Micro QR Code Generator

At most 35 digits, 21 uppercase letters and digits, or about 15 bytes of other text in the largest version, M4. This tool accepts up to 35 characters and refuses data that does not fit.

A Micro QR code has one finder pattern instead of three, is 11 to 17 modules wide and needs a margin of only 2 modules. It holds far less data than a QR code but takes a fraction of the space.

The tool chooses the smallest of the versions M1 to M4 that can hold your data. Digits only produce the smallest codes, and lowercase letters or symbols need the byte mode and a larger version.

Usually not. Most phone camera apps read only regular QR codes. Micro QR is designed for industrial readers and dedicated scanner apps, so test with the reader that will be used.

Yes. Choose SVG for a vector file that stays sharp at any size in print and design software, or PNG for a raster image that works in documents, web pages and label printers. Both come with a white background and a white margin.

Each module is drawn 2 pixels per scale step, so at the default scale 3 a module is 6 pixels wide and an M1 code is 66 pixels before the margin. The scale accepts 1 to 10.

Only a very short one, because the byte capacity is about 15 characters. For website links use a regular QR code, which holds much more.

Micro QR is a square matrix code with no human readable line, so the format and the scale are the only settings.

It marks printed circuit boards, electronic components, small medical items and other parts too small for a full QR code, often printed or laser engraved at a few millimeters.

No. The text is used only to draw the code you download.
