Frequently Asked Questions
đ§ Getting Started

Is QR Master free to use?

đą QR Code Types
What types of QR codes can I create?
You can create QR codes for text, URLs, files, contact information (vCard), WiFi networks, phone numbers, email addresses, and more. Each type is optimized for the best scanning experience.
Can I create QR codes for files?
Yes! Upload your file (up to 10MB) and we'll create a shareable link that can be scanned to access the file. Supports images, documents, PDFs, and other file types.
How do WiFi QR codes work?
WiFi QR codes contain your network credentials. When scanned, devices can automatically connect to your WiFi network without manually entering the password.
đˇ Scanning
How do I scan a QR code?
Go to the Scanner tab, click 'Start Scanning', allow camera access, and point your device at the QR code. Our scanner automatically detects and formats different QR code types.
Why won't my QR code scan?
Ensure good lighting, hold your device steady, and make sure the QR code is clearly visible. Try adjusting the distance or cleaning your camera lens.
âī¸ Technical
What's the difference between error correction levels?
Higher error correction levels make QR codes more reliable but also more complex. Low (7%) is good for clean environments, while High (30%) works better when codes might be damaged or partially obscured.
What size should I use for printing?
For business cards, use 256x256 or higher. For posters or signs, use 512x512. Larger sizes ensure better scanning from various distances.
Is my data stored on your servers?
No, all QR code generation happens in your browser. Your data is stored locally on your device and never sent to our servers, ensuring complete privacy.
đ Privacy & Security
Are QR codes secure?
QR codes themselves are just data containers. Always verify the source before scanning unknown QR codes, especially those linking to websites or downloads.
Can I delete my history?
Yes, you can clear your generation and scan history at any time from the History tab. This data is stored locally on your device only.
