Frequently asked questions

What does HTML minification remove?

Minification removes unnecessary whitespace, line breaks, comments, and optional closing tags where allowed by HTML5 spec. It creates the smallest valid HTML output.

How much file size reduction can I expect?

Typical reduction is 10-30% depending on code style. HTML with lots of comments and indentation compresses more. The tool shows exact before/after byte counts.

Is minified HTML still valid?

Yes, minified HTML is fully valid and renders identically to formatted HTML. Minification only removes redundant characters that don't affect parsing or display.
