FAQ
- What optimizations are applied?
- Comments are removed, whitespace and newlines are collapsed, redundant semicolons and zero units are stripped, and color values are shortened where possible. The full clean-css level 2 optimizations are used.
- Will my CSS still work the same?
- clean-css is battle-tested and preserves semantics — strings, data URIs, and url() values are left intact. For production use, always verify the output visually.
- Is my CSS uploaded anywhere?
- No. All minification happens locally in your browser.
