What does HTML minification do?
Minification removes unnecessary characters from HTML without changing what the browser renders: HTML comments, redundant whitespace between tags, and line breaks are all safe to remove. The result is a smaller file that loads faster over the network. Typical savings range from 10–30% depending on how much whitespace and comments the original file contained.
Frequently asked questions
Will minification break my HTML?
For standard HTML, no. This tool removes comments and collapses whitespace — operations browsers treat identically to the original. Whitespace inside pre, textarea, or script tags should be preserved; for production use, consider a dedicated build tool like html-minifier-terser which handles edge cases.
Why is my CSS/JS not minified?
This tool minifies HTML structure only. Inline CSS within style tags and JavaScript within script tags are not minified. Use a dedicated CSS or JS minifier for those.
