Turn a URL, text, WiFi password or contact card into a QR code and print it on a storefront or business card — one scan opens the link or joins the network, far faster than typing. The tool supports four content types: plain text/URL, WiFi (scan to connect, no password typing) and vCard (scan to save to contacts), with customizable size, foreground/background colors and error-correction level; download the PNG when done.
Is the generated content uploaded?
No. QR codes are drawn onto a Canvas by a local JS library in your browser; content is never sent to any server, so even passwords are safe to use.
Which error correction level?
L(7%), M(15%), Q(25%), H(30%) indicate how much of the code can be covered while remaining scannable. M suits most uses; if you plan to place a logo in the middle, choose H and increase the size a bit.
The code won't scan — what now?
Usually the size is too small or the content too long, making the dot grid too dense. Try a larger size (400px+), a lower error-correction level, shorter content, or higher contrast between foreground and background (avoid light-on-light).
