Does minification affect page rendering?

No. HTML minification only removes characters that have no effect on rendering — whitespace between tags, HTML comments, and optional end tags. The rendered output is identical.

What options are available?

Options include: remove comments, collapse whitespace, remove optional closing tags, remove redundant attributes, and inline CSS/JS minification.

Is minifying HTML worth doing?

For large HTML documents, minification can reduce size by 5–20%. The benefit is modest since HTML is already compressed by gzip/Brotli in transit. Most meaningful savings come from minifying CSS and JavaScript instead.

Will minification break my HTML?

No, if used with default settings. The "remove optional closing tags" option is safe per the HTML5 spec. The only risky option is collapsing whitespace inside pre, textarea, or script tags — the tool preserves whitespace in those elements by default.
