# Css Minifier — REST API endpoint `css-minifier`

Minify CSS (strip comments and whitespace) or beautify compressed CSS, and return the output with byte sizes and the percentage saved. Minify removes comments, whitespace around punctuation, and the last semicolon in each block. Beautify puts one declaration per line with the chosen indentation.
