What is JSX?
**JSX (JavaScript XML)** is the syntax extension used by React to describe UI components. While it looks like HTML, it requires a transformation process to be rendered by a browser or converted into a static image. Our tool handles this transformation, allowing you to bridge the gap between dynamic code and static **PNG exports**.
// Sample React SVG Component
const Icon = () => (<svg width="40">
<circle fill="currentColor" />
</svg>
);
Pro-Tips for Perfect Rendering
Optimize your JSX for the sharpest image output.
Define a ViewBox
Always use 'viewBox' instead of just 'width/height'. This ensures your component scales perfectly during the JSX to PNG conversion.
Inline Your Styles
For complex gradients or unique colors, use inline style objects. This is the most reliable way to preserve visual fidelity.
Transparency Control
If you need a transparent background, ensure you export as PNG or WebP. JPEG will always default to a white background.
Font Consistency
Standard system fonts render best. If using custom fonts, ensure they are loaded in your current browser session.
JSX vs. SVG vs. Raster
| Feature | JSX / SVG | PNG | WebP |
|---|---|---|---|
| Scalability | Infinite (Vector) | Fixed (Pixels) | Fixed (Pixels) |
| Transparency | Supported | Supported | Supported |
| Use Case | Development | Documentation | Modern Web |
Where to Use Your UI Snippets
Troubleshooting
Missing Elements?
If parts of your SVG aren't appearing, avoid using 'foreignObject'. These require specific browser permissions that standard canvas rendering may block for security.
Blurry Exports?
Ensure the 'viewBox' matches the dimensions you are targeting. For high-DPI screens, our tool automatically optimizes the export quality.
