StackQR lets you generate static QR codes directly in the browser without signing up or being tracked. Type a plain-English description — like 'wifi CaféNet password latte123' — and it instantly produces the right code type. Supports six formats: URL, WiFi, email, phone, SMS, and plain text. Download in PNG, SVG, JPEG, WebP, or GIF. Batch generation handles multiple codes at once, and inline editing lets you correct details without starting from scratch. Because the codes are static, they never expire and don't rely on any third-party redirect service staying online.
