Minifier for HTML, CSS and JavaScript

Comments, line breaks and spaces that aren’t needed, and in JavaScript also long local names and dead code. A small example, minified by this page’s CSS rules: "a { color : red ; margin: 0px 0.5em ; }" becomes "a{color:red;margin:0 .5em}".

Servers usually compress files with gzip or Brotli anyway, which removes much of what minifying would. Minifying still helps: the page shows both sizes so you can see the real saving for your file.

1. Paste the code (the language is detected).
2. Copy or download the minified result.
3. Test it before shipping, as with any build step.
