Minify CSS and see how many bytes you saved.

About this tool
The CSS Minifier shrinks stylesheets by removing comments, collapsing whitespace and dropping redundant semicolons. The before/after byte counts show exactly how much you saved — typically 20–40% on hand-written CSS.
Smaller stylesheets mean faster first paint, especially on mobile connections, and page speed is a confirmed ranking factor. Minify as a final build step and keep your readable source files for development.
Frequently asked questions
The minifier only removes characters that browsers ignore. Selectors, values and rule order are untouched, so rendering is identical.
Formatting can be re-expanded by any CSS beautifier, but comments are permanently removed — keep your original source file.
Combine first, then minify the result, so the byte savings apply to everything you ship.
