Data Matrix is a very compact 2D code that stores many characters in just a few millimeters – the standard for industry, electronics and pharma serialization.
Its strong error correction makes it robust against scratches and partial occlusion, which is why it is often laser-etched directly onto parts.

How to create a Data Matrix code
- The type “Data Matrix code” is preselected – you can change it anytime in the generator.
- Enter your value (example: HELLO-123).
- Adjust colors, module size and the quiet zone and check the live preview.
- Download the Data Matrix code as PNG, SVG or PDF, or print an A4 label sheet.
Use cases
- Industrial marking
- Pharma and medical devices
- Small parts and components
Tips for clean printing & scanning
- Keep contrast (dark modules on a light background) and test with several camera apps.
- Leave a quiet zone all around – at least four modules for QR codes.
- On small surfaces prefer 2D codes: they store more data in less space.
