Minify CSS by removing comments, whitespace, and extra separators.
About this css minifier
Minify CSS snippets for demos, embeds, quick experiments, and small static projects directly in the browser.
Mavis Tools is built for quick utility work: paste the input, get the result, and move on. The page is static-first for speed, and the interactive work happens in your browser. That makes it useful for drafts, calculations, debugging snippets, and repeat everyday tasks.
This tool is intentionally focused. It does one job clearly instead of asking for an account or hiding the result behind a long workflow. Bookmark it if you need a fast css minifier that works on desktop and mobile.
FAQ

No. It is a lightweight minifier for common CSS snippets.
Does it upload code?
Yes. The tool runs in your browser, and the input is not uploaded to a server.
Can it remove comments?
Yes. Block comments are removed before whitespace is compacted.
