About this tool
CSS Minifier is a free, browser-based tool that lets you minify CSS by removing whitespace, comments, and redundant rules. It supports CSS → Minified. Everything runs locally on your device, so your files are never uploaded to a server. There's no sign-up, no watermark, and no limit — just open CSS Minifier, add your input, and get results instantly.

Enter raw CSS into the textarea.
See original size, minified size, and percentage saved live.
Click copy to save the compressed CSS.
Shrink CSS files for faster rendering.
No software installation required. Everything runs locally.
No hidden limits or premium paywalls.
CSS Minifier processes your data locally in the browser. Nothing is uploaded, tracked, or stored — your files never leave your device.

Preview snippets instantly, debug them with a console, test responsive layouts, and understand why a sandboxed preview matters when you paste code from the internet.
