Frequently Asked Questions

How do I create a QR code for free?
Use our free QR code generator: select your mode (URL, text, WiFi, or contact), enter your details, and click Generate. No signup or payment required.
What is a WiFi QR code?
A WiFi QR code lets others join your wireless network by scanning a code. Enter your SSID, password, and encryption type to generate one.
Can I create a QR code for my contact info?
Yes. Switch to Contact mode and enter a name, phone number, email, and organization. The tool generates a vCard 3.0 QR code that most phones can import directly.
Does the QR code expire?
No. Because QR codes are static images generated entirely in your browser, they do not expire and require no ongoing service.
What is the best size for a QR code?
We generate QR codes at 512 by 512 pixels. This size is large enough for print and screen use while remaining lightweight.
Can I scan QR codes without an app?
Yes. Both iOS Camera and most Android devices have native QR code scanning built in.
Is QR code generation safe?
Yes. All QR code generation happens locally in your browser. No data is uploaded to any server.
What is error correction level?
Error correction lets a QR code stay scannable even if part of it is damaged. We use High (H) error correction for better reliability.
Can I use QR codes for business cards?
Yes. Use the Contact mode to generate a vCard QR code. When scanned, it can add the person directly to a phone's contacts.
How do I download a QR code image?
After generating your QR code, click the Download PNG button to save the image to your device.
