How to Use:

Using the HTML Code Cleaner is straightforward. Start by choosing your preferred editing mode: Visual Editor for WYSIWYG editing or Code View for direct HTML editing. If you're cleaning Word content, use the Visual Editor and paste directly from Word using the paste button.

In the Visual Editor, you can format text, add headings, lists, and other elements using the toolbar. Switch to Code View to see the generated HTML code. Configure your cleaning options by checking or unchecking the cleaning options based on your needs. Click "Clean HTML" to process your code.

The cleaned HTML will appear in the output area with real-time statistics showing file size reduction, tag count, and other metrics. Review the cleaned code, then copy it to your clipboard or download it as an HTML file for use in your projects.

Use Cases & Examples:

Example 1: Cleaning Word HTML
When copying content from Microsoft Word to a website, Word adds hundreds of unnecessary tags and attributes. Use this tool to remove Word bloat, reducing file size by 50-70% while preserving content and basic formatting.

Example 2: Email Template Optimization
Clean HTML before creating email templates. Remove unnecessary attributes and format code for better email client compatibility. However, keep inline styles for email HTML as many clients strip external stylesheets.

Example 3: CMS Content Import
Before importing HTML into WordPress, Joomla, or Drupal, clean the code to remove Word-specific tags and attributes that can cause conflicts or display issues in the CMS.

Example 4: Code Formatting
Use the format option to pretty-print messy HTML code with proper indentation, making it easier to read, debug, and maintain during development.

Example 5: Production Optimization
Minify HTML code before deploying to production by removing unnecessary whitespace and comments, reducing file size and improving page load times.
