CSS Minifier Tips

  • Powered by CSSO - a structural optimizer that merges and restructures rules, not just a whitespace stripper.
  • Overridden declarations are removed automatically: later rules win, earlier duplicates disappear.
  • margin: 0px becomes margin: 0 and colors like #ff0000 become red where shorter.
  • Load the sample to see rule merging in action - overridden properties simply vanish.

전문적인 CSS Minifier 처리 기능

CSS Minifier 데이터를 효율적이고 전문적으로 다루는 데 필요한 모든 것

CSSO Engine

A structural CSS optimizer that understands the cascade, not just a whitespace stripper.

Clean Output

Comments stripped, whitespace collapsed, declarations folded to shortest form.

Rule Merging

Duplicate and overridden declarations disappear while the cascade stays intact.

Safe Optimization

Declarations are only removed when a later rule guarantees to override them.

Size Report

Bytes before and after, plus the exact percentage saved, on every run.

Private by Design

Your styles stay in the browser tab. Nothing is uploaded, ever.

자주 묻는 질문

Css Minifier 서식 지정에 대한 일반적인 질문에 답변합니다

Yes, completely free with no registration. All minification happens locally in your browser.

CSSO (CSS Optimizer) - a structural optimizer from the Yandex/Ozon ecosystem that merges selectors, folds shorthands and removes overridden declarations, going well beyond simple whitespace removal.

No. CSSO preserves the cascade: declarations removed are ones guaranteed to be overridden later, so the rendered result is identical.

No - those need to be compiled to CSS first. Feed the compiled .css output here for the final size squeeze.

Readable, well-indented CSS typically shrinks 40-70% thanks to whitespace removal plus CSSO restructuring. The size report shows the exact savings.
