About Minify HTML Online
HTML written with readable indentation is great for editing but adds unnecessary bytes to every page load — comments, extra whitespace between tags, and multiple consecutive spaces all get sent to every visitor for no functional benefit. This tool strips all of that out, producing a smaller HTML payload that renders identically.
The minifier removes HTML comments entirely, collapses whitespace between tags down to nothing, and reduces runs of multiple spaces to a single space — safe transformations that don't change how the page actually renders, since HTML doesn't treat whitespace between block-level tags as meaningful content.
This is a lightweight, safe minifier rather than a full HTML-aware minifier like html-minifier-terser — it won't minify inline JavaScript or CSS within `<script>`/`<style>` tags, and it doesn't remove optional closing tags or attribute quotes. For most static pages, it still meaningfully reduces file size with zero risk of breaking rendering.
How it works
- Paste your HTML. Any formatted or partially formatted HTML document.
- Comments and whitespace strip automatically. See the size reduction percentage live.
- Copy the minified result. Ready to deploy as a smaller HTML payload.
