How to customize QR code colors, dot shapes, eye patterns, and gradients while maintaining scannability. Create branded QR codes that match your design.
Our generator offers several ways to customize your QR codes:
Foreground & background
Square, rounded, dots, diamond
Corner finder styles
Linear & radial gradients
The most important rule for QR code customization is maintaining sufficient contrast. Poor contrast is the #1 reason custom QR codes fail to scan.
Dark foreground on light background
High contrast (70%+ difference)
Solid, saturated colors
White or very light backgrounds
Light foreground on dark background
Low contrast (similar brightness)
Very light or pastel colors for dots
Dark or busy pattern backgrounds
Before customizing, create your QR code with the content you want. Select your type (URL, WiFi, vCard, etc.) and enter the information. The customization options will be applied to this content.
Tip: Get the content right first - customization changes don't affect the encoded data.
Click on the "Style" tab in the generator. This reveals all customization options including colors, shapes, gradient settings, and logo upload.
Tip: The preview updates in real-time as you make changes.
Click on the foreground color picker to change the color of the QR code dots and patterns. Then set the background color. The default is black on white, which provides maximum contrast.
Tip: Click anywhere on the color picker, or enter a specific hex code for exact brand colors.
Choose how the main body modules (dots) of your QR code look. Options include: Square (classic, reliable), Rounded (softer, modern), Dots (circular, stylish), Diamond (unique, edgy).
Tip: Square is most reliable for scanning. Fancy shapes work better at larger sizes.
The three corner squares (called "eyes" or "finder patterns") can be customized separately. Change the outer frame shape and the inner eye shape independently for a unique look.
Tip: Eyes are critical for scanning - keep them clearly defined even with custom colors.
Enable the gradient toggle to apply a color gradient to your QR code. Choose two colors and select linear or radial gradient type. For linear gradients, you can adjust the angle.
Tip: Gradients look great but ensure both colors contrast well with the background.
After making changes, always scan the preview QR code with your phone. Verify it still scans quickly and reliably. If it's slow to scan or doesn't work, reduce customization complexity.
Tip: Test in different lighting conditions if the QR will be used in various environments.
Once you're happy with the design and it scans reliably, download in your preferred format. SVG maintains quality at any size, which is great for preserving custom designs.
Tip: Save your customization settings by creating an account and saving as a project.
