Frequently Asked Questions

What does HTML minification do?

HTML minification removes unnecessary characters like comments, extra whitespace, and line breaks without affecting how the page renders. This reduces file size and can improve page load speed.

Will minification break my HTML?

For standard HTML, minification is safe. However, whitespace inside <pre> or <textarea> tags is preserved. Always test your page after minifying.

Does it minify inline CSS and JavaScript?

Basic inline styles are preserved. Inline <script> and <style> blocks have their internal whitespace reduced.

Is my HTML sent to a server?

No. Minification is done entirely in your browser using JavaScript regex operations. Your code never leaves your device.
