Beautify, minify, and lint CSS. Configurable indentation, property ordering, and line length. Converts minified CSS to readable and readable CSS back to minified.
Open CSS Formatter → free, no sign-inCSS that arrives from a build tool, a third-party plugin, or an older codebase is often minified or inconsistently formatted — technically valid but unreadable. The CSS Formatter beautifies it: consistent indentation, one property per line, sorted declarations if you prefer, and a clean structure that's actually maintainable. The minify option works in reverse for production output. The linter catches common mistakes.
Developers inheriting legacy CSS, inspecting third-party stylesheets, cleaning up auto-generated output, or just wanting their own code consistently formatted before committing it.
No tutorials. No learning curve. Open it and get started.
No server uploads. Configurable formatting preferences — indentation size, line length, property ordering — so the output matches your project's existing code style.
Completely free. No trial period. No premium tier for basic functionality. No account required. Use it as often as you need.
One job, done well. CSS Formatter was built to solve a specific problem cleanly. No feature bloat, no ads, no distractions.
Does minifying CSS improve performance?
Yes — minified CSS loads faster due to reduced file size and fewer HTTP bytes transferred.
What does the linter check for?
Common CSS errors including invalid property names, missing semicolons, and duplicate selectors.
Can I sort CSS properties?
Yes — alphabetical property sorting is available.
Does it handle SCSS or Less?
The tool is designed for plain CSS.
Will formatting change how my CSS works?
No — formatting only affects whitespace and indentation, not the CSS rules themselves.
Free. Instant. No sign-in. Open it and get the job done.
