CSS Minifier
Compress your CSS file to a fraction of its original size.
What does this CSS minifier do?
It compresses your stylesheet by stripping out comments, whitespace, line breaks, and the last semicolon in every rule. The CSS still works exactly the same in the browser, it just ships in fewer bytes so your pages load faster.
Why minify CSS files?
Big stylesheets are one of the slowest assets on most websites. Browsers must download the full file before they can paint above the fold content. Minified CSS reaches the browser sooner, which improves First Contentful Paint and Largest Contentful Paint scores.
How do you use this tool?
- Paste the contents of your style.css file.
- Click Minify CSS.
- Copy the output or download a styles.min.css file.
- Replace the original file on your server, or load the minified version in production while keeping the unminified copy for development.
When should you keep both versions?
Always keep an unminified source in your project. Edit the source, then run it through this tool when you deploy. If you only keep the minified copy, future edits will be painful because everything sits on a single line.
