Frequently asked questions
- How does minifying HTML reduce file size?
- It collapses runs of whitespace to a single space, removes the gaps between tags and optionally strips comments. The page renders identically but transfers fewer bytes, so it loads faster.
- Will minifying break my page, pre blocks or scripts?
- No. The contents of pre, textarea, script and style tags are preserved exactly, so formatted code, inline JavaScript and CSS keep their original spacing.
- Are conditional comments removed?
- No. Conditional comments like <!--[if IE]> are kept because they affect rendering. Only ordinary comments are removed, and only when you leave the option on.
- Is my HTML uploaded anywhere?
- No. Minifying runs entirely in your browser — your markup never leaves your device.
