CSS and JavaScript Minifier: Ship Less Code, Load Faster
Minification strips whitespace, comments, and redundant syntax from CSS and JavaScript without changing behavior. A 150 KB stylesheet might become 90 KB — saving transfer time, parse time, and memory on every page load.
This tool minifies directly in your browser. No build system, no npm install, no server upload.
Privacy
All parsing and minification execute entirely in your browser. Your source code never leaves your device.
