CSS Minifier
Minify CSS by removing comments, whitespace, and unnecessary characters.
Frequently Asked Questions
What does minification remove?
It removes comments, collapses whitespace, removes spaces around braces, colons, semicolons and commas, and drops trailing semicolons before closing braces.
Will minification break my CSS?
No. The minifier preserves all functional characters and selectors. The output is semantically identical to the input, just smaller.
How much can I save?
Typically 20–40% depending on how much whitespace and how many comments the original contained.
Is my CSS sent anywhere?
No. Minification happens entirely in your browser. Your code never leaves your device.
