Frequently Asked Questions
How much file size reduction can I expect?
Typical savings are 10–40% for HTML, 15–50% for CSS, and 30–60% for JavaScript, depending on code verbosity and comment density.
Does minification affect functionality?
No — minification only removes whitespace and comments. It does not alter logic or rename variables (that would be obfuscation).
Is CSS variable and custom property minification supported?
Yes. CSS custom properties, variables, and modern syntax are all handled correctly.
