Coupon & one-time message tip
Need expiry or tracking? Put a short code in the QR and validate it on your server — this tool only makes static codes. For links use URL QR.
FAQ
How long?
Technically kilobytes, but dense modules scan poorly. Stay near ~100 characters.
Unicode / Korean / emoji?
Yes — UTF-8. Non-ASCII costs more bytes, so the same character count can make a denser QR.
Coupon or one-time codes?
Yes. Short alphanumeric codes scan best. Use ECC Q+ and print ≥3 cm wide.
Is text uploaded?
No. Payload stays in the browser and only becomes QR pixels.
