CSS Minifier
Minify CSS instantly. Remove comments, whitespace, and redundant syntax.
Why minify CSS? — Minified CSS loads faster, reducing Time to First Byte and improving Core Web Vitals. A typical stylesheet shrinks 20–40%.
Production workflow — Minify CSS as part of your build step (Vite, Webpack, Parcel) for automatic minification on every deploy. Use this tool for quick one-off minification or for CSS you can't run through a bundler.
Preserve comments with /*! — Some tools (not this one) preserve /*! … */ bang-comments for licenses. Strip those manually if you need to before pasting here.
Keyboard shortcut — Press Ctrl+Enter (or ⌘ Enter on Mac) while in the input to minify instantly.

Your code never leaves your device.
