About CSS Minifier
Minifying CSS reduces file size and speeds up page loads by removing comments, line breaks and the spaces around braces, colons and semicolons. This tool performs a safe, lightweight minification suitable for quick optimisation. For production builds, a full toolchain is still recommended, but this is perfect for snippets. It runs entirely in your browser.
FAQ
Does it change my styles?
No — it only removes comments and whitespace; the rules themselves are unchanged.
Is it safe for production?
It is a lightweight minifier ideal for snippets; use a full build tool for large codebases.
Does it remove the last semicolon?
Yes — redundant semicolons before a closing brace are removed.
