CSS Minifier & Beautifier — frequently asked questions
What does this page set for Beautify CSS?
Operation Mode: beautify. All of these stay editable.
Is my file uploaded?
No. On the web this tool runs in your browser, so your file is not uploaded.
Are there limits?
It takes one input per run. Server jobs accept up to 0 GB. A job can run for up to 15 seconds. In the browser, the practical limit is your device's memory.
What is the difference between minifying and beautifying CSS?
Minifying eliminates comments, redundant whitespace, trailing semicolons, and shortens color hex codes to minimize stylesheet file weight. Beautifying expands condensed rules into cleanly indented, human-readable blocks.
Does minification break complex CSS like media queries or CSS variables?
No. The parser preserves valid media queries (`@media`), custom property declarations (`--variable`), CSS keyframe animations, and pseudo-selectors safely.
