Preguntas frecuentes
Are these static or dynamic QR codes?
Static. The content is encoded directly into the QR code and never changes — no redirect, no tracking and no account. Dynamic QR codes (editable destination, scan analytics) need a redirect service, which this tool does not offer, by design, for privacy.
Is my data uploaded?
No. Everything is generated entirely in your browser — your content is never uploaded, stored or logged.
Is my image uploaded?
No. Decoding happens entirely in your browser with a local library; the image is never uploaded, stored or logged.
Why can't it read my image?
Decoding needs a reasonably clear, well-lit QR with good contrast. Very blurry, low-contrast, angled or partial codes may not decode — try a sharper image.
Is it really free?
Yes — free, with no signup, no watermark and no limits.
