Customizing, Styling & Downloading Your QR Code
Make your QR code match your brand colors, insert your shop logo in the center, and download high-resolution files ready for printing.
#Why Brand Customization Boosts Scan Rates by 35%
Standard black-and-white QR codes can look impersonal, utilitarian, and sometimes even suspicious to cautious customers. When your QR code proudly displays your brand palette and company logo in the center, it communicates authenticity and trust.
Studies show that customized, branded QR codes achieve up to 35% higher scan and conversion rates compared to generic default codes. With Karo Simple, you can customize colors, add your logo, and download high-resolution files in seconds without hiring an expensive graphic designer.
#Downloading Your QR Code: PNG vs SVG Formats
When your QR code is ready, click the "Download" button on the QR card. You will be prompted to select between two formats. Here is how to choose the right one:
- PNG (Raster Image): Best for standard desktop printing, digital flyers, email signatures, billing software, Word documents, and Canva designs. It downloads as a crisp high-resolution graphic that looks sharp at standard sizes.
- SVG (Vector Graphic): Best for professional print shops, sign makers, laser-engraved acrylic stands, and large banners. Vector graphics use mathematical lines instead of pixels, so they never blur, pixelate, or lose sharpness even if scaled to the size of a billboard.

#Changing Your QR Code Colors (Foreground & Background)
Match your QR code to your interior decor, brand guidelines, or marketing collateral:
Open the Color Palette Modal
Locate the QR code card you want to customize and click the "Colors" or paint palette icon button.
Select Your Foreground Color
The Foreground Color is the color of the QR code dots and corner eye patterns. Select one of our curated high-contrast presets or type in your exact brand HEX color code (e.g., #1E3A8A).
Select Your Background Color
The Background Color is the canvas behind the dots. White or very light off-white (#FFFFFF or #F8FAFC) is standard and recommended.
Save and Preview
Click "Save" or "Apply". The QR code preview will immediately update with your new colors.
Important Contrast Warning: Keep It Scannable!
Smartphone camera lenses rely on strong optical contrast between dark and light pixels. Always maintain a dark foreground on a light background. Never use light yellow or pale gray dots on a white background, or dark navy on black, as cameras will struggle to focus or fail to scan altogether under dim lighting.

#Adding Your Shop Logo to the Center of the QR Code
Putting your brand logo in the center of the QR code makes it immediately recognizable and professional. Karo Simple uses high-grade Reed-Solomon error correction, which ensures that even when 30% of the code area is covered by your logo, the remaining data redundancy guarantees flawless scanning on every device.
Click the "Logo" Button
On the QR code card, click the "Logo" or image upload icon button.
Upload a Crisp Square Logo
Select a JPG or PNG file from your computer or phone. For best results, use a clean square image with a transparent background or white border.
Automatic Centering and Halo Protection
Karo Simple automatically resizes your logo and adds a subtle protective white halo around it so it stands out cleanly against the QR dots.
Save and Test Scan
Click "Save". Always test your new QR code with your own phone camera to confirm it scans instantly before printing hundreds of copies.
#The Advanced Full-Screen QR Design Studio
