Frequently Asked Questions

Does minification affect code functionality?

No! Minification only removes unnecessary whitespace and comments. The code functionality remains exactly the same.

Can I reverse minified code?

Yes, use the 'Beautify' button to add back formatting. However, comments are permanently removed during minification.

How much size reduction can I expect?

Typically 20-40% for CSS/JS and 10-30% for HTML. The exact amount depends on your code style and comments.

Should I minify code for development?

No, keep code readable during development. Only minify for production deployment to improve performance.
