HTML Beautifier and Minifier
HTML is the foundation of every web page. Keeping it clean and well-structured helps with readability, debugging, and maintainability. Minifying it before delivery reduces page weight and improves load time — particularly for server-rendered pages that are not already compressed.
When to beautify HTML
Template engines, CMS exports, and email builders often produce messy, compressed markup. Beautifying re-indents elements so nesting is easy to follow, making it straightforward to locate specific tags, audit accessibility attributes, or refactor structure.
When to minify HTML
HTML minification removes comments, collapses whitespace between tags, and strips optional attributes — all without changing how the page renders. Combined with gzip or Brotli compression at the server, minified HTML transfers significantly faster than formatted source.
Minification options
- Remove comments: Strips HTML comments from the output. Comments are invisible to users but add bytes to every response. Conditional comments used for legacy IE support are preserved.
- Collapse whitespace: Removes newlines and redundant spaces between tags. The visual result in the browser is identical because HTML ignores consecutive whitespace.
- Minify inline CSS: Applies CSS minification to the contents of style blocks and style attributes inside the HTML document.

Minification uses html-minifier-terser, an actively maintained fork of the original html-minifier. Beautification uses js-beautify. Both libraries run on the server — your markup is never stored.
