CSS Minifier

CSS Minifier reduces the file size of your CSS by removing unnecessary characters — whitespace, comments, redundant semicolons, and zero units. Smaller CSS means faster page loads and lower bandwidth usage.

How to Use

  1. Paste your CSS code into the input panel.
  2. Toggle Remove Comments to strip CSS comments.
  3. Toggle Remove Unit from Zero Values to strip units from 0 values.
  4. Click Transform to minify the CSS.
  5. Click Copy to copy the minified output.

How It Works

The minifier strips comments, collapses whitespace around braces/colons/semicolons, removes trailing semicolons in rule blocks, and optionally removes units from zero values (e.g., 0px → 0).
