Why Minify HTML?
Minified HTML can reduce the amount of markup that needs to be transferred and can make source files more compact. The amount saved depends on the original document and the selected settings. HTML minification is one part of a broader website performance workflow.

Comment removal can reduce source size when comments are not needed in production. Whitespace and line-break options reduce formatting characters. Optional boolean-attribute and quote optimizations should be reviewed before deployment.
