Free QR Code Generator

What you can use this for

• Links on posters, flyers, signage

  Print-quality codes that scan from a meter away. Use SVG so they stay sharp at any print size.

• Guest Wi-Fi for cafés, Airbnbs, offices

  Tape it inside the menu, in the welcome book, or next to the entrance. Guests scan once, the phone joins automatically, nobody asks staff for the password.

• Menus, schedules, location pages

  Send people from a printed surface to the live web page: event programs, restaurants, exhibit floor plans.

• Business cards and event badges

  Link to your portfolio, LinkedIn, or contact page. Higher ECC levels let small printed codes survive smudges.

FAQ

Is this free?

Yes. No signup, no watermark, no ads, no tracking, no email gate. We built it because we wanted a QR generator that wasn't full of upsells.

Do you store anything I enter?

No. The QR is generated entirely in your browser. Nothing is uploaded, logged, or stored. Disconnect from the internet after the page loads and it still works.

What's error correction level (ECC)?

How much damage the QR can take and still scan. L tolerates ~7%, M ~15%, Q ~25%, H ~30%. Higher ECC makes the code denser. M is fine for digital; use Q or H for printed or weather-exposed codes.

PNG, SVG, or PDF: which should I download?

SVG for anything printed or resized: it stays sharp at any size. PNG for digital use where you need a fixed pixel size (social posts, in-app images). PDF for print shops that want a ready-to-print page sized to the physical dimensions the slider previews.

Do Wi-Fi QR codes work on iPhone and Android?

Yes. iOS 11+ and Android 10+ recognize the standard Wi-Fi format natively. Open the camera, scan, tap 'Join Network'. Older phones can use any QR scanner app. Special characters in passwords are escaped automatically.

Do QR codes expire?

No. Our codes are static; they contain your text or URL directly, so as long as the URL stays live, the QR keeps working forever. Dynamic codes that redirect through a third-party service can stop working when the service shuts down; we don't make those.

What size should I print my QR code at?

At least 2 cm × 2 cm (about 0.8 inches) for reliable scanning. Bigger is more forgiving. The size slider shows the approximate print size at 300 DPI so you can pick the right pixel resolution for your medium.

Why isn't my QR scanning?

Usually one of three things: the printed size is below ~2 cm, the foreground and background colors are too close in brightness, or the text is too long for the chosen ECC level. Try a larger size, darker foreground on a lighter background, or shorter content.

Can I use these QR codes commercially?

Yes. QR codes are an open standard. Denso Wave released the patent royalty-free in 2002, so you can use, print, sell, and modify any code you generate here without any license.
