# CSS Minifier & Stylesheet Compressor

Minify CSS files by stripping comments, whitespace, and redundant characters with verified byte-reduction metrics.

## What is CSS Minifier & Stylesheet Compressor?

The CSS Minifier shrinks stylesheets for production by removing comments, indentation, line breaks and unnecessary spaces around braces, colons and semicolons. Smaller CSS downloads faster and blocks rendering for less time, which helps Core Web Vitals. The rules themselves are not changed, so the page renders identically.

## How to use CSS Minifier & Stylesheet Compressor

1. **Paste your CSS** — Paste the stylesheet you want to compress.
2. **Minify** — The minified CSS appears instantly.
3. **Copy to production** — Copy the result into your .min.css file or inline <style> block.

## Frequently asked questions

### How much smaller will my CSS be?

Usually 15–30% before gzip, depending on how many comments and how much indentation the original has.

### Is minified CSS safe to use?

Yes. Only characters that browsers ignore are removed.

### Does it remove unused CSS?

No. Removing unused selectors requires analysing your HTML; this tool only removes whitespace and comments.
