# QRCodeGen.ai

> Free online QR code generator. Create custom QR codes with colors, logos, and unique shapes — 100% browser-based, private, and instant.

QRCodeGen.ai is a browser-based QR code generator that processes everything entirely on the client side using JavaScript. No data is ever sent to a server, ensuring complete privacy — especially important when encoding WiFi passwords, contact details, or sensitive URLs.

## Supported QR Code Types

- **vCard** — Share contact information instantly: name, phone, email, organization, and more.
- **Email** — Pre-fill an email with recipient address, subject line, and body text.
- **Phone** — Dial a phone number with one scan.
- **SMS** — Pre-compose a text message with recipient number and message content.

## Customization Options

## Privacy

QRCodeGen.ai runs entirely in the browser. When you enter data (URLs, WiFi passwords, contact info), it is processed by JavaScript on your device. No network requests are made with your data. You can verify this by checking your browser's Network tab during use.

This is particularly important for:
- WiFi passwords (sent in plaintext in QR codes)
- Personal contact information (vCard)
- Private or internal URLs
