- Removes unnecessary line breaks, whitespaces and indentation characters
- Removes comments
- Removes the last semicolon of a style declaration and extra semicolons
- Removes empty CSS declarations
- Shortens zero values (e.g. -0px), removes units when using zero values
- Removes the leading 0 if a float value is lower than one
- Keeps a single charset per CSS file removing all extra declarations
- Chances RGB color values to a shorter hexadecimal format
- Shortens hexadecimal color codes, the pattern #AABBCC is reduced to #ABC
