What is a QR Code?
A QR code (Quick Response code) is a two-dimensional barcode that can be scanned by any smartphone camera to quickly open a URL, display text, add a contact, connect to Wi-Fi, or trigger other actions. They were invented in 1994 by a Japanese automotive company and have become ubiquitous on business cards, menus, posters, product packaging, and marketing materials.
This generator creates QR codes entirely in your browser — no server is involved. The generated QR code is yours to download and use without watermarks or restrictions.

Frequently Asked Questions
On iPhone: open the Camera app, point it at the QR code, and tap the notification that appears. On Android: most phones scan QR codes directly from the Camera app; some require using Google Lens. No separate app is needed on modern smartphones (iOS 11+, Android 8+). The QR code doesn't need to fill the entire viewfinder — just hold it steady.
A standard QR code can hold up to 4,296 alphanumeric characters or 7,089 numeric digits. However, more data means a denser, harder-to-scan code. For best scanning reliability, keep URLs under 300 characters. If you're linking to a long URL, use a URL shortener like bit.ly first, then generate a QR code from the shortened URL.
QR codes themselves never expire — the pattern is permanent. However, if the QR code contains a URL that eventually goes offline or redirects elsewhere, the code will no longer work as intended. QR codes generated by third-party services that use short links (tracking QR codes) can expire if the service cancels your account. QR codes made here are static and permanent — they embed the actual URL directly.
Yes — use the color picker in this tool to change the QR code color. The most important rule is maintaining sufficient contrast between the code and its background. Dark code on a light background works best. Avoid light colors on white backgrounds, and never invert to light code on a dark background without testing — many scanners struggle with inverted QR codes.
The minimum recommended size for a printed QR code is 2 × 2 cm (about 0.8 × 0.8 inches). At this size, scanners can reliably read it from 20 cm away. For a billboard or large poster, scale proportionally — a code on a 3-meter billboard should be at least 30 × 30 cm. Always test your printed QR code before mass printing.
