Choose the options: remove comments, collapse whitespace, and trim attribute quoting where safe.
Click Minify - the output shows size savings, and any questionable markup is flagged instead of silently mangled.

Frequently asked questions

Is this minifier safe to run on any HTML?

It is deliberately conservative - it only removes comments, collapses whitespace outside protected elements (script, style, pre, textarea) and applies safe quote trimming. It will not reorder or rewrite your markup.

What does it protect?

Anything inside script, style, pre, textarea and comments is left byte-identical so their content cannot be corrupted.

How much can I save?

Typically 10-25% for everyday HTML from frameworks that indent heavily; comment-heavy pages (like generated docs) can save far more.

What happens with invalid HTML?

The tool counts open/close tags and flags mismatches it detects, and warns instead of outputting corrupted structure.

Does minifying affect SEO?

No - Google does not penalize minified HTML, and smaller pages load faster, which helps Core Web Vitals.

Is my code sent anywhere?

No. Minification is computed locally in your browser.

Does minifying HTML break <pre> or <textarea> tags?

No. Whitespace inside whitespace-sensitive elements like
