Why minify HTML?

Minifying HTML removes the whitespace and comments that browsers ignore, reducing the number of bytes sent to visitors. Smaller HTML means faster first paint and lower bandwidth — a small but real performance win for production sites.

Frequently Asked Questions

Will minifying break my page?

No — it preserves the content of pre, textarea, script, and style elements, and only collapses ignorable whitespace elsewhere.

Should I keep an un-minified copy?

Yes — minify for production, but keep your readable source for editing. Use the HTML Formatter to expand it again.

Is it free and private?

Yes — it's 100% free with no signup, and everything runs locally in your browser, so your data is never uploaded to a server.
