About the HTML Viewer
This tool lets you paste or type HTML and see the rendered result in real time. The preview updates as you edit. You can switch between light and dark mode to check how your content looks in both themes. All processing happens in your browser—nothing is sent to a server.
This free HTML viewer is part of our developer tools. Scripts in your HTML do not run in the preview for security; use it to preview structure and styling.
