CSS Formatter & Minifier is a 100% free, browser-based utility that enables you to beautify or minify css and see the size savings. Unlike traditional cloud converters, all processing executes locally on your device with zero server uploads, delivering immediate results and ironclad data privacy.
About the CSS Formatter & Minifier
Minified CSS is great for performance but impossible to read. The CSS Formatter expands it into one declaration per line with consistent indentation, which makes debugging and editing much easier.
Minify mode does the reverse: it strips comments, whitespace and redundant semicolons to reduce file size, and reports exactly how many bytes you saved. Smaller stylesheets download and parse faster, improving Core Web Vitals.

Frequently asked questions
How much smaller does minified CSS get?
Typically 15–30% for hand-written stylesheets, depending on how many comments and how much whitespace they contain. Combined with gzip or Brotli compression on your server the savings are even larger.
Is minification safe?
Yes. Minification only removes characters that have no effect on how the CSS is interpreted, such as comments, extra whitespace and the last semicolon in a block. Strings and url() values are preserved.
Can I format SCSS or LESS?
Basic SCSS and LESS syntax such as nesting usually formats correctly in Beautify mode, but the minifier is designed for plain CSS.
