How do I minify HTML?

Paste your HTML code, configure minification options (remove comments, whitespace, empty elements, redundant attributes), and minify. The tool compresses HTML instantly with detailed file size reduction statistics and compression ratio.

Is this HTML minifier free?

Yes, completely free with unlimited minification. No signup required, no watermarks. All compression happens in your browser for complete privacy of HTML files and templates.

Are HTML files uploaded to servers?

No, all HTML minification happens locally in your browser. Files never leave your computer, ensuring complete privacy for client projects and proprietary templates.

Is it safe to remove optional HTML tags?

Removing optional tags like <html>, <head>, and <body> is technically valid HTML5 but may cause issues with some parsers or frameworks. Use this option carefully and test thoroughly.

Will minification break my HTML functionality?

The minifier is designed to preserve functionality while reducing size. However, always test minified HTML, especially when using aggressive options like removing optional tags.

How much compression can I expect?

Compression ratios vary based on your HTML structure. Typical savings range from 10-30% for well-formatted HTML, with higher savings for HTML with extensive whitespace and comments.

Should I minify inline CSS and JavaScript?

Yes, minifying inline styles and scripts can provide additional savings. However, for large amounts of CSS/JS, consider using separate files with dedicated minifiers for better optimization.

Can I preserve certain comments in my HTML?

The minifier can preserve IE conditional comments which are often important for legacy browser support. Other comments are removed by default for maximum compression.
