About the CSS Minifier
Compress CSS: remove comments and whitespace, shorten #AABBCC hex colors to #ABC, drop units on zero values, strip the last semicolon per declaration block, and collapse extra semicolons — all without side effects.
Frequently asked questions
Is it safe for all valid CSS?
Yes — only redundant bytes are removed; declarations and selectors are untouched.
How much smaller will my CSS get?
Typical savings are 20–40% on hand-written stylesheets, more on heavily commented ones.
