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 updates live, or switch to the Visual editor and format like a word processor while it writes clean, semantic HTML for you. Beautify re-indents messy markup, Minify strips whitespace for production, and Clean removes comments. 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

Visual editor

Write and format with a compact, Word-like toolbar - headings, bold, links, lists, quotes and tables - without touching a single tag.

Clean, semantic HTML

The visual editor emits W3C-valid markup: strong and em instead of b and i, real lists, links with a title, and blockquotes with a cite - no inline styles or junk classes.

SEO-ready elements

Insert accessible tables with header cells, ordered and unordered lists, headings and horizontal rules - the structure search engines and screen readers rely on.

Syntax-highlighted source

The code pane reads like a real editor, with line numbers and colour-coded tags, attributes and strings so mistakes are easy to spot.

Live preview

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

Beautify & minify

Re-indent tangled markup into clean nested code, or collapse whitespace to shrink the file - while preserving pre, textarea, script and style.

Clean

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

Tag balance check

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

Fully 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 There is no upload, no account and no server round-trip - safe for internal or unpublished pages.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

Switch to Visual to write and format like a document - the toolbar turns your text into clean, semantic HTML behind the scenes.
Or paste HTML into the Code pane; it is syntax-highlighted with line numbers, and the live preview renders it on the right.
Use Code, Split, Preview or Visual to focus on the view you need.
Click Beautify to format, Minify to compress, or Clean to strip comments and extra whitespace.
Copy the HTML or download it as index.html when you are happy with the result.

Common questions

Online HTML Editor FAQ

Does the Visual editor produce clean, SEO-friendly HTML?

Yes. The visual editor is built to emit semantic, W3C-valid markup: it uses strong and em rather than b and i, real ul, ol and li lists, headings, blockquotes with a cite attribute, links with a title, and accessible tables with header cells. It strips inline styles, editor classes and empty tags, so the code you copy is clean enough to publish.

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.

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.
