Question 1

What is an HTML viewer?

Accepted Answer

An HTML viewer is an online tool that renders your HTML code and shows you exactly how it looks in a browser, without needing to create a file or open a separate browser tab.

Question 2

How do I preview HTML online?

Accepted Answer

Paste your HTML into the input panel and click Preview (or press Cmd+Enter / Ctrl+Enter). The tool instantly renders your HTML in a live preview panel.

Question 3

Does it support HTML snippets?

Accepted Answer

Yes. Paste any HTML fragment — with or without DOCTYPE — and the viewer renders it immediately.

Question 4

Is my data safe?

Yes. Use the Mobile (375px), Tablet (768px) and Desktop buttons to simulate different screen widths in the preview panel.

Question 6

Can I open the preview in a new tab?

Accepted Answer

Yes. Click the Open button to open your rendered HTML in a full browser tab.
