Frequently Asked Questions
Will minifying HTML break inline JavaScript or CSS?
The minifier focuses on structural HTML whitespace and comments. If your markup contains complex inline scripts with single-line comments, ensure statements end with semicolons or use dedicated JS minifiers.
How much file size reduction can I expect?
Typical HTML documents see between 15% and 40% file size reduction depending on the volume of comments, blank lines, and nested indentation in the original file.
