How it works and help

A little help along the way

Follow these steps. Every option is explained underneath, and nothing you type leaves your device.

  1. Say what it should openWebsite (a page, a menu, a form), Wi-Fi, Contact or Text. An email, a phone number, a text message, an event, a place, a social profile, a payment or a barcode is under More kinds. Fill in its fields; the code is drawn as you type.
  2. See that it scansEach code is read back on your device, three times: as made, small and a little out of focus, and in poor light. The page says It scans only when every reading is exactly what you typed, and what the code does in words. Details shows each reading and exactly what is in the code.
  3. Make it yoursPress Design it for the whole window: a ready-made style, colours and gradients, and the shapes of the modules and the three eyes. Anything that would make it harder to scan is said, with a button that fixes it.
  4. Add your logo and a frameChoose a logo (PNG, JPEG, WebP, GIF or SVG) or a plain mark. Room is made for it in the middle, and the code is made as large and as strong as it needs. Add a frame with words such as Scan me.
  5. Say how it will be usedOn a screen, Printed (4 cm wide) or Poster or sign (15 cm wide). Under More options, set any size in pixels, millimetres or inches at a number of dots to the inch, the error correction and the margin. The help says how far away a printed code scans from.
  6. Download itPNG for documents and slides; SVG, PDF or EPS for print and design programs, sharp at any size, with CMYK values for your printer if you like. Or copy it. Scan the printed code with your phone before you print many.

Questions people ask

What is a Data Matrix code for?
Much data in a small square: parts marking, electronics, medicines and labels. It still reads with part of it damaged.
Can it make PDF417 and Aztec codes too?
Yes, and MicroPDF417, Micro QR, rMQR and MaxiCode: choose them on the same page.
Is the code read back?
Yes, with zxing-cpp, and compared with what you typed before it says it scans.
