What is a QR code generator
A QR code encodes a URL, text or structured payload into a scannable pattern. This tool makes static codes — content lives inside the pattern itself, no redirect service, no expiry, no tracking.
如何使用
- 输入内容（网址、文本，或用模板生成 Wi-Fi / 名片格式）。
- 调整尺寸、容错等级与前后景色。
- 下载 PNG 或 SVG；要加 Logo 请选 H 容错。
FAQ
Do these QR codes expire?
No. The content is encoded directly into the pattern (a static QR) — it never expires and has no redirect dependency.
Can I use brand colors?
Yes — foreground and background are customizable. Keep dark-on-light high contrast; scanners depend on it.
Which error-correction level?
H survives ~30% occlusion — use it when embedding a logo. M is fine (and holds more data) otherwise.
Which format for print?
Choose SVG (infinitely scalable) or a large PNG; keep the printed code at least 2 cm across.
