Frequently Asked Questions

What is the main benefit of a live SVG editor?

The primary benefit is speed and immediate feedback. You instantly see the visual effect of every code change, making it much faster to debug errors, fine-tune design parameters, and learn SVG syntax than using traditional save-and-reload file-based editors.

Does the tool validate the SVG code?

Yes! The tool uses the browser's native DOM parser to validate SVG structure in real-time. If the code has XML syntax errors or invalid SVG elements, it displays a descriptive error message in the preview panel with the line number where the error occurred.

Is the image processed on your server?

No, this is a completely client-side tool. All editing, rendering, and processing happens directly in your web browser using JavaScript. Your SVG code is never transmitted to our servers or stored anywhere outside your device.

What browsers are supported?

The editor works on all modern browsers including Chrome 90+, Firefox 88+, Safari 14+, and Edge 90+. For optimal performance and feature support, we recommend using the latest browser version.

Can I import SVG files to edit?

Yes! You can drag and drop SVG files directly into the editor panel, or use the 'Open File' button to browse and select files from your computer. The content will load instantly into the editor.

Does it support SVG animations?

Yes! The editor fully supports SMIL animations, CSS animations within SVG, and animated SVG elements. You'll see animations play in real-time in the preview panel.

What's the maximum SVG file size I can edit?

The editor can handle SVG files up to 10MB. For very large or complex SVGs with thousands of paths, rendering may slow down depending on your device's processing power.

Are there keyboard shortcuts available?

Yes! Common shortcuts include: Ctrl+S (download SVG), Ctrl+Z (undo), Ctrl+Y (redo), Ctrl+F (find), Ctrl+/ (comment/uncomment), and Tab (indent). A full list is available in the help menu.
