# OnlyQR - SVG QR Code Generator

A simplified, SVG-only QR code generator based on QRCode.js. This lightweight library generates clean, scalable SVG QR.

Try it out at [OnlyQR Demo](https://onlyqr.0n8.de).

## Embedding via URL

Everything after the domain becomes the QR code content, and the page shows only the QR code, scaled to fit:

```html
<iframe src="https://onlyqr.0n8.de/hello-world" width="200" height="200" style="border:0"></iframe>
<iframe src="https://onlyqr.0n8.de/https%3A%2F%2Fexample.com?color=ff0000" width="200" height="200" style="border:0"></iframe>
```

- `?color=` takes a hex value without `#` (e.g. `ff0000`) or a CSS colour name. The default is `004c93`.
- Use `encodeURIComponent(text)` for the path, so that `?`, `#`, `%` and `/` in your text come through unchanged.
- Any other query parameters are treated as part of the text.
- This is handled by `404.html` on the static host, so it only works in iframes (not `<img src>`), and the HTTP status is 404.

## Changes from Original QRCode.js

- Removed Canvas and Table rendering methods
- SVG is now the default and only rendering method
- Simplified codebase with reduced file size
- Modern web interface included
- Automatic sizing based on QR code complexity
