What is a CSS Minifier?
Minification reduces the size of your CSS files by removing unnecessary characters (spaces, comments, and formatting), making pages load faster and saving bandwidth. This tool performs safe minification suitable for production use.
Why use it?
Smaller CSS files mean faster downloads, better performance scores, improved SEO, and a smoother user experience on mobile networks.
- Q: Will minifying break my styles?
- A: No — the tool removes only non-functional characters. However, if you use hacks relying on comments or special formatting, review results before deploying.
- Q: Can I undo minification?
- A: You can format (beautify) minified CSS to make it readable again, but comments are lost. Keep a copy of your original source for maintenance.
- Q: Is my CSS uploaded to a server?
- A: No — everything runs in your browser.
