CSS Minifier

Why Minify CSS?

Every unnecessary byte in your stylesheet slows page rendering. Minifying CSS removes comments, collapses whitespace, and strips redundant semicolons — often reducing file size by 30–60 %. The result loads faster, scores better on Lighthouse, and costs less bandwidth.

Features

  • Comment removal — strips all /* … */ block comments.
  • Whitespace collapse — collapses multiple spaces, tabs, and newlines into one.
  • Semicolon cleanup — removes trailing semicolons before closing braces.
  • Size comparison — see original vs minified byte count and savings percentage.
  • Copy to clipboard — grab the minified output with one click.

Common Use Cases

  • Preparing stylesheets for production deployment.
  • Reducing payload size for inline <style> blocks in emails.
  • Optimising critical CSS for above-the-fold rendering.
  • Shrinking third-party CSS before embedding in a bundle.
