About CSS Minifier

Strips comments and whitespace, drops the last semicolon in each block, removes empty rules, shortens #aabbcc to #abc and 0.5 to .5.

It deliberately leaves alone the changes that break stylesheets: spaces inside calc(), the space before ( in media queries, 0px to 0, and anything inside strings or url(). Licence comments marked /*! */ can be kept.

How to use it

  1. 1Type or paste your text, or open a file.
  2. 2Choose any options - the result updates as you type.
  3. 3Copy the result or download it as a file.
