자주 묻는 질문

›Is the QR code an image I can download?

Yes — download as PNG. You control the size, foreground/background colors, and error-correction level.

›Is there a character limit?

QR codes hold up to ~4,000 alphanumeric characters depending on error-correction level. Shorter inputs scan more reliably.

›What error-correction level should I pick?

L (7%) for short URLs in clean conditions. H (30%) for printed codes that might get damaged or have a logo overlaid.

›Can I add a logo?

Currently we generate clean codes. Download the PNG and overlay a logo with any image editor — error correction H tolerates that.

›Is the generator free?

Yes — fully free, no signup, no usage limits.
