QR Batch Studio

Paste a list or open a CSV and get a print-ready PDF of QR code labels — exact millimetre sizes, a clear quiet zone around every code, and a scale bar to check your printer.

Stays on your device. QR codes and the PDF are generated in your browser, with no online QR service. Works offline after the first visit.
