Domande frequenti
›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.
