What is an HTML Cleaner?

The HTML Cleaner is a powerful online tool designed to help developers and content creators clean, format, and minify HTML code directly in the browser. Whether you need to remove unnecessary tags, strip inline styles, or simply beautify messy code, this tool does it all instantly.

Secure and Private

Designed with privacy in mind, this tool processes your HTML code entirely on your device using JavaScript. No data is ever sent to our servers, making it safe for sensitive or proprietary code.

Key Features

  • Deep Cleaning: Remove empty tags, comments, and specific attributes like inline styles, classes, and IDs.
  • Security: Strip potentially dangerous elements like <script> tags and event handlers (e.g., onclick).
  • Formatting & Minification: Beautify your code with proper indentation or minify it to reduce file size.
  • Live Preview: See exactly how your cleaned HTML renders in a secure, sandboxed iframe.

How to Use

Paste your HTML into the editor, select your desired cleaning options from the panel, and click "Clean HTML". You can then toggle between the code view and the live preview, and download the result as an .html file.
