About

priv QR is a free browser-based tool for creating QR codes, barcodes and Matter device setup codes designed to work in the physical world. Generate a single QR code as an STL file for 3D printing, create static QR codes without redirect links, decode Matter setup payloads, or batch-generate PNG and SVG files from a CSV upload. The tool also converts Code 128, EAN-13 and UPC-A barcodes to STL format, and creates Bitcoin, Ethereum and Lightning payment QR codes.

All QR payloads are assembled in your browser, so your content stays local and there are no redirect links or account requirements. You get immediate preview as you type, then download PNG, SVG or STL exports. The site includes practical print profiles for product tags, event badges and wall signs, with guidance on dimensions, materials and scan testing to help you verify codes work before printing batches.

No login needed to use the core generators. The tool flags dense QR content and checks square sizes to catch potential printing issues early. You can download sample STL files and matching SVG or PNG references to test the exact output in your intended environment before committing to a full print run.

priv QR focuses on QR codes that leave the screen and work in physical space. It generates STL files for 3D printing, includes Matter commissioning tools, provides batch CSV processing, and offers practical print profiles with scanability guidance rather than just basic QR generation.

Problem: Standard QR generators create codes for screens. When you need QR codes on printed products, 3D parts, badges or signage, you need different tools: STL exports for 3D printing, batch processing for multiple codes, and guidance on whether your code will actually scan after printing.
Solution: priv QR generates QR codes as STL files for 3D printing, creates Matter setup codes, batch-processes CSV files into PNG or SVG, and provides print profiles and scanability checks to ensure codes work in physical environments.
