Frequently asked questions
How much does minification reduce file size?
Typically 15-30% for CSS, 20-40% for JavaScript. Combined with Gzip compression, effective reduction is 60-80%.
Does minification affect functionality?
No, if done correctly. Minification only removes whitespace and comments. For JS, be careful with variable renaming (uglification) — test thoroughly.
