Frequently Asked Questions
How do I create a QR code for a website?
Select "URL / Link", paste your website URL, choose size and click Generate. Download the PNG and use it anywhere — on business cards, posters, or digital materials.
How do I create a WiFi QR code?
Select "WiFi", enter your network name (SSID), password, and security type, then click Generate. Anyone who scans this QR code will be able to connect to your WiFi automatically.
What is error correction level?
Error correction allows QR codes to be read even if partially damaged. Higher levels (H) allow up to 30% of the code to be damaged and still scan, but create denser, more complex QR codes. Medium (M) is the best balance for most uses.
Can I use custom colors for my QR code?
Yes! Choose any dark and light color combination. Ensure sufficient contrast between the two colors (dark on light) for reliable scanning. Avoid very similar colors.
What size QR code do I need?
For digital use: 256px is fine. For print: use 400–512px or larger. The minimum physical size for a scannable QR code is about 2×2 cm when printed.
