Definition
A CSS Minifier is a developer performance tool that removes all unnecessary characters from your Cascading Style Sheets (CSS) without changing how the code functions in the browser. It strips out whitespace, line breaks, indentation, and comments.
Use Cases
Minifying your CSS before deploying to a live server is a standard web development best practice.
The Mechanics
Our tool processes your CSS string through a series of strict regex replacements to strip the fat.
Whitespace RemovalRemoves all spaces, tabs, and newlines that are used purely for human readability.
Comment StrippingDeletes all standard CSS comments (/* comment */) as the browser ignores them anyway.
Syntax ShorteningRemoves unnecessary spaces around colons (:), semicolons (;), commas (,), and brackets ({}).
Capabilities
Your code is compressed in real-time as you type or paste it in.
See exactly how many bytes you saved before and after minification.
Easily copy the compressed string to your clipboard for deployment.
Your stylesheets never leave your browser. Processing is done entirely locally.
Step-by-Step
Paste your formatted, readable CSS code into the left input panel.
The tool instantly strips out all comments and whitespace in the right panel.
Look at the stats below the output to see how much file size you saved.
Click the copy button and paste the minified code into your production files.
FAQ
No. The minifier only removes characters that the browser ignores (like spaces and comments). The CSS syntax and rules remain completely intact.
If you are trying to read or edit production CSS that has already been minified, use our CSS Formatter to make it readable again.
