About this tool
QR codes bridge print and digital: one scan moves someone from a poster, package or business card to your link. This generator builds them locally in your browser with four ready-made modes. Text handles any string; URL validates and encodes a link; WiFi builds the special payload that lets phones join your network without typing the password — perfect for guest rooms and cafes; and vCard encodes a full contact that scans straight into the address book. Size and error-correction controls let you trade density against robustness: higher correction survives print damage and logos, lower keeps codes simple for long URLs. The result downloads as a crisp PNG at your chosen resolution, ready for print or screen. Because generation happens entirely on your device, WiFi passwords and contact details are never transmitted — a meaningful privacy property that most online generators cannot offer. No account, no watermark, no expiry on the codes: they are plain standards-compliant QR codes that work forever.

Frequently asked questions
Do these QR codes expire?
No. They are plain static QR codes encoding your data directly — no redirect service, no expiry, no tracking.
Which error-correction level should I pick?
M (15%) is a good default. Choose H (30%) if you plan to overlay a logo or print small, and L for very long URLs.
Is my WiFi password safe here?
Yes. The code is generated locally in your browser; the password is never sent over the network.
What resolution should I use for print?
Set the size to at least 512 pixels for business cards and 1024 or more for posters, then scale in your layout tool.
