QR Code Customizer
The same QR code with your own colours, module size and quiet zone, as a downloadable SVG.

What this tool does
The code itself is fixed by the standard, but how it is drawn is not: the two colours, how many pixels each module takes, and how wide the border around it is. Those three decide whether a code works on a poster, a business card or a screen. The output is an SVG, so it stays sharp at any size — printing a bitmap QR too large is one of the commonest reasons a code will not scan.

Frequently asked questions
Why is there a white border I cannot remove?
You can set it to zero, but you should not. That border is the quiet zone, and the standard requires four modules of it on every side. A scanner uses it to find where the code begins; without it, a code printed against a busy background or a dark colour can simply fail to be seen. The other thing that matters is contrast: dark on light, with a real difference between them. A light code on a dark background is read by some scanners and not by others.
