FAQ

Frequently asked questions

What is an HTML previewer?

An HTML previewer renders HTML code in the browser so you can see the page output instead of only reading source code.

Can I preview HTML with CSS and JavaScript?

Yes. Paste HTML that includes CSS or JavaScript and ViewHTML renders it in the live preview.

Can I share the HTML preview?

Yes. Use Link or QR Code to create a shareable preview after the rendered result looks right.

Is this like CodePen or JSFiddle?

ViewHTML is simpler. It is focused on fast HTML preview, sharing, and export rather than full project editing.
