About This Tool
The HTML Minifier removes whitespace, line breaks, comments, and other unnecessary characters from HTML source code to reduce file size and improve page loading speed.
Minified HTML renders identically to the original in browsers. Whitespace inside inline scripts and styles is also handled safely.
How to Use
  1. Paste your HTML code into the input area.
  2. Click the "Minify" button.
  3. Review the minified output.
  4. Click "Copy" to copy the result to clipboard.
Use Cases
Use for web page performance optimization, reducing server response size, deploying static HTML files, and pre-upload optimization for CDN.
FAQ
  • Can minification break my HTML? — It works safely for typical HTML. However, test separately for content inside pre tags or inline scripts sensitive to whitespace.
  • How much can minification reduce file size? — Depending on coding style, you can typically expect a 5–30% reduction in size.
  • Should I also minify CSS and JavaScript? — Yes, for better performance also minify CSS and JavaScript separately using the cssMinifier and jsMinifier tools.
  • Is there a way to automatically minify on the server? — Build tools like webpack, vite, and gulp can automatically minify HTML during the build process.
