Frequently Asked Questions
What is the difference between minifying and beautifying CSS?
Minification strips all unnecessary whitespace, newlines, and comments to reduce file size for faster web loading. Beautifying formats messy or compressed CSS with consistent indentation so humans can read and edit it easily.
Will minifying CSS break my website styles?
No. Minification preserves all CSS selectors, property rules, values, and cascading order. It only strips non-functional whitespace and comments.
How much file size reduction can I expect?
Depending on your code structure and amount of comments, CSS minification typically reduces file size by 15% to 40%, directly improving page load speed and Core Web Vitals.
Is my stylesheet uploaded to a remote server?
No. All minification and formatting algorithms run strictly in your local browser using client-side JavaScript. Your code never leaves your device.
Privacy First
Minification and formatting are performed 100% in your browser. Stylesheet code is never stored or uploaded.
