Frequently Asked Questions
What's the difference between beautify and minify?
Beautify expands your CSS with proper indentation, line breaks, and spacing for readability. Minify does the opposite — removes all unnecessary whitespace, comments, and characters to produce the smallest possible file for production.
Can I customize the indentation?
Yes. Choose between spaces or tabs, and set the indent size to 2, 4, or 8 spaces. You can also choose whether opening brackets go on the same line or a new line.
Does it sort CSS properties alphabetically?
Yes, there's an optional 'Sort properties' toggle. When enabled, properties within each rule block are sorted alphabetically (e.g., background before color before display).
Can I upload a .css file?
Yes. Click the Upload button to load a .css, .scss, or .less file (up to 5MB). The contents will be loaded into the input editor.
Does it remove CSS comments?
Optionally. Toggle 'Remove comments' in the options panel. This is useful when preparing CSS for production or when you want to strip out development notes.
What does the CSS Analysis section show?
It shows detailed stats about your CSS: total characters, lines, rules (blocks), selectors, properties, comments, and media queries. This helps you understand the complexity of your stylesheet.
Is my CSS code safe?
Completely. All formatting happens 100% in your browser using JavaScript. Your CSS code is never sent to any server — you can verify this by checking the Network tab in your browser's developer tools.
Can I use the output as new input?
Yes. After formatting, click 'Use as Input' to move the output back to the input editor. This is useful for iterating on formatting options.
