よくある質問と回答
Does minifying CSS break my website layout?
No. Minification only strips non-functional whitespace and comments.

Where supported, tool inputs and files are processed locally inside your web browser using WebAssembly and HTML5 Canvas. Your files are not uploaded to NexVaani file-processing servers.
