Aztec Code Generator

Any text, including URLs, line breaks and accented characters, which are encoded as UTF-8. The largest symbol holds about 3800 digits, 3000 letters or 1900 bytes, and this tool accepts up to 3832 characters.

The tool uses the smallest symbol that fits your data, from the compact 15 by 15 module form up to the full 151 by 151 module form. Short texts produce compact symbols with a smaller bullseye.

The tool reserves about 23 percent of the symbol for Reed Solomon error correction, the level the Aztec standard recommends. A code with some damage, glare or dirt can therefore still be read.

No. Aztec codes are located through their central bullseye, so they do not need a quiet zone and can be printed close to other graphics. The tool still adds a small white margin so the code stands out on any page.

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. The scale accepts 1 to 10, and the image may be at most 4000 pixels on a side.

Railways and airlines print them on mobile and paper tickets, hospitals on patient wristbands, and several countries on vehicle registration documents. They are also used for payment and loyalty codes in mobile apps.

Most barcode scanner apps and ticket validation devices read Aztec codes, and some phone camera apps do as well. Test with the readers your users have before printing.

Aztec is a two dimensional matrix code with square modules and no human readable line, so only the format and the scale apply.

No. It is used only to draw the code you download.
