Minifies CSS by removing comments and unneeded whitespace.
CSS Minify strips comments and collapses unneeded whitespace from your stylesheets to make them smaller. Paste in your CSS and it removes /* */ comments, extra spaces and line breaks, the whitespace around braces, colons, semicolons and commas, and trailing semicolons before a closing brace. It is handy for quickly compressing CSS by hand when you don't want to wire up a full build step.
No. CSS Minify runs entirely in your browser and nothing is uploaded. Your stylesheet never leaves your device.
It deletes /* */ comments, collapses runs of whitespace into a single space, removes whitespace around { } : ; and , characters, and drops a trailing semicolon right before a closing brace.
No. It is a whitespace and comment minifier only. It does not parse the CSS, shorten hex colors, merge duplicate rules, or reorder anything, so your selectors and declarations stay intact.
Standard /* ... */ comment blocks are removed safely. Because the tool uses simple text replacement rather than a full CSS parser, content inside string values or url() that resembles comment markers could be affected, so review the output for unusual cases.
There is no fixed limit; processing happens locally in your browser, so very large stylesheets are bounded only by your device's memory and performance.
