HTML Minifier
Shrink your HTML safely — comments removed, whitespace collapsed, content preserved.
The HTML Minifier strips comments and collapses unnecessary whitespace to produce the smallest valid HTML, and shows you the original size, minified size and percentage saved. It carefully protects the contents of pre and textarea tags so code samples and user text are never mangled. Smaller HTML means faster page loads, lower bandwidth bills and better scores on performance tests.
How to use the HTML Minifier
- Paste your full HTML document or snippet into the text box.
- Click Minify HTML — comments and extra whitespace are removed while pre and textarea content is kept intact.
- Check the size statistics, then use Copy Result to copy the minified HTML.
HTML Minifier — FAQs
Is the HTML minifier free?
Yes, completely free with no signup and no limits. Minify as many HTML files or snippets as you want, directly in your browser, as often as you like — ideal for daily production build workflows.
Will minifying break my page layout?
The tool is conservative: it only removes HTML comments and collapses redundant whitespace, and it protects pre and textarea content where whitespace is meaningful. Your tags, attributes and inline scripts are left untouched, so layout stays the same.
Is my HTML uploaded to a server?
No. Minification runs entirely in your browser using JavaScript, so your source code never leaves your device. That makes it safe for proprietary templates, client projects and unreleased pages you cannot share with third-party services.
Why minify HTML at all?
Smaller HTML downloads faster, which improves page-load speed, user experience and search-engine performance scores. It also reduces bandwidth usage and hosting costs, especially on high-traffic sites where every single kilobyte counts toward the budget overall.
