よくある質問
Is the QR code saved or tracked?
No. The QR code is generated in your browser. Nothing is sent to a server or stored anywhere.
Can I encode plain text, not just URLs?
Yes. URLs, text, email addresses, phone numbers — any string can be encoded as a QR code.
Which formats are available?
PNG, JPG, SVG, and EPS. For print, SVG is recommended as it scales without quality loss.
Can I customize the design?
Yes. You can change colors, dot shape, and size to match your brand or print material.
What if the QR code is hard to scan?
Long text reduces scan reliability. Use a URL shortener, or increase the error correction level to H.
