Frequently asked questions
Does this change how my CSS renders?+
No, only comments and non-essential whitespace are removed. Selectors, property values, and content inside quoted strings are left exactly as written.
Can I reverse the minification?+
Not with this tool, minifying is a one-way transform. Keep your original, formatted CSS file as the source of truth.
Does it rename classes or IDs?+
No, this is whitespace-and-comment minification only, not a build-tool-style optimizer that renames selectors.
