Frequently Asked Questions
How to create a QR code online for free?
Simply enter your text, URL, or data in the input field, customize the appearance if desired, and click generate. Your QR code will be created instantly and can be downloaded as PNG or copied as SVG.
What can I encode in a QR code?
QR codes can contain URLs, plain text, contact information (vCard), WiFi credentials, email addresses, phone numbers, SMS messages, and more. The tool supports up to 2000+ characters depending on content type.
What is QR code error correction?
Error correction allows QR codes to remain scannable even when partially damaged or obscured. Higher levels (H) provide better damage resistance but create denser codes. Use High for physical printing and Low for digital displays.
Is this QR code generator secure and private?
Yes! All QR code generation happens entirely in your browser. Your data never leaves your device or gets sent to any servers. This ensures complete privacy and security for sensitive information.
What size should my QR code be for printing?
For print materials, use at least 512px or 1024px resolution. Ensure sufficient contrast and include adequate white space (margin) around the code. Test scan-ability at your intended print size before mass production.
Can I customize QR code colors?
Absolutely! You can customize both foreground (dark) and background (light) colors. Ensure sufficient contrast between colors for reliable scanning. Dark foreground on light background typically works best.
How to create a WiFi QR code?
Use the WiFi example format: WIFI:T:WPA;S:NetworkName;P:password;H:false;; Replace NetworkName and password with your actual WiFi credentials. Guests can scan to connect automatically without typing passwords.
What's the maximum data capacity of QR codes?
QR codes can store up to 4,296 alphanumeric characters, 7,089 numeric characters, or 2,953 bytes of binary data. However, smaller amounts create more scannable codes. Keep URLs short for best results.
