Tip: Ensure good contrast between colors for optimal scanning

🛡️ What is error correction and which level should I choose?

Error correction helps QR codes remain scannable even when damaged:

Level	Recovery	Best For
🟢 Low	~7%	Digital display, clean environments
🟡 Medium	~15%	General use, balanced option
🟠 Quartile	~25%	Printed materials, outdoor use
🔴 High	~30%	Industrial, harsh conditions

💾 What format are the downloaded QR codes?

QR codes are downloaded as PNG images, which provide the best quality and compatibility. PNG format supports transparency, maintains sharp edges, and works perfectly for both digital use and printing. The files are high-resolution and suitable for professional use.

📱 Why won't my QR code scan properly?

Common scanning issues and solutions:

Poor contrast: Use dark colors on light backgrounds
Too small: QR codes should be at least 2cm × 2cm when printed
Damaged code: Increase error correction level
Bad lighting: Ensure adequate lighting when scanning
Blurry image: Keep camera steady and in focus
Wrong distance: Hold phone 6-12 inches from code

⏳ Do QR codes expire or have usage limits?

QR codes themselves never expire - they're just images containing data. However, if your QR code contains a URL, that link might become inactive if the website is removed or changed. The QR codes you generate with our qrcode-generator have no usage limits or tracking.

🔒 Is my data safe when using this QRCode Generator?

Yes, your privacy is protected. Our qrcode-generator processes everything locally in your browser - your data never leaves your device. We don't store, track, or transmit any of the content you enter. The QR code generation happens entirely on your computer using JavaScript.
