Style a QR code to match your brand
A plain black-and-white QR code works, but a custom one looks intentional. This maker lets you set the foreground and background colours, the output size in pixels, the quiet-zone margin, the error-correction level, and an optional centre logo — so the code matches your poster, deck, or packaging.
The content is still encoded directly into the pattern, so your custom code is static and never expires. Download a PNG at any pixel size, or an SVG vector that stays razor-sharp on a large print.
How to make a custom QR code
- Enter your content. Choose a content type and type your link or details.
- Choose your colours. Set the foreground and background in the Style section. Keep good contrast.
- Set size and margin. Pick the output size in pixels and the quiet-zone width.
- Add a logo and download. Optionally drop in a logo, then download as PNG or SVG.
Contrast is what makes it scan
Dark foreground on a light background is the most reliable combination. Avoid light-on-dark or low-contrast colour pairs, and never invert the colours (a light code on a dark background) unless you have tested it on several phones.
什么能让一个有样式的二维码保持可扫描
你可以自由地为二维码重新着色和调整大小,但 ISO/IEC 18004 标准中的几条物理规则决定了相机是否仍能锁定它:
| 设置 | 保持其可读的规则 |
|---|---|
| 对比度 | 在浅色背景上保持深色前景。低对比度的搭配以及浅色在深色上(反相)的代码在许多相机上都会失败。 |
| 静区 | 标准要求每一侧至少有 4 个模块的空白边距,以便相机能判断代码在哪里结束。 |
| 尺寸 | 对于打印,一个粗略的规则是扫描距离约为代码宽度的 10 倍——一个 2 厘米的代码在约 20 厘米处可读。更大更安全。 |
| 矢量(SVG) | SVG 在任何尺寸下都保持极其锐利,因此它是大型海报、横幅或包装最安全的导出格式。 |
颜色与尺寸提示
- 如果你想要彩色代码,请更改前景(深色模块)并保持背景为浅色,而不是反过来——相机预期深色在浅色上。
- 边距滑块设置静区;把它保持在约 4 与规范一致,是打印最可靠的选择。
- 不要缩小复杂的代码(长 URL 会形成更密集的网格);要么让内容简短,要么印得更大,以便单个模块保持清晰。
- 屏幕上或快速使用时导出 PNG,需要大幅打印时导出 SVG,然后在发布之前用手机扫描测试最终成品。

常见问题
Can I change the QR code colours?
Yes. Set any foreground and background colour in the Style section. Keep a strong contrast so cameras can read it.
What size should I make my QR code?
Choose a size that suits where it will appear. For print, bigger is safer — and an SVG download scales to any size without blurring.
Is a custom code still static?
Yes. Styling only changes the look; the content is still baked into the pattern, so the code never expires.
Where is my image processed?
Building or reading a QR code happens in your browser, so the file is created on your own device. How any data associated with the tool is handled is described in our privacy policy.
