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, so smart home makers can check and reproduce the setup codes printed on their devices without sending anything to a server.

There is also a private static QR code generator with no redirect service and no imposed expiry, so the code you print today keeps pointing exactly where you told it to. A bulk generator turns one to twenty CSV rows into PNG or SVG files in a ZIP, which is handy for labelling a batch of parts, shelves or devices. A barcode to STL converter supports Code 128, EAN-13 and UPC-A, and a crypto payment QR generator covers Bitcoin, Ethereum and Lightning.

QR content is processed in your browser, and all core tools are free and need no account. The batch limits of one to twenty CSV rows are performance limits, not paid tiers, and no paid plan exists on the site.
