Frequently Asked Questions
How do I generate a secure WiFi QR code?
Select the "Wi-Fi" protocol, specify your Network SSID and security type (WPA/WPA2 is standard), and enter your password. Scanning this code on a mobile device initiates an automated secure connection handshake.
Can I add my logo without breaking the QR code?
Yes. Our generator automatically escalates the Error Correction Level (ECL) to "High" (30% recovery) when a logo is detected. This ensures that even with a central logo overlay, the data pattern remains 100% readable.
What is the best scale for high-quality printing?
For professional print materials (business cards, posters), we recommend the default 10x scale or higher. This ensures the output PNG has sufficient pixel density for high-DPI offset or digital printing.
