself is a static image encoding your exact text — it doesn't expire or depend on any external service to keep working, unlike some 'dynamic' QR services.
Can I use the downloaded QR code commercially?+
Yes, the generated PNG is yours to use freely, since it's created entirely from the QR code standard using an open-source library, with no watermark or licensing restriction.
Is my content sent to a server to generate the code?+
No, QR encoding happens entirely in your browser using JavaScript — the text you enter is never transmitted anywhere.
