What a QR code can contain

A QR code stores text. That text can be a web address, email address, phone number, Wi-Fi configuration, contact card or plain note. The scanner decides how to interpret the content.

NoFussKit creates a static QR code, so the encoded content cannot be changed after download. Test the final file before printing or distributing it.

Size, margin and contrast

Larger output contains more pixels and is better for print, while the margin creates the quiet zone scanners need around the code. Do not crop this empty border away.

Use a dark foreground on a light background. Decorative low-contrast combinations may look attractive but reduce reliable scanning, especially on older phones or in poor light.

• Keep a clear margin
• Use strong contrast
• Avoid stretching after export
• Test on more than one phone

Error correction levels

Level L stores the most data with the least recovery. M is a balanced default. Q and H add more redundancy so a partly damaged code may still scan, but they produce a denser pattern.

Higher correction does not fix an invalid link. Open the encoded URL first and use HTTPS whenever possible.

PNG or SVG?

PNG is a fixed-size raster image that works well in documents and social posts. SVG is vector-based and can scale for signs or print without pixelation.

For professional printing, use SVG when the design software supports it. For everyday sharing, PNG is usually simpler. Both files are generated locally in the browser.
