Compress CSS stylesheets instantly to reduce file size and boost website loading speed.
What we do
Our tool instantly strips out unnecessary whitespace, spaces, tabs, line breaks, and CSS block comments (/* */) from your stylesheets to create a lightweight code block.
We integrated the industry-standard CodeMirror engine to provide real-time CSS syntax coloring and active highlighting, making it easier to review your raw code before compression.
Watch your savings in real-time. Our built-in Byte Calculator automatically compares your raw CSS file to the minified output and shows you exactly how much space you saved.
Don't want to copy and paste? Click the "Load .css" button to instantly upload entire stylesheet documents directly from your computer and compress them in milliseconds.
Because this minifier uses an advanced Client-Side regex engine, there are no loading screens or server wait times. The compression happens instantly right inside your browser.
Your proprietary styling code is completely safe. We never upload, store, or view your source code. The entire minification process runs securely on your local device.
