The short answer
HTML Lens Web is a free online HTML viewer that runs locally in your browser. The viewer itself does not upload your document. A document can still request its own remote fonts, images, scripts, or stylesheets if its code tells it to.

Paste your code or choose an HTML file from your device.
02
Render
HTML Lens displays it inside a sandboxed preview.

Common questions
Is the HTML viewer free?
Yes. Rendering, source viewing, and the browser-based local library are available without an account.
Does HTML Lens upload my HTML?
No. HTML Lens has no server receiving your document. If the HTML itself references third-party resources, the browser may request those resources directly.
Can I use it on an iPhone?
Yes, the web tool works in a mobile browser. The native iPhone app is designed to open local HTML files directly from Files, Mail, and the share sheet.
Can it run JavaScript?
Interactive HTML can run inside an isolated preview. It cannot read HTML Lens local storage or call the native bridge.
