Minify HTML, strip comments and whitespace while protecting pre/script/style, with a size-saved readout.
Paste or type your input here, HTML Minifier is loading…
HTML Minifier strips the characters that bloat HTML without affecting how it renders, extra whitespace, line breaks, and comments, producing a smaller file that loads and transfers faster.
It's safe because the removed characters don't change rendering: a browser parses minified HTML identically to formatted HTML, so the page looks exactly the same while weighing less. The tool reports the size saved so you can see the gain, which is largest on heavily-indented or comment-rich source.
There are a few places where whitespace does matter, inside <pre> and <textarea>, and between inline elements that rely on a space, and these are the spots to sanity-check after minifying if a layout looks slightly off. Otherwise the transformation is transparent.
Minification runs in your browser, so your code stays private. Keep an unminified copy for editing, automate it in your build for production sites, and use this tool for one-offs, email HTML, and quick checks. Pair it with the CSS Minifier and other ToolsMonk developer tools.
