## What this tool does
Generate a crisp QR code for URLs, text, WiFi strings or vCards — PNG or SVG.

## Typical user problems
- Free QR sites watermark the result, expire the link after a scan quota, or route your URL through a redirect farm. Here the payload is encoded directly — it never expires and scans straight to your destination.

## Parameters
- text: string, required. 二维码内容. URL / 文本 / WiFi:... / BEGIN:VCARD...
- size: number (range 64-2048px), optional. 尺寸
- format: enum, optional. 格式

## Pricing
- Watermarked preview: free, no login required
- Final clean output: $0.99 one-time per task
- Require login (email/phone OTP) to complete payment
- Result available for download 24 hours after payment

## Limitations
- Plain payload only — no redirects, no analytics
- Up to ~2000 characters of payload
- Higher error correction fits dirtier surfaces; keep the quiet zone when printing
