The HTML minifier reduces HTML file size by removing comments, inter-tag whitespace, and redundant attributes. See the exact bytes saved to quantify the page performance improvement.

How HTML Minification Works
HTML minification removes the parts of your HTML that browsers don't need to render the page: comments, whitespace between tags, and redundant line breaks. The resulting HTML is functionally identical but smaller.
Safe to Minify
Whitespace between block elements (div, p, header, footer) is safe to remove. HTML comments are safe to remove. Pre-formatted content (<pre> tags) is preserved as-is since whitespace is significant inside <pre> blocks.
FAQ
Is this HTML minifier free?
Yes, completely free with no signup. All minification runs locally in your browser.
What does HTML minification do?
HTML minification removes whitespace between HTML tags, removes HTML comments, and eliminates redundant attributes. The result is functionally identical HTML that is smaller in file size.
Will minifying HTML break my page?
For most HTML, minification is safe. However, whitespace can be significant in some contexts (like <pre> blocks or inline elements). Always test the minified output before deploying to production.
Are script and style tags handled?
The tool optionally minifies inline CSS in <style> tags and inline JavaScript in <script> tags. CSS and JS inside these tags use whitespace-removal-only minification.
How much space does HTML minification save?
Typical HTML files see 10-25% reduction from minification alone. Combined with gzip compression (which most web servers apply automatically), total savings are typically 60-75%.
