About priv QR
Our Mission
priv QR is a free, no-login QR product focused on codes that need to work after they leave the screen: QR Code to STL, 3D printed QR codes, Matter setup data, and practical generation tools.
The product is built around local browser processing where possible, clear export formats, and guidance that helps users verify QR codes before printing, mounting, onboarding, or sharing them.
🔒 Privacy First
All QR code generation happens entirely in your browser. Your sensitive data - cryptocurrency addresses, contact information, WiFi passwords - never touches our servers.
⚡ Lightning Fast
Generate QR codes in under 50ms with zero dependencies. Our optimized algorithms ensure instant results without compromise on quality.
📱 Works Offline
Once loaded, priv QR can keep core tools available without round-tripping sensitive QR content through a server.
🏗️ Professional Grade
Built for professionals with STL output, SVG and PNG references, bulk processing, validation reports, and practical scanability guidance.
What Makes Us Different

- Matter Device Setup - Onboarding QR data for commissioning and device pairing
- Cryptocurrency Payments - Bitcoin, Ethereum, and Lightning Network with full compliance to BIP-21, EIP-681, and BOLT-11 standards
- Bulk Processing - CSV-based batch generation for enterprise use cases
