Questions about HTML Minifier
Common questions about minified HTML and semantic structure.
Should I minify the source HTML?
No. It is recommended to keep a readable version for development and serve a minified output in production.
Does minification change semantics?
It should not. The tool removes unnecessary characters, but it does not fix unclosed tags or broken HTML structure.
Is it advisable to remove all comments?
In production it is usually recommended, except for conditional comments or markers you need to keep for a specific reason.
