# QR Code Generator

> Generate QR codes from any text or URL — live preview as you type, download as PNG or SVG. No signup, no watermarks.

## What does this tool do?

The QR Code Generator creates QR codes from any text input. As you type, the QR code updates in real-time. You can customize the size and error correction level, then download the result as a PNG image or SVG vector file.

## What can I encode in a QR code?

Any text, including:
- **URLs** — e.g. `https://example.com/page`
- **Plain text** — e.g. `Meet me at 3pm`
- **Wi-Fi credentials** — e.g. `WIFI:T:WPA;S:MyNetwork;P:MyPassword;;`
- **Email addresses** — e.g. `mailto:hello@example.com`
- **Phone numbers** — e.g. `tel:+15551234567`
- **SMS** — e.g. `smsto:+15551234567:Hello there`
- **vCard contact info** — full vCard format
- **Geographic coordinates** — e.g. `geo:37.7749,-122.4194`

## What customization options are available?

- **Size** — control the pixel dimensions of the output QR code
- **Error correction level** — four levels:
  - L (Low) — 7% of data can be restored if damaged
  - M (Medium) — 15% can be restored (default, good balance)
  - Q (Quartile) — 25% can be restored
  - H (High) — 30% can be restored (use when adding a logo overlay)

## What output formats are available?

- **PNG** — raster image, good for embedding in documents, emails, and web pages
- **SVG** — vector format, scales to any size without pixelation, ideal for print

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

Use this format in the input field:
