CSS Minifier
Strip comments, whitespace and unnecessary characters from your CSS to reduce file size — all in your browser, nothing uploaded.
Why minify CSS?
Stylesheets often carry a lot of formatting meant purely for readability — comments, indentation, line breaks. None of that affects how your page looks, but all of it adds bytes the browser has to download before it can render your page.
Minifying removes that overhead safely, without changing any actual styling rules.
Frequently asked questions
Will minifying change how my site looks?
No — this only strips comments, whitespace and redundant characters. The actual CSS rules and their order are preserved exactly.
Should I edit the minified version directly?
Not recommended — keep your original, readable CSS as your working file, and use the minified output only for what you deploy live.
Is my code uploaded anywhere?
No — minification happens entirely in your browser. Nothing you paste here is sent to our servers.
