Frequently Asked Questions

What does HTML minification do and why is it important?

HTML minification removes unnecessary characters from HTML code without changing functionality.

Will minifying HTML break my website or affect functionality?

No, proper HTML minification never breaks functionality.

How much file size reduction can I expect from minification?

File size reduction varies based on your HTML's original formatting. Well-formatted HTML with proper indentation typically sees 20-40% reduction.

Should I minify HTML comments and when should I keep them?

For production websites, you should almost always remove HTML comments because they add unnecessary file size, expose development notes to users, may contain sensitive information not meant for public viewing.

Can I use minified HTML with my CMS or website builder?

Yes, but the approach varies by platform. For WordPress, use minification plugins like WP Rocket or Autoptimize that automatically minify HTML on every page load. For static HTML sites, manually minify files before uploading to your server.
