Printed in the file with the barcode, outside the quiet zone, in Helvetica or Courier so it looks the same in every format.

Bar width reduction0 mil

Makes each bar thinner by this amount, to make up for ink that spreads on paper. Ask your printer for the value, or leave 0 for laser and thermal printing.

Rotation and backgroundNew0° · Filled

Rotation

In the preview, a checkered pattern shows the transparent areas. Print a transparent barcode only on a white or very light surface: scanners need the light quiet zone around it.

Margin and borderNew0 mm · no border

The margin is blank space outside the quiet zone, for cutting; the border is drawn at the outer edge. Both count in the print size.

      How to Generate a Micro QR Code

      Type short data, choose the version and error correction if you need to, and download the file.

      1. Type the data: digits fit best, then capital letters and digits.
      2. Keep Smallest that fits, or choose M1 to M4.
      3. Choose error correction L, M or Q; Q needs version M4.
      4. Download SVG, PNG, PDF or EPS and scan a test print with the scanner you will use.

      Micro QR Versions M1 to M4

      Micro QR has four versions, from 11 × 11 to 17 × 17 modules, and each one limits the data it can hold.

      Sizes and Data

      • M1: 11 × 11 modules; digits only, with error correction L.

        Micro QR code version M1, 11 × 11 modules, holding the digits 12345.

      • M2: 13 × 13 modules; digits, capital letters, space and $ % * + - . / :.

        Micro QR code version M2, 13 × 13 modules, holding BC-2026.

      • M3: 15 × 15 modules; any data.

        Micro QR code version M3, 15 × 15 modules, holding the text Part 42 with a lowercase letter.

      • M4: 17 × 17 modules; any data, up to 35 digits or 21 capital letters and digits.

        Micro QR code version M4, 17 × 17 modules, holding BARCODE.CODES.

      Error Correction Levels

      • L: low, available in every version.
      • M: medium, from M2.
      • Q: quartile, only in M4.

      Micro QR Code Specifications

      These are the rules of Micro QR Code as described in the encoder's reference, which cites ISO/IEC 18004.

      Micro QR Code vs QR Code

      Micro QR is a smaller variant of QR Code for very small spaces and short data.

      When to Choose Micro QR

      Choose Micro QR when the space is very small and the data is short, such as a part number. For web addresses and anything longer, use QR Code.

      Scanning Micro QR Codes

      Check that the scanner or app you rely on reads Micro QR before printing, because support varies between readers.

      Testing Your Code

      Print a test copy at the final size and scan it with the device that will be used. The Barcode.codes scanner and image reader read Micro QR in the browser.

      Frequently Asked Questions

      Is This Micro QR Code Generator Free?

      Yes. There is no account, watermark or download limit, and the codes may be used commercially.

      How Much Data Fits in a Micro QR Code?

      Up to 35 digits or 21 capital letters and digits in version M4 with error correction L. Other text fits fewer characters; the capacity line shows the limit for your data.

      Why Does M1 Reject My Letters?

      Version M1 holds digits only, and M2 holds digits, capital letters and a few symbols. Choose M3 or M4, or keep Smallest that fits.

      What Is the Smallest Micro QR Code?

      Version M1, with 11 × 11 modules plus a quiet zone. Its printed size depends on the X-dimension you set.

      Can I Put a Web Address in a Micro QR Code?

      Only a very short one: lowercase letters and symbols fit few characters. A QR Code is the better choice for web addresses.

      Does Every Phone Read Micro QR Codes?

      Not necessarily: support depends on the scanning app. Test with the devices your readers will use.
