How do I create a Wi-Fi QR code for guests?

Click the 'Wi-Fi Network' tab, enter your network name (SSID), choose your security type (WPA/WPA2), and enter the password. When guests scan the generated QR code with their phone camera, they connect instantly without manually typing passwords.

How to create a direct WhatsApp chat QR code?

Select the 'WhatsApp' tab, enter your mobile phone number with your country code (e.g. 91 for India), and optionally type a default message. Scanning this QR code opens a direct conversation with your number on WhatsApp.

Frequently Asked Questions

Are these QR codes completely free and permanent?

Yes. Every QR code created with NexifyLabs is 100% static, free, and permanent. We do not insert redirects, watermark our branding, or charge monthly subscriptions after a certain scan count.

What resolution should I choose for print banners or flyers?

For physical business flyers, restaurant tables, or banners, select 1024 × 1024 px (Print HD) with Error Correction Level "M" or "Q". This ensures sharp scanning even from a distance.

Is my Wi-Fi password stored anywhere when creating a Wi-Fi QR?

No. NexifyLabs runs entirely client-side using JavaScript. Your network SSID and password are encoded directly into the QR image in your device's memory and are never transmitted over the internet.
