CSS Minifier & Beautifier

CSS (Cascading Style Sheets) files can become large and unwieldy. Minifying them removes unnecessary characters like spaces, indentation, and comments, which significantly reduces file size and speeds up your website.

Why use this tool?

  • Better Performance: Smaller CSS files download faster, improving your Core Web Vitals score.
  • Readable Code: Use the 'Beautify' mode to unpack minified CSS from other sites so you can read and edit it.
  • Safety: We process your code in your browser. No files are uploaded to our servers.
