Two ways in
Paste code or upload an HTML file
Paste your code
Drop a full HTML document (markup, inline CSS, even scripts) into the editor and the preview updates live as you type. Great for quick edits and tweaks.
Upload a file
Drag and drop an .html file, or click to browse and pick one from your machine. It’s read straight into the editor in your browser. The file never leaves your device to render the preview.

HTML viewer FAQ
You already have one open: this page. Paste code into the editor above, or switch to Upload file and drop an .html file, and it renders in the preview next to it. On your own computer, any web browser is an HTML viewer too: drag the file onto a browser window, or right-click it and choose Open with.
It depends which view you want. To see what the code produces, paste it into the editor above and the rendered page appears in the preview. To see the code behind a page that is already online, open it in your browser and choose View Page Source (Ctrl+U on Windows, Cmd+Option+U on a Mac), then paste that source here to render and edit it.
For a quick look, a browser-based viewer like this one: nothing to install, live updates as you type, scripts run in a sandbox, and a mobile toggle to check small screens. For a project with many files, a code editor with a live preview (VS Code with its Live Preview extension, for example) suits better. And when someone else needs to see the page, no viewer helps: publish it as a link instead.
An HTML viewer is a tool that renders HTML markup into the page it describes, so you see headings, colors and buttons instead of tags. Every web browser is one. An online HTML viewer adds an editor beside the preview, so you can paste code, change it, and watch the result update.
Yes. The HTML viewer is completely free: paste or upload as much HTML as you like, no signup and no limits.
No. The preview runs entirely in your browser inside a sandboxed iframe. Nothing you paste or upload is sent to or stored on a server.
You don’t need to save the file and double-click it, and you don’t need a local server or an editor. Drag and drop the .html file (or paste the code) into the viewer above and it renders right here in a sandboxed frame, so you see the page without leaving this tab.
Open this page on your phone, tap “Upload file,” and pick the .html file from your downloads, and the preview renders directly in your mobile browser. On desktop, use the Mobile toggle above the preview to check how the page looks at phone width before you share it.
Yes. When the page looks right, publish it as a link: a clean URL you can send to a client instead of an attachment. Published without an account it stays live for 7 days; sign up free to keep it. A published page is public to anyone with the link and noindex. Phishing and pages built to collect other people’s passwords or card details are taken down.
Not when you publish it with Pagelive. Published pages are noindex by default: the robots meta and X-Robots-Tag headers tell search engines not to list it, unlike the easy free way most hosts work.
