CSS Minifier compresses pasted CSS snippets for embeds, prototypes, and quick shipping. It removes comments and unnecessary whitespace locally in the browser.
Remove comments and extra whitespace from CSS snippets. Everything runs locally in this tab.

No. Processing happens locally in the browser tab. Your input is not sent to a server.
Shrinking a small CSS snippet for a code embed, style prototype, or quick inline <style> block before shipping it.
It strips /* comments */, collapses all whitespace and line breaks into single spaces, and removes the space around { } : ; , and > characters.
No. This is a whitespace-and-comment minifier only — it doesn't shorten hex colors (like #ffffff to #fff), merge duplicate rules, or rename custom properties the way a build-tool minifier like cssnano would.
It's designed for small snippets, embeds, and prototypes. For a full production build, a build-time minifier integrated into your bundler will catch more optimizations and is easier to keep in a repeatable pipeline.
Whitespace inside string values (e.g. content: " ";) is preserved since the minifier only touches whitespace between selectors and declarations, not inside quoted strings.
Either works — there's no artificial size limit, though very large stylesheets are better handled by a build-tool minifier that can also merge and dedupe rules.
