Are QR codes generated here free to use commercially?

Yes. QR codes you generate here are completely free to use for personal or commercial purposes—print on products, business cards, menus, signs, or anywhere else. There is no expiry date and no registration required.

QR codes generated by this tool are static—they contain the data directly in the code and never expire. The URL or text is encoded in the QR pattern itself, not stored on a server.

What size QR code should I use for printing?

For printing, use at least 300×300px for small print like business cards. For posters or signs viewed from a distance, use 1000×1000px or larger. The minimum printable size for reliable scanning is about 2cm × 2cm (0.8 × 0.8 inches).

Can I track how many times my QR code is scanned?

Static QR codes (like this tool generates) cannot be tracked. For tracking, you need a dynamic QR code service (like QR Tiger or Bitly) that redirects through a tracking URL. Consider using a URL shortener with analytics as an intermediate step.

How much data can a QR code hold?

Standard QR codes can hold up to 7,089 numeric characters, 4,296 alphanumeric characters, or 2,953 binary bytes. For URLs and text, keep content as short as possible—complex QR codes (more data) are harder to scan from lower quality cameras.

QR (Quick Response) codes were invented by Denso Wave in Japan in 1994 for automotive manufacturing, but have since become ubiquitous in daily life. Modern smartphones scan QR codes natively through the camera app without any additional software. This makes QR codes the perfect bridge between printed materials and online content—scan once to instantly open a website, connect to WiFi, or save contact information.

QR Code Error Correction

QR codes support four error correction levels (L, M, Q, H) that allow the code to be read even when partially damaged or obscured. Higher levels (Q, H) allow 25-30% damage tolerance but produce denser, more complex codes. For printed materials that might get dirty, use M or Q level. For digital-only use, L level creates smaller, simpler codes.

Frequently Asked Questions

How long do QR codes last?

QR codes themselves don't expire—the code pattern is permanent once created. However, if your QR code links to a website that goes offline or changes URLs, the code will become non-functional. For long-term printed materials, consider using a URL shortener that lets you update the destination without reprinting the QR code.

What's the minimum print size for QR codes?

The minimum recommended print size is 2×2 cm (about 0.8 inches) for codes scanned from normal distances (under 20 cm). For codes viewed from farther away, scale proportionally. Always test scan your printed QR code before large print runs.

Can I add a logo to the QR code?

Our generator creates standard QR codes without embedded logos. You can add a logo over the center using image editing software—QR codes with up to 30% of the center covered (H-level error correction) can still be scanned successfully.
