What makes qrdock different

Letter forge — type up to 4 letters and they appear inside the QR pattern, formed by the modules themselves. Fully scannable, verified live by a real decoder.
Private by architecture — every code is generated in your browser. Links, Wi-Fi passwords and UPI IDs never touch the server.
Actually free — no watermarks, no expiring codes, free SVG/PNG/JPEG/WebP up to 4096 px.
Every content type — URL, text, Wi-Fi, vCard, email, SMS, WhatsApp, UPI payment, location, calendar event + 6 barcode formats.
Dynamic QR codes — free accounts get short links with editable destinations and scan analytics (by day, country, device).
Scannability guardrails — contrast checking, logo damage budget, and a live decode badge on every edit.
