A live two-pane HTML editor
Markdown Monk's HTML editor puts a visual editor and the raw HTML source side by side. Whichever pane you change, the other updates instantly — so you can compose visually and still keep full control of the markup, or hand-edit the code and see the result render live.
Clean up messy HTML in one click
Content pasted from Word, Google Docs, or a CMS is usually buried in inline styles,
stray classes, empty tags, and comments. Tick the options you want and press
Clean HTML to strip the noise. You can remove inline styles, classes and IDs,
leftover attributes, <span> wrappers, empty tags, and comments — or
strip every tag down to plain text.
Write semantic, accessible markup
Enable semantic conversion to turn <b> into
<strong> and <i> into <em>,
and to unwrap deprecated tags like <font> and
<center>. The result is leaner, more accessible HTML that's easier
to style and maintain.
Frequently Asked Questions
How does the two-pane HTML editor work? +
The left pane is a visual (WYSIWYG) editor — type or paste rich text like a word processor. The right pane shows the underlying HTML source. Edit either side and the other updates in real time.
How do I clean messy HTML from Word or Google Docs? +
Paste your content into the visual editor, tick the clean-up options you want (remove inline styles, classes, IDs, empty tags, comments, and so on), then press “Clean HTML”. The tool strips the clutter and rewrites tidy HTML in both panes.
What does the semantic conversion option do? +
It replaces presentational tags with semantic equivalents — <b> becomes <strong>, <i> becomes <em> — and unwraps deprecated tags such as <font> and <center> for cleaner, more accessible markup.
Is my content uploaded anywhere? +
No. Everything runs entirely in your browser. Your HTML never leaves your device, so it is completely private.
