What does HTML minification do?

Minification strips out characters that are not needed for the browser to render the page — such as whitespace between tags, newlines, and comments. This reduces the file size, which speeds up page load times.

Is it safe to remove HTML comments?

Yes for most cases. Regular HTML comments are ignored by browsers and safe to delete. This tool preserves IE conditional comments ( ) since those affect rendering in legacy browsers.

Will minifying break my inline scripts or styles?

No. This tool detects and preserves the contents of , , , and tags exactly as written, so your JavaScript, CSS, and preformatted text are never touched.

What are boolean attributes and why collapse them?

Boolean attributes like disabled, checked, or required don't need a value — writing disabled is equivalent to disabled="disabled". Collapsing them saves a few bytes per attribute and is fully valid HTML5.
