CSS minifier & beautifier

Paste your CSS, then minify it to the smallest size or beautify it into clean, readable formatting. See exactly how many bytes you save, then copy the result. Everything runs in your browser.

How it works

STEP 1

Paste your CSS

Drop in a stylesheet or a single rule. It is parsed right in your browser — nothing leaves your device.

STEP 2

Minify or beautify

Minify strips comments and whitespace and tightens punctuation for the smallest file. Beautify lays it out with one declaration per line and clean indentation.

STEP 3

Copy or download

Copy the result with one click, or download it as a .css file — and see how many bytes minifying saved.
