Why minify HTML?

HTML minification reduces page weight by removing content that browsers don't need: all HTML comments, extra whitespace between tags, and blank lines. The markup remains functionally identical but downloads faster — especially noticeable on slow connections or large documents. This tool uses regex-based minification and removes all HTML comments without exception, collapses inter-tag whitespace to nothing, and squashes any remaining multi-space runs to a single space. All processing runs locally in your browser — nothing is sent to a server. Note: this is a lightweight approach suitable for most static HTML. Complex pages with inline scripts may require a dedicated build-tool minifier.
