CSS Minifier

Minify pasted CSS by removing comments and unnecessary whitespace.

Output
 

Shrink CSS for production

Minified CSS loads faster because every unnecessary space, line break, and comment is stripped. This minifier collapses pasted CSS to a compact form you can ship, without touching what the styles actually do.

It is handy for one-off files, inline critical CSS, and snippets that never pass through a build pipeline. Paste your stylesheet, get the minified version, and copy it — the smaller payload means a quicker download for every visitor.

Smaller CSS, kept local

Stripping whitespace and comments shrinks what the browser downloads without changing how it renders. Your CSS is minified in the browser and never uploaded.

Frequently asked questions

What does the CSS minifier remove?

Comments, line breaks, and spaces around braces, colons, semicolons, and commas.

Is this as good as a build tool?

It handles the basics. Build tools like cssnano also merge rules and shorten values, so they go further on large stylesheets.

Can minifying break my CSS?

Rarely, since it only removes whitespace and comments. Keep your original file for editing and test the minified version once.
