CSS Formatter

Beautify or minify CSS stylesheets. Free, runs entirely in your browser — no signup, and nothing you paste in is uploaded.

Consistent formatting makes stylesheets diffable, which is the real win — a rule reformatted onto one line per declaration produces diffs that show the property that changed rather than the whole block. That difference compounds on every review of a shared stylesheet.

Minifying strips whitespace and comments and is what you ship. Worth knowing what it cannot do: it does not reorder or merge rules, because CSS is order-dependent and two rules of equal specificity are resolved by which came last. Anything claiming to shrink your stylesheet by rearranging it is making a much riskier promise.
