Accepts .html, .htm

Rendered with Sandboxed iframe + Shiki. Nothing about this file is ever sent to a server — open your browser's Network tab while using this viewer and you'll see no request carrying your file's contents.

What you can do with this tool

  • Rendered view: see the page as laid out, with CSS and images
  • Source view with syntax highlighting for the raw markup
  • Embedded scripts are disabled for safety — this is a viewer, not a script runner
  • One-click toggle between rendered and source
  • Download the original file back at any time

Frequently asked questions

Will embedded JavaScript run?
No — scripts are disabled in the rendered view for safety. This is a viewer, not a sandboxed app runner.
Will external images or stylesheets load?
If the HTML file references external URLs (an <img> pointing to a website, for example), your browser will fetch those directly when rendering, the same as opening the file locally. The file itself is never uploaded anywhere — only resources it explicitly links to may load from their original source.
Can I see the raw HTML source?
Yes, switch to the Source view for syntax-highlighted markup.
Is my file uploaded anywhere?
No, it's rendered entirely in your browser.
Can I edit the HTML here?
This is a viewer, not an editor. For editing, use your usual code editor.
