QR Shuttle

A small web app to generate custom QR codes. Everything runs in the browser; no data is sent to any server, no watermarks.

• Quick templates – one-click starting points for the most common uses
• Full customization – foreground/background colors, size, error-correction level (L/M/Q/H), frame style, transparent background
• Logo embedding – place your logo in the center with automatic excavation
• Live preview – the code re-renders as you type and tweak
• Export – download as PNG, SVG, or JPG
• Bilingual – English and Chinese UI
