What it does
Strip whitespace, comments, and empty attributes from HTML to reduce file size. Works on full pages, fragments, or email templates — anywhere clean indented HTML needs to ship compact.
Content inside <script>, <style>, <pre>, and <textarea> blocks is preserved verbatim by default — minifying those changes semantics.
