What data formats can this QR generator encode?

URL/text, WiFi credentials (WPA/WEP), email (MATMSG format), and vCard contact information.

Are my QR codes stored on ScanSuite servers?

No. All generation and rendering happens locally in your browser. Nothing is uploaded or stored.

What is QR code error correction?

Error correction adds redundant data so scanners can read partially damaged or obscured codes. Levels range from L (7%) to H (30%).

Can I customize QR code colors?

Yes. Set custom foreground and background colors. Ensure high contrast for reliable scanning.

What file formats can I download?

PNG for raster images and SVG for scalable vector graphics suitable for print production.

How do WiFi QR codes work?

They encode SSID, password, and encryption type in a standard WIFI: URI format that iOS and Android recognize automatically.

What is a vCard QR code?

A QR code containing contact information (name, phone, email, organization) in vCard format that phones can save directly to contacts.

What is the maximum data capacity?

QR codes support up to ~4,296 alphanumeric characters at error correction level L, though shorter payloads scan more reliably.

Static QR codes encode fixed data permanently. The encoded URL or content remains valid as long as the destination exists.

Can I add a logo to my QR code?

This tool does not overlay logos. Use error correction level H if you plan to add a logo in external design software.

Why is my QR code so dense?

Long URLs or large data payloads require more modules. Consider using a URL shortener to reduce code density.

What size should I print QR codes?

Minimum 2cm x 2cm for close-range scanning. Larger codes scan from farther distances. Test before mass printing.

Are QR codes free to use commercially?

Yes. The QR code format is an open ISO/IEC 18004 standard with no licensing fees for generation or scanning.

What is the quiet zone margin?

The blank border around a QR code required for scanner detection. ISO recommends at least 4 modules of padding.

Can Android and iOS scan the same QR code?

Yes. Standard QR codes generated here are compatible with all modern smartphone camera apps on both platforms.

What encryption types does WiFi QR support?

WPA, WPA2, WEP, and open networks (no password) are supported in the WiFi QR format.

Is this QR code generator free?

Yes. ScanSuite provides unlimited free QR code generation without registration, watermarks, or daily limits.

How do I test my QR code before printing?

Use the live preview and scan it with your phone camera. Test on both iOS and Android devices for compatibility.
