Background

Data Matrix is a small square 2D code that fits a lot of information into very little space, which is why it is used on electronic parts, medicine packs, lab samples and shipping labels. Type the text, a serial number or a link and the code appears straight away, sized by the module width you choose. Phone cameras and industrial scanners read it, and every code is read back before you download it as PNG or SVG. Everything happens in your browser.

Questions

Data Matrix or QR code?

Both are square codes. Data Matrix stays readable at smaller sizes and is the standard on parts and medicines; QR codes are what most people's phones expect for links.

Can phones read Data Matrix?

Many phone scanner apps can, and Google Lens can. The built-in camera app on some phones reads only QR codes.

How big should I print it?

Keep the bars crisp and give them space: print at 100% (don't stretch it), leave a white margin around the code, and use dark bars on a light background.

Is anything uploaded?

No. The code is made in your browser, and what you type stays on your device.
