Frequently Asked Questions

Find Quick Answers

What does CSS optimization do?

CSS optimization removes unnecessary characters like whitespace, comments, and redundant code to reduce file size, which improves website loading speed and performance.

Will the optimized CSS break my website?

No, the optimization process only removes formatting and comments while preserving all functional CSS rules. Your website should work exactly the same with optimized CSS.

What's the difference between minification and optimization?

Minification specifically removes whitespace and comments. Optimization includes minification plus additional improvements like sorting properties and removing redundant declarations.

Is there a file size limit?

There's no strict limit, but very large CSS files (over 1MB) may take longer to process. For best performance, optimize CSS files individually.
