url(...), and quoted values are preserved.Tool Introduction
Compress CSS to its smallest equivalent form by removing comments, collapsing whitespace, and stripping the trailing semicolon before each closing brace.
Tool Overview
CSS minification removes characters the browser does not need to render styles correctly. This tool strips /* ... */ comments, collapses runs of whitespace outside of strings, and removes whitespace around structural punctuation ({ } : ; , >). Strings inside url(...) and quoted values are preserved exactly. Byte counts before and after are reported so you can see the savings at a glance. Everything runs in your browser.
Use Cases
- Inline critical CSS into <head> with the minimum possible bytes.
- Quickly compress hand-written CSS without spinning up a build pipeline.
- Squeeze additional bytes out of stylesheets already processed by Tailwind or PostCSS.
