CSS Minifier and Beautifier
Switch CSS between compact and readable forms without uploading a stylesheet. Minification removes unnecessary formatting, while beautifying helps you inspect and edit rules during development.
How to use this tool
- Paste CSS into the input editor.
- Choose the minify or beautify operation and adjust the available options if needed.
- Review the output, then copy or download the transformed stylesheet.
Tips
- Keep an unminified source stylesheet in version control; minified CSS is primarily a delivery artifact.
- Check comments and special values after minification when a stylesheet uses unusual formatting or embedded content.
Frequently asked questions
Does minifying CSS change how it works?
The tool removes unnecessary whitespace and comments while preserving normal CSS values and rules. Always review unusual or generated CSS after transforming it.
Is my stylesheet uploaded?
No. CSS processing runs locally in your browser.
