How to use it

Online HTML Editor

What is an online HTML editor?

An online HTML editor lets you write or paste HTML and see it render instantly, without any software to install. Type in the code pane and the preview on the right updates live in a sandboxed frame. Beautify re-indents messy markup, Minify strips whitespace for production, and Clean removes comments and empty attributes. Copy or download the result as a ready-to-use index.html — everything runs in your browser, so nothing is uploaded.

Everything you can do here

boltLive preview

Edit and watch the rendered page update as you type, in an isolated sandbox that keeps your page and Novaverb separate.

format_align_leftBeautify

Re-indent tangled or minified HTML into clean, readable, nested markup with consistent two-space indentation.

compressMinify

Collapse whitespace and drop comments to shrink the file, while preserving the exact contents of pre, textarea, script and style.

cleaning_servicesClean

Remove HTML comments and collapse redundant whitespace to tidy up pasted or exported markup before you reuse it.

balanceTag balance check

The status bar flags when opening and closing tags do not match, so you catch a forgotten closing tag before you ship.

shield_lockFully private

Your HTML never leaves the browser. There is no upload, no account and no server round-trip — safe for internal or unpublished pages.

How to use the editor

Paste your HTML into the code pane, or click Sample to start from a working document.
Watch the live preview render on the right; switch Code, Split or Preview to focus on one pane.
Click Beautify to format, Minify to compress, or Clean to strip comments and extra whitespace.
Turn off Run scripts if you only want to preview the layout without executing JavaScript.
Copy the HTML or download it as index.html when you are happy with the result.

Common questions

Online HTML Editor FAQ

Does the preview run JavaScript and load external resources?

The preview renders inside a sandboxed iframe. JavaScript in your HTML runs when Run scripts is on, and external images, styles and scripts load from their real URLs. The sandbox isolates the preview so it cannot read or change the editor page around it.

Is my HTML uploaded or stored anywhere?

No. The editor, formatter and preview all run in your browser. Your markup is never sent to Novaverb or any server, so it is safe for private or unpublished pages.

What does Beautify do to my code?

Beautify re-indents the markup with two-space nesting so tags are easy to read. It preserves the exact contents of pre, textarea, script and style blocks and does not rewrite your attributes or change what the page renders.

Will Minify break my page?

Minify only removes whitespace between tags and drops HTML comments. It keeps the literal contents of pre, textarea, script and style intact, so the rendered result stays the same while the file gets smaller. Review the output before deploying, as any layout that depends on significant whitespace should be checked.

What does the Balanced indicator mean?

It compares opening and closing tags, ignoring void elements like img and br. When they do not match it shows how many tags are unclosed, which is a quick way to spot a missing closing tag. It is a helper, not a full HTML validator.

Is my data uploaded anywhere?

No. This generator runs fully client-side in your browser. Nothing you type is sent to a server, so it is safe to use on private content.

Is it really free?

Yes, with no account. A Novaverb workspace is only needed when you want to verify, monitor, and track these files on your live site over time.
