CSS Formatter & Minifier
概要 CSS Formatter & Minifier
Our free online CSS Formatter & Minifier reformats your stylesheets with clean, consistent indentation, or strips out comments and whitespace to minimize file size for production.
Paste your CSS, pick format or minify, and copy the result - all processing happens entirely in your browser, with nothing ever uploaded to a server.
How to Use the CSS Formatter & Minifier
- Paste your stylesheet or CSS snippet into the input box
- Choose format to apply clean, consistent indentation, or minify to strip comments and whitespace
- Review the processed CSS in the output panel
- Copy the result and paste it into your stylesheet or build pipeline
Front-end developers use it to tidy up a stylesheet pulled from an old project or a theme they didn't originally write, so nested selectors and media queries are actually readable before making changes. Agencies preparing a static site for launch use minify mode to trim unnecessary bytes from the CSS bundle without touching a build tool. Designers reviewing a developer's handoff use the formatted output to check that spacing, colors, and breakpoints match what was specced. Because both modes run locally, proprietary styling for an unreleased product stays private.

Frequently asked questions
Does formatting validate my CSS?
No - it reformats spacing/indentation for readability but doesn't check for invalid property names or values. Use your browser's devtools console to catch actual CSS errors.
Is my CSS sent to a server?
No - formatting and minifying happen entirely in your browser.
Does minifying remove comments?
Yes - minify strips /* comments */ and all unnecessary whitespace to reduce file size for production use.
