Why use an HTML viewer
An HTML viewer is useful when you need to preview HTML code without saving it into a file or switching to another app. You can paste markup into the page and see the rendered output immediately in the browser.
That makes this page useful for developers, editors, and content teams who search for HTML viewer, HTML previewer, or render HTML online and want a quick preview that stays focused on the code itself.
Preview HTML code online safely
Paste a full HTML document or a smaller fragment and the viewer will render it inside a sandboxed preview frame. That keeps the experience simple while avoiding the risk of running scripts from untrusted content.
It is a handy way to preview HTML online when you need to inspect headings, paragraphs, lists, links, inline styles, or layout snippets before you paste the code somewhere else.
Common HTML viewer use cases
Use this page to check copied HTML, review CMS snippets, preview template fragments, or confirm that markup looks correct before publication. It is also useful when you need a quick HTML previewer for examples, docs, or migration work.
Because the preview updates in the browser, the page is a practical answer for searches like HTML viewer online, preview HTML code, and render HTML snippet.
FAQ
What does an HTML viewer do?

Can I preview HTML code online?
Yes. You can paste HTML code online and see the rendered preview immediately inside the browser.
Does the HTML viewer allow scripts to run?
