QR Code Generator FAQ
Can I create a Wi-Fi QR code?
Yes. Select Wi-Fi, enter the network name, password, security type, and hidden network setting, then download the QR code.
Should I use PNG or SVG?
Use PNG for websites, chats, and quick sharing. Use SVG for print, design tools, and large-format assets.
How do I make a QR code easier to scan?
Use high contrast colors, keep a clear quiet zone margin, avoid tiny printed sizes, and test the QR code before publishing.
Do generated QR codes expire?
The static QR codes generated here do not expire. A QR code can stop working if its encoded destination, such as a webpage, is removed or changed.
Can I customize QR code colors?
Yes. You can choose foreground and background colors, but strong contrast should be maintained for reliable scanning.
