What this tool does

This tool tokenizes CSS-like text locally, strips comments and tightens common separators so a stylesheet becomes smaller while remaining readable to browsers.

How to use it

  1. Paste CSS into the input box.
  2. Review the compact output and size difference.
  3. Copy the minified CSS into your stylesheet or build notes.

Privacy

This tool runs entirely in your browser. Your input is never uploaded, stored or shared — closing the tab removes it.

Frequently asked questions

Is my CSS uploaded?
No. Minification runs entirely in the browser tab.
Does it perform advanced optimization?
No. It focuses on safe whitespace and comment removal, not selector merging or risky rewrites.
Can I use it for snippets?
Yes. It works well for small rules, embedded CSS and quick stylesheet cleanup.
