Micro QR generator
The miniature QR variant for tiny surfaces — a single position marker and very short content.
Screen settings
Colors apply to every export. The scan check re-decodes the recolored code, so a low-contrast combination fails honestly — dark bars on a light background scan best.
PNG/JPG export in high resolution, SVG for websites — and the PDF is true vector in RGB: sharp at any size, right for documents and office printers.
About Micro QR
Micro QR is the compact sibling of the QR code: one position marker instead of three and far less overhead, so it fits on component labels, jewelry tags and PCBs where a normal QR would not. The price is capacity — at most around 35 digits or 21 alphanumeric characters — and lower error correction.
Important caveat: many consumer phone cameras do not recognize Micro QR. Use it for industrial readers, and pick a regular QR code for anything consumers should scan.
Used for
- Electronics and PCB marking
- Tiny product labels (jewelry, tools)
- Industrial traceability with dedicated readers
Frequently asked questions
Why does my phone not read a Micro QR?
Many phone camera apps only support regular QR. Micro QR is aimed at industrial scanners — for consumer scanning, use a normal QR code.
Micro QR or DataMatrix for small surfaces?
DataMatrix usually wins: comparable size, higher capacity and much broader reader support, including EU pharma standards.
