==How It Works==

The magic of this converter happens in the browser, all thanks to a few powerful Web APIs. When you click the "Convert & Download as PNG" button:

* '''SVG to Image:''' The SVG code is read from the input field. It's then used to create a JavaScript `Blob`, which is then used as the source for an `Image` object. This effectively treats your SVG code as a complete image.
* '''Image to Canvas:''' The app uses a hidden `<canvas>` element. Once the `Image` object has fully loaded the SVG data, it is drawn onto this canvas.
* '''Canvas to PNG:''' The `canvas.toDataURL('image/png')` method is called. This is the key step that takes the content of the canvas and encodes it as a PNG image in a Base64-encoded string.
* '''Download:''' A temporary `<a>` link element is created programmatically. The PNG data URL is set as the link's `href`, and the `download` attribute is set to a filename (e.g., `ds-image.png`). Finally, the link is "clicked" to trigger the download, and then it's removed from the page.
