About HTML Minifier — Free Online Tool

HTML Minifier deletes comments and surplus whitespace from markup so the document ships fewer bytes.

Three passes do all of it: HTML comments are removed, whitespace between a closing tag and the next opening tag disappears, and any run of two or more spaces collapses to one. Attributes are left alone — optional quotes stay, nothing is reordered, no tag is dropped. Two consequences are worth checking before you ship the output: the whitespace collapse applies inside <pre> and <textarea> too, and a conditional comment goes the same way as an ordinary one.

Minification happens in your browser; the markup is not uploaded in order to be processed.

Shrinking a static page before upload, trimming an email template to fit a sending limit, stripping build comments out of generated markup, and finding out how much of a file is whitespace.
