Paste HTML or open an .html file to see its rendered output instantly.
Your rendered page will appear here.
External resources and scripts are off.
Paste a complete document or a small snippet to check the rendered result. The HTML code viewer is useful for reviewing saved examples, email markup, generated templates, and quick UI ideas. It is an HTML visualizer, not a validator — it renders the markup without checking whether it follows a standard.
Open an .html or .htm file up to 2 MB — an HTML file viewer and online HTML reader for pages you have saved or received. The file is read and rendered locally and is not uploaded to Phoenix Code. Relative files are not imported with it, while absolute images, styles, fonts, frames, and media load only when you enable external resources.
HTML and inline CSS work by default. External images, styles, fonts, frames, or media require their control. JavaScript becomes available only with external access because scripts can contact or navigate to other sites and may make the tab unresponsive. The HTML renderer uses a restricted iframe without same-origin access; forms, popups, preview downloads, and top-level navigation remain blocked.
Switch the viewport between Responsive, Desktop, Tablet, and Mobile presets, or enter a custom pixel width to see how a layout adapts. The tool also runs on phones, so it doubles as a mobile HTML viewer when you need to check a page away from your desk.
Paste HTML into the source panel. Live preview is on by default, so the rendered result updates after you pause typing. Turn live preview off if you prefer to use the Refresh preview button manually.
Yes. Choose Open .html file and select an .html or .htm file up to 2 MB. The HTML code reader works entirely in your browser; the file itself is not uploaded to Phoenix Code.
Inline CSS is enabled. External page resources are blocked until you select Allow external resources. To run JavaScript, enable external resources first; preview scripts can contact or navigate to other sites and may make the tab unresponsive. Only run code you trust.
A viewer is for quickly rendering a document or snippet. An editor supports longer authoring work such as managing project files, code hints, and synchronized preview. Phoenix Code provides HTML and CSS editing with Live Preview, while Phoenix Pro adds direct visual editing and richer device preview tools.
Yes. It is a free HTML viewer with no sign-up or install, and the only limits are the 2 MB file size and 2 million character caps. Because rendering happens locally, nothing is uploaded and it stays fast on slow connections.
Highlight Mode connects an element in Live Preview to its HTML source.
Move from a quick preview to writing and testing HTML code in a complete web project, without losing the connection between source and rendered page.
