Frequently Asked Questions about QR Code Generator

What content types can I put in a QR code?

Our generator supports URLs (website links), plain text messages, and WiFi network credentials (network name, password, and encryption type). Each type has its own optimized input form.

Can I customize the colors of my QR code?

Yes! You can change both the foreground (code) and background colors using the built-in color pickers. This lets you match the QR code to your brand colors or design aesthetic.

What's the difference between PNG and SVG downloads?

PNG is a raster format ideal for digital use (websites, social media). SVG is a vector format that scales infinitely without losing quality, making it perfect for printing on business cards, posters, and packaging.

Can I use the QR codes commercially?

Absolutely. All QR codes generated with ZeroTools are yours to use for any purpose — personal, commercial, educational, or otherwise. There are no usage restrictions or attribution requirements.

How do I test my QR code before printing marketing materials?

Point your smartphone camera directly at your screen. If the URL banner or WiFi notification appears instantly, your QR code is ready for print.

What is the resolution of the downloaded PNG QR code?

PNG exports are rendered in crisp high resolution (256x256 up to 1024x1024 pixels), perfect for business cards and flyers.

Can I add a logo to the center of my QR Code without breaking it?

Yes. QR Codes use Reed-Solomon error correction, which allows up to 30% of the code area to be obscured. To add a logo: download your QR Code as SVG, open it in Figma or Illustrator, and overlay your logo centered in the middle. Keep the logo covering no more than 20-25% of the total area. Always test scannability with multiple smartphones before printing at scale.

What's the minimum size a QR Code should be for reliable scanning?

The minimum recommended size is 2cm × 2cm (about 0.8 × 0.8 inches) for close-range scanning. For larger materials, follow the 1:10 rule: the scanning distance should be no more than 10 times the QR Code size. A billboard viewed from 10 meters needs a 1-meter QR Code. Always leave a white quiet zone of at least 4 modules around the code border.
