What does HTML minification remove?

HTML minification removes whitespace between tags, HTML comments, optional closing tags, and redundant attributes while preserving the document's structure.

Does minified HTML affect rendering?

No, browsers ignore extra whitespace and comments when rendering HTML. Minified HTML renders identically to the original.
