Make your own QR codes in colour and in bulk with the QR Stuff QR code generator. High resolution artwork images, t-shirts, stickers and business cards too.

QR Code generation from
At QR Stuff we give you the opportunity to generate QR Codes in ways that most of the other places on the internet overlook.
Not everyone is happy with just being able to create a puny little GIF file that's only good for pinning to a web page, so we've extended the possibilities to include handy ways to get your QR Code out into the "real world" where it can actually work for you:
Generate QR Codes in printable formats – either a single code or as an array of codes – and then you print them out yourself.
Generate a QR Code and then email it to someone.
Generate QR Codes that are good enough to use as artwork for a t-shirt and allow you to actually buy the shirt with your custom QR Code on it via the Zazzle print-on-demand website.
Generate unlimited numbers of high resolution QR Code artwork files for graphic design use at up to 25.4cm (10 inches) at 300dpi by opening a subscription account. More info about subscriptions here.
About Our QR Codes
We don't use the Google Charts API for QR Code generation – we use a custom ISO-compliant alogorithm – so we aren't bound by the image size and resolution limits imposed by other sites that have the Google generator as their back-end.
The specifications for our generated QR Codes are:
Content dependent automatic array sizing between 21×21 modules (Version 1) and 117×117 modules (Version 25). Please Note: 33×33 modules (Version 4) is the usual maximum workable limit of camera phone based scanning systems.
Maximum theoretical data capacity for alphanumeric data encoding of 1853 characters
"Quiet Zone" border width of 4 modules or 4% of symbol width, whichever is greater
Shortened URL encoding for web site addresses based on the domain.
SMS encoding limited to messages of <140 characters.
Support for L and M level Reed-Solomon error correction.
JIS X 0510 and ISO/IEC 18004:2006 compliant
VCARD 2.0 and VACAL 2.0 compliant
FNC1 indicators in accordance with the UCC/EAN Application Identifiers data format requirements where applicable
Symbol rotation and structured append not supported

A QR Code (it stands for "Quick Response") is a mobile phone readable barcode that's been big in Japan forever, broke into Europe a while back, and is now getting traction in USA.

In its simplest sense think "print based hypertext link" – simply encode a URL into the QR Code and then point a mobile phone (or other camera-enabled mobile) at it. If the device has had QR Code decoding software installed on it, it will fire up its browser and go straight to that URL.

But it doesn't stop there – a QR Code can also contain a phone number, an SMS message, V-Card data or just plain alphanumeric text, and the scanning device will respond by opening up the correct application to handle the encoded data appropriately courtesy of the FNC1 Application Identifiers that are embedded in the encoded data.

The technical specifications for a QR Code are set down in the ISO-18004 standard so they are the same all over the world, and the only significant variations from one QR code to another (apart from the data it contains) is the number of modules required to store the data. A Version 1 QR Code is a 21×21 array of data elements with the array increasing in size by 4 modules for each increase in version number. The largest standard QR Code is a Version 40 symbol that 177×177 modules in size and can hold up 4296 characters of alphanumeric data (theoretically) compared to 25 characters for a Version 1 QR Code.

While there is still a lot of scope for improvement, the resolution of average present-day camera-enabled portable devices is such that the size of the data modules (dots) on a QR Code of Version 5 or above (37×37) presents a real risk of incorrect decoding of the symbol by the device. When creating a QR Code intended for use with mobile phones and PDA's it's best to stick to Version 4 or lower, and a QR Code symbol of at least 2cm (0.85inches) across.

To make things a bit more robust, the QR Code also contains its own error correction data, internal orientation calibration and self-alignment markers. In this way it doesn't matter whether the QR code is upside down or wrapped around a curved surface, the message will still get through.
