Frequently Asked Questions

Are QR codes generated with your tool free to use commercially?

Yes! All QR codes created with our generator are completely free to use for both personal and commercial purposes. There are no licensing fees, attribution requirements, or usage restrictions. Use them on products, marketing materials, websites, or anywhere else without any concerns.

What is the best size for a QR code?

For digital use (websites, emails), 256x256 or 300x300 pixels works well. For printing (business cards, flyers), use at least 512x512 pixels or higher. The minimum recommended physical print size is 2x2 cm (0.8x0.8 inches). Larger is generally better for scanning from a distance. Always test your printed QR code before mass production.

Do QR codes expire?

No, QR codes themselves never expire. However, if your QR code links to a URL, the link can become broken if the website goes down or the page is removed. For dynamic content, consider using a URL shortener with redirect capabilities so you can update the destination without changing the QR code.

Can I edit a QR code after creating it?

Once generated, a QR code cannot be edited - the encoded data is permanent. If you need to change the content, you must generate a new QR code. This is why dynamic QR codes (using URL redirects) are popular for changing campaigns - you keep the same code but redirect to different destinations.

What error correction level should I use?

Level L (Low - 7% recovery) is fine for digital use or controlled environments. Level M (Medium - 15% recovery) is good for most printed materials. Level Q (Quartile - 25% recovery) works for outdoor use or rough surfaces. Level H (High - 30% recovery) is best for critical applications or if the code may get damaged or dirty.

Can I change the colors of my QR code?

Yes! Our generator allows custom foreground and background colors. However, ensure high contrast between the two - dark foreground on light background works best. Avoid low-contrast combinations (like light gray on white) as they may not scan reliably. Always test your colored QR code before using it widely.

Is my data safe when using this QR generator?

Absolutely! Our QR code generator runs entirely in your browser using client-side JavaScript. No data is uploaded to our servers or transmitted anywhere. Your information stays on your device, ensuring complete privacy. You can verify this by checking your browser network tab - no uploads occur.
