WHAT IS A QR CODE?
A QR (Quick Response) code is a 2D barcode that stores URLs, text,
contact info, WiFi credentials, and more. Any smartphone camera can scan
it instantly — no app required.
This generator runs entirely in your browser. No data is sent to our servers,
no account is needed, and there are no usage limits.
Generate and download as many QR codes as you need, completely free.

FREQUENTLY ASKED QUESTIONS
Q: Is this QR code generator free?
Yes, completely free. No account, no sign-up, no credit card. Generate and download unlimited QR codes with no restrictions, forever.
Q: Do QR codes generated here expire?
No. QR codes are static image patterns — they never expire on their own. They will keep working as long as the destination URL or content they encode remains active. A deleted webpage makes the QR "dead," but the QR code image itself is permanent.
Q: Can I use these QR codes commercially?
Yes. QR codes generated here are completely free for personal, commercial, or non-profit use — restaurant menus, business cards, event posters, product packaging, anything you need.
Q: Does this tool store or share my data?
No. Everything runs entirely in your browser using JavaScript. Your URLs, text, WiFi passwords, and any input are never transmitted to any server, never logged, and never stored anywhere. Closing the tab permanently discards all inputs.
Q: What is error correction level (L / M / Q / H)?
Error correction lets a QR code be scanned even when partially damaged or covered. L = 7% recovery, M = 15%, Q = 25%, H = 30%. Use M for most use cases. Use H if you plan to print on a curved surface or overlay a logo in the center of the QR.
Q: Why isn't my QR code scanning?
Common causes: (1) Data too long — keep URLs short or use a URL shortener first. (2) Low contrast — use the CLASSIC preset for maximum readability. (3) Custom colors with similar brightness levels. (4) Print quality too low — use LARGE size and high-DPI printing settings.
