Free QR Code Generator

A QR (Quick Response) code is a two-dimensional barcode that can store various types of information like URLs, text, contact details, or other data. When scanned with a smartphone camera or QR code reader app, it instantly decodes the information and takes the appropriate action, such as opening a website or displaying text. QR codes use error correction algorithms, allowing them to be read even if partially damaged or obscured.

The error correction level determines how much of the QR code can be damaged while still being readable. Low (7%) is best for clean environments and creates smaller codes. Medium (15%) is the standard choice for most use cases. Quartile (25%) is good for outdoor use or printed materials that may get worn. High (30%) is ideal for industrial applications or when the code might be partially covered. Higher levels create more complex codes but offer better reliability.

Yes! Our QR code generator allows you to fully customize both the foreground (typically black) and background (typically white) colors. You can use any hex color code to match your brand identity or design requirements. However, ensure sufficient contrast between the foreground and background colors for optimal scanning reliability. Dark colors on light backgrounds work best.

PNG is a raster image format that's perfect for digital use, social media, and websites. It has a fixed resolution and file size. SVG is a vector format that can be scaled to any size without losing quality, making it ideal for print materials, large banners, or when you need flexibility. SVG files are also typically smaller in file size and can be edited in design software like Adobe Illustrator or Inkscape.

QR codes can technically store up to several thousand characters, but practical limits depend on the error correction level and scanning conditions. For URLs, we recommend keeping them under 300 characters for best scanning performance. Longer content creates more complex QR codes with smaller modules, which may be harder to scan, especially at smaller print sizes. For optimal results, use URL shorteners for long web addresses.

Yes, absolutely! All QR codes generated by our free QR code generator are completely free to use for any purpose, including commercial applications. You own the QR codes you create and can use them in marketing materials, product packaging, business cards, websites, or any other commercial or personal projects without any attribution or licensing requirements. The QR code technology itself is an open standard.
