CSS Minifier & Formatter
Format readable CSS for editing or minify it for a lighter production stylesheet.
Complete Guide & FAQ
What is the CSS Minifier & Formatter?
It cleans up, organizes, and compresses stylesheets instantly. Paste your CSS (or upload the file) and choose to minify it for production, stripping comments and unnecessary whitespace, or format it with readable indentation for development.
What it does
- Minify: removes comments, whitespace, and line breaks to reduce file weight.
- Format: re-indents the CSS consistently, ideal for reviewing or debugging.
- Syntax validation: catches unclosed braces, quotes, or comments before processing.
- File upload & download: upload a .css file and download the minified result with one click.
Frequently Asked Questions (FAQ)
Does it catch syntax errors in my CSS?
Yes. It validates unclosed braces, unclosed comments, and unclosed strings, and reports the exact line and column of the problem before minifying or formatting.
Can I upload a .css file instead of pasting the code?
Yes, the upload button loads the file's content directly into the editor and minifies it automatically.
How much does it reduce the file size?
It depends on the original CSS, but removing comments, whitespace, and unnecessary line breaks usually cuts file size by 15% to 40%, improving your site's load time.
