Create a QR code by choosing what it should do: share a Wi-Fi network without typing the password, open a WhatsApp chat with a pre-filled message, add a contact to the address book, or open a link. Style it with your colors, module shapes, a gradient and a logo — every style is verified by re-reading the rendered pixels with the same decoder a phone uses, so a fragile style is flagged before printing. Export a high-resolution PNG, an SVG, or a ready-to-print “Scan me” poster.

How to create a QR code in 3 steps
Choose a use, not a format
Pick what the code should do — Wi-Fi, WhatsApp message, contact card, call, SMS, email, link, or a hosted business card — and fill in two or three fields.
Style it, with proof
Colors, module shapes, rounded eyes, gradient, logo: after each change, the rendered pixels are re-read with a real decoder. A style that scans gets its badge; a fragile one is flagged — and nothing is blocked.
Export or print
Download a high-resolution PNG or an SVG, or generate a ready-to-print “Scan me” poster with your headline. You can also scan any QR code with the camera or a photo — nothing opens automatically.
Why use this QR code generator
- Wi-Fi without typing the password, WhatsApp with a pre-filled message, a contact that joins the address book: the right format so the phone offers the right action directly.
- A pretty QR code that does not scan is worthless. Each style is checked by decoding the rendered pixels — the badge tells you it scans, and a risky style is flagged instead of silently failing on a poster.
- A QR code is frozen: change your number and printed cards die. The hosted business card avoids that — its QR carries a stable address, and you edit what the page shows whenever you want.
- Generation and scanning happen in your browser; neither your content nor your camera goes to a server. Two announced exceptions: the business card and the dedication live on a hosted page — that is what makes them editable and lets them carry a photo.
Frequently asked questions
Is the QR code generator free?
- Yes — creation, styling, verification, the printable poster and the PNG/SVG exports are free, without an account.
Do these QR codes expire?
- A classic QR code encodes its content directly, so it keeps working as long as it is printed — there is nothing to expire on our side. The hosted business card is different by design: its QR points to a page that stays editable.
Will my styled QR code actually scan?
- That is exactly what is verified: after every styling change, the rendered pixels are decoded with the same library a scanner uses, and the result must match the content exactly. The badge says it scans; a fragile style is flagged.
Can I put my logo in the QR code?
- Yes — and the verification runs on the final result, so you see immediately whether the code still scans with the logo in place.
Can I update a business card after printing it?
- Yes: the hosted card's QR carries a stable address, so you can change the number, photo, links or WhatsApp later — cards already printed keep working, and the contact file stays downloadable.
Does the scanner open links automatically?
- Never. The scanner shows what it read — the domain of a link, a copyable Wi-Fi password, a downloadable contact — and you decide what to do.
