TESTED & REVIEWED
WHY USE IT
Remove common editing residue while preserving scripts, styles, data attributes, accessibility attributes and page content.
The cleaned result is formatted with consistent indentation so it remains easy to edit.
Cleanup happens locally in your browser and your pasted markup is never submitted to our server.
HOW IT WORKS
Add source copied from an editor, CMS, email or existing webpage.
Comments, editing artifacts and unnecessary empty attributes are removed.
Check the formatted output, then copy or download cleaned.html.
CLEAN PASTED HTML SAFELY
Use HTML from a page editor, WordPress, a CMS, an email draft or an AI-generated component. A complete document and a small fragment are both supported.
Scripts, styles, data attributes and ARIA attributes remain in place. The tool does not pretend that every class, ID or inline style is unnecessary.
Compare the cleaned markup, preview it in the HTML viewer and run the HTML validator when broken nesting or invalid syntax may be part of the problem.
