Pixel-perfect styling

Pure black, white, or any hex. Transparent backgrounds. Rounded modules, classic squares. Your brand, your way.

Custom logo, clean

Upload a PNG or pull from a URL. We carve a clean clear-zone, strip dark backings, and keep ERROR_CORRECT_H scanability.

Multiple data types

URL, vCard, Wi-Fi join, mailto, SMS, geo, plain text. The API formats it correctly so every scanner offers the right action.

Print-ready output

Up to 4500×4500 px PNG (15″ at 300 DPI), or scalable SVG that prints at any size. Stickers, posters, t-shirts, billboards.

Production-grade

API keys, monthly quotas, 24-hour render cache, SSRF protection on logo URLs, atomic usage counters, audit log on every call.

One simple endpoint

POST /api/v1/generate/ takes JSON, returns image bytes. No SDK lock-in, no webhooks to wire.
