What is a QR code, and what does it stand for?
QR stands for Quick Response. A quick response code is a two-dimensional matrix barcode capable of storing data. It was invented by the Japanese company Denso Wave originally for use in logistics in 1994.
Why do I need a QR code?

What kind of information does a QR code store?

What types of QR codes can I create?
StealthQR supports 10 content types: URLs, vCards (contact information), WhatsApp, files, locations, videos, plain text, WiFi credentials, social media profiles, and calendar events. Each type has its own specialized input form to make creation easy.
Is it possible to track QR code scans?
Because StealthQR prioritizes privacy with client-side static QR codes, we do not track your visitors or redirect through proxy servers. If you need scan tracking, you can encode a URL containing UTM campaign parameters or your own analytics tracking link.
Can I customize the appearance of my QR code?
Absolutely! You can choose from dot patterns, eye styles, custom brand gradients, background colors, and embed logos into the center of your QR codes.
What formats can I download my QR code in?
You can download your QR code in high-resolution PNG, SVG vector format (best for print and scalable signage), or JPEG. You can also copy the QR code directly to your clipboard.
Do QR codes expire?
Static QR codes generated by StealthQR never expire. The data is encoded directly into the matrix itself. As long as your destination link remains active, the QR code will scan indefinitely.
