This tool removes safe whitespace from simple CSS examples or restores readable line breaks for inspection without sending the stylesheet to a server.
Designed for: Frontend developers and technical writers reviewing small stylesheet examples.
How to use this tool
Paste a small stylesheet and choose Minify or Format. Review comments, strings, custom properties, and generated output before using it in a build pipeline.
How the result is produced
The browser applies conservative token-aware replacements for whitespace around common punctuation and formats braces and semicolons. It is intentionally not a full CSS parser or optimizer.
Test examples
`.card { color: #333; margin: 0 1rem; }` can be made more compact while preserving the declaration text. A string containing spaces should not be treated as ordinary formatting whitespace.
Limitations
The tool does not resolve imports, optimize selectors, validate browser compatibility, rewrite source maps, or guarantee correctness for every CSS grammar feature. Use a real build tool for production assets.
Privacy and processing
The CSS stays in the browser and is not uploaded.
