priv QR is a free QR code generation platform focused on practical, real-world applications. It provides browser-based tools to convert URLs or text into QR codes in STL format for 3D printing, generate and decode Matter setup codes for smart home devices, and create batches of QR images from CSV data. All QR payloads are generated locally in the user's browser without requiring an account or login. The platform includes guidance for printing scannable QR codes, with profiles for different use cases like product tags, event badges, wall signs, and engraved plates. Users can export files in STL, SVG, or PNG formats and test their QR codes before production.

Shopper questions

Is priv QR free and no sign-up?

Yes. Core priv QR tools are free to use and do not require an account, login, or sign-up. QR content is generated in the browser.

Can QR codes be 3D printed?

Yes. QR codes can be 3D printed when the small squares are large enough, the clear border is preserved, and the physical part has enough contrast for phone cameras.

What size should a 3D printed QR code be?

It depends on how much text the QR stores and how far away people scan it. Start around 65-80 mm for a general prototype, then increase width if the small-square warning appears.

Can I generate QR codes in bulk?

Yes. Upload 1–20 CSV rows to the Bulk QR generator. Choose PNG or SVG and download the generated files in a ZIP with a per-row results report. Processing stays in your browser.

What thickness works for an STL QR code?

A 2 mm backing with about 1-2 mm of raised height is a practical starting point for many prototypes. Material and finish can require more height.
