CSS Minifier & Beautifier

Minify CSS to reduce file size or beautify it for readability. Pure browser-based processing.

This css minifier and beautifier handles both directions of CSS formatting from a single input box. Minify mode strips out comments, collapses redundant whitespace, removes unnecessary spacing around punctuation like braces and colons, trims trailing semicolons, and drops units from zero values — all common wins for cutting stylesheet size before deployment. Beautify mode reverses the process, taking compressed or poorly formatted CSS and reflowing it into properly indented rules with each declaration and selector on its own line, which makes third-party or minified CSS easier to read and debug. A live stats bar shows the exact size before and after, plus the percentage saved when minifying. It's a handy stopgap for developers who want quick results without wiring up a full build tool or bundler, and everything runs locally in the browser.
