Frequently Asked Questions
Does minification affect functionality?
No. Minification only removes unnecessary characters (whitespace, comments) without changing the code's behavior. The minified code will function identically to the original.
How much can minification reduce file size?
Typical savings range from 10-30% for HTML and CSS, and 20-50% for JavaScript with extensive comments. Gzip compression on top of minification can achieve 70-90% total reduction.
