CSS Minifier
Minify CSS by removing comments, collapsing whitespace, shortening zero values, and removing unnecessary semicolons.
What is CSS Minification?
CSS minification removes all unnecessary characters from your stylesheets โ comments, whitespace, newlines, and redundant semicolons โ without affecting how the browser interprets the styles. It can also optimize shorthand properties and shorten zero values (e.g., 0px to 0). Smaller CSS files mean faster download times and quicker first paint, which directly impacts user experience and search engine rankings.
How to Minify CSS
Paste your CSS code into the input panel. The tool accepts any valid CSS including media queries, keyframes, and custom properties.
Toggle options like removing last semicolons and shortening zero values for additional compression.
Click Minify to compress. View the size comparison between original and minified output, then copy the result.
