Micro QR Code Generator

Overview

Micro QR has one finder pattern instead of three and needs a margin of two modules instead of four, so it fits where a QR code does not. It holds up to 35 digits, 21 letters and digits in upper case or 15 bytes. Phone camera apps do not document reading Micro QR, so use it with scanners that support it; the editor shows which readers do, and decodes your code with ZXing-C++.

Electronic partsA part number on a circuit board or a small component.

How it works

Add your content

Pick what the code does: open a link, join Wi-Fi, save a contact, pay, and more. Fill in the fields.

Design it

Start from a preset, then change the module shape, the eyes, the colours, the logo and the frame. Edit single pixels if you want.

Check it

Every change is decoded under four conditions. If something hurts the scan, the check says what and fixes it in one click.

Download

PNG at the size you need, SVG, or a vector PDF at your print width.

Frequently asked

Can my phone scan a Micro QR code?

Do not count on it. Apple's Camera app documentation mentions only QR codes, and Google's ML Kit lists QR Code but not this type. Use a scanner or an app that supports Micro QR.

How much fits?

Up to 35 digits, 21 upper-case letters and digits, or 15 bytes in the largest size, M4, at level L. Upper case fits more than lower case, because it uses the alphanumeric mode.

Can I style it?

Colours, module shapes and the frame, yes. The finder ring has to stay square, because Micro QR readers depend on it; the editor only offers the shapes that read.
