priv QR

priv QR offers free QR tools that run in your browser, with no account or sign-up. The QR Code to STL Generator turns a URL or text into a raised QR model for 3D printing, with STL, SVG and PNG downloads and printer-aware presets for raised or recessed models. The Matter QR tool creates a Matter setup QR code or decodes an MT: payload locally. There is also a private static QR code generator with no redirect service and no imposed expiry, a bulk generator that turns 1–20 CSV rows into PNG or SVG files in a ZIP, a barcode to STL converter (Code 128, EAN-13, UPC-A) and a crypto payment QR generator (Bitcoin, Ethereum, Lightning). Guides cover QR print size, emboss vs engrave and why printed codes fail. Available in 7 languages.
