- **Collapse Whitespace** (checkbox): Collapse consecutive whitespace characters into a single space
- **Remove Comments** (checkbox): Strip HTML comments (conditional comments are preserved)
- **Remove Redundant Attributes** (checkbox): Drop attributes that match their element defaults (e.g. type="text" on inputs)
- **Minify Inline CSS** (checkbox): Compress CSS inside tags and style="" attributes</x-turndown>
- **Minify Inline JavaScript** (checkbox): Compress JavaScript inside tags and event handlers</x-turndown>
- **Remove Optional Tags** (checkbox): Drop tags that browsers infer (e.g. closing , )

## When to use

- When optimizing inline styles and scripts embedded directly within your HTML documents.
- When cleaning up redundant attributes and comments generated by visual editors or CMS platforms.

## How it works

- Paste your raw HTML code into the input text area.
- Select your optimization preferences, such as collapsing whitespace, removing comments, or minifying inline CSS and JavaScript.
- Click the minify button to process the code and copy the compressed output instantly.
