Frequently Asked Questions
Does minification change how my page looks?
No, minification only removes non-essential characters like comments and whitespace. The visual appearance remains exactly the same.
How much file size reduction can I expect?
Typical reduction ranges from 20% to 40%, depending on how much whitespace and comments existed in your original HTML.
Should I minify HTML during development?
No, keep your development HTML readable with proper formatting. Only minify when deploying to production.
What is the difference between minification and compression?
Minification removes unnecessary characters from the code itself. Compression (like gzip) compresses the file during transfer.
