HTML Minifier Online
Loading tool...
When you write HTML code, you use tabs, spaces, line breaks, and comments so human developers can read it. But the web browser doesn't care about any of that whitespace; it just wastes bandwidth and hurts your Google PageSpeed Insights score. This minifier is built to instantly compress your raw HTML into a highly optimized, production-ready block.
Safe Regex Stripping
The minifier uses complex Regex parsing logic to safely strip away unnecessary indentation, collapse empty lines, and delete developer comments (<!-- -->). By reducing the file to a single continuous string, you can often shrink your HTML payload size by 15% to 30%, resulting in faster Time-to-First-Byte (TTFB).
Protecting Sensitive Tags
A cheap minifier will just delete all spaces globally, which will completely break your website. This tool is programmed to ignore the contents inside <pre>, <textarea>, <script>, and <style> tags. This ensures your preformatted text blocks and inline JavaScript logic remain fully functional.
The Inline-Block CSS Bug
Be aware: If you rely on the CSS display: inline-block property for your layout, browsers naturally render a 4px gap based on the line-breaks in your HTML code. Minifying the HTML deletes those line-breaks, which will collapse that 4px gap and might slightly shift your layout.
