Why Privacy Matters: The Hidden Risks of Online QR Generators
Did you know that most free online QR generators are data harvesters? When you create a Wi-Fi QR code for your home or office, you are often sending your SSID and Password to a remote server. When you generate a crypto wallet address, that data is logged.
IonianCore is different. We have built a Zero-Knowledge Architecture. This tool runs 100% in your browser using local JavaScript libraries. Your sensitive data never leaves your device. Once you close this tab, the data is gone forever.

|---|---|---|
| Data Processing | In Browser (Secure) | Sent to Cloud |
| Wi-Fi Keys | Never Exposed | Stored in Logs |

Mastering the Tool: Advanced Features

- 📇 vCard QR Code Generator: We support full UTF-8 encoding. This means you can create digital business cards in Greek, Chinese, Arabic, or Hindi, and they will save correctly to phone contacts.
- ✨ Transparent Background: Ideal for designers who want to overlay the QR code onto posters or flyers without a white box background.
Technical Specifications for Professionals
Unlike basic generators, IonianCore offers professional-grade standards suitable for developers and designers:
- Error Correction Levels (ECC): Adjustable from L (7%) to H (30%). Use 'High' when embedding logos to prevent scanning errors.
- Output Formats: We provide Raster (PNG) for standard use. Vector (SVG) is available for high-precision scalability (Note: SVG output is disabled when a custom logo is added, as logos require raster processing).
- Zero-Knowledge Protocol: All computation happens in a dedicated Web Worker on your device (Client-Side). No API calls, no latency, no server logs.
Optimized for Accessibility & Performance
IonianCore prioritizes Web Accessibility (a11y). Our generator is navigable via keyboard, screen-reader friendly, and utilizes high-contrast colors by default. We ensure that creating digital tools doesn't leave anyone behind.
