Frequently Asked Questions

What is HTML Preview?

HTML Preview is a browser-based live HTML editor that displays your code output in real time. You write or paste HTML on the left, and the rendered result appears instantly on the right β€” no setup or server required.

Does the preview support CSS and JavaScript?

Yes, the preview runs inside a sandboxed iframe that fully supports inline CSS styles and JavaScript. You can include <style> and <script> tags in your HTML and they will execute in the preview panel.

What does the auto-refresh toggle do?

When auto-refresh is enabled, the preview updates automatically as you type with a 300ms debounce to avoid excessive re-renders. If you turn it off, the preview stays static until you manually refresh or toggle it back on.

Is my HTML code sent to any server?

No. All code editing and preview rendering happens entirely in your browser. Your HTML is never uploaded or transmitted to any server, so your work remains completely private and secure.

Can I use this tool on mobile devices?

Yes. On smaller screens the editor and preview stack vertically for comfortable use. The tool is fully responsive and works on smartphones, tablets, and desktops alike.
